Quick Chat: Scott Gershin from The Sound Lab at Technicolor

By Randi Altman

Veteran sound designer and feature film supervising sound editor Scott Gershin is leading the charge at the recently launched The Sound Lab at Technicolor, which, in addition to film and television work, focuses on immersive storytelling.

Gershin has more than 100 films to his credit, including American Beauty (which earned him a BAFTA nomination), Guillermo del Toro’s Pacific Rim and Dan Gilroy’s Nightcrawler. But films aren’t the only genre that Gershin has tackled — in addition to television work (he has an Emmy nom for the TV series Beauty and the Beast), this audio post pro has created the sound for game titles such as Resident Evil, Gears of War and Fable. One of his most recent projects was contributing to id Software’s Doom.

We recently reached out to Gershin to find out more about his workflow and this new Burbank-based audio entity.

Can you talk about what makes this facility different than what Technicolor has at Paramount? 
The Sound Lab at Technicolor works in concert with our other audio facilities, tackling film, broadcast and gaming projects. In doing so we are able to use Technicolor’s world-class dubbing, ADR and Foley stages.

One of the focuses of The Sound Lab is to identify and use cutting-edge technologies and workflows not only in traditional mediums, but in those new forms of entertainment such as VR, AR, 360 video/films, as well as dedicated installations using mixed reality. The Sound Lab at Technicolor is made up of audio artists from multiple industries who create a “brain trust” for our clients.

Scott Gershin and The Sound Lab team.

As an audio industry veteran, how has the world changed since you started?
I was one of the first sound people to use computers in the film industry. When I moved from the music industry into film post production, I brought that knowledge and experience with me. It gave me access to a huge number of tools that helped me tell better stories with audio. The same happened when I expanded into the game industry.

Learning the interactive tools of gaming is now helping me navigate into these new immersive industries, combining my film experience to tell stories and my gaming experience using new technologies to create interactive experiences.

One of the biggest changes I’ve seen is that there are so many opportunities for the audience to ingest entertainment — creating competition for their time — whether it’s traveling to a theatre, watching TV (broadcast, cable and streaming) on a new 60- or 70-inch TV, or playing video games alone on a phone or with friends on a console.

There are so many choices, which means that the creators and publishers of content have to share a smaller piece of the pie. This forces budgets to be smaller since the potential audience size is smaller for that specific project. We need to be smarter with the time that we have on projects and we need to use the technology to help speed up certain processes — allowing us more time to be creative.

Can you talk about your favorite tools?
There are so many great technologies out there. Each one adds a different color to my work and provides me with information that is crucial to my sound design and mix. For example, Nugen has great metering and loudness tools that help me zero in on my clients LKFS requirements. With each client having their own loudness requirements, the tools allow me to stay creative, and meet their requirements.

Audi’s The Duel

What are some recent projects you’ve worked on?
I’ve been working on a huge variety of projects lately. Recently, I finished a commercial for Audi called The Duel, a VR piece called My Brother’s Keeper, 10 Webisodes of The Strain and a VR music piece for Pentatonix. Each one had a different requirement.

What is your typical workflow like?
When I get a job in, I look at what the project is trying to accomplish. What is the story or the experience about? I ask myself, how can I use my craft, shaping audio, to better enhance the experience. Once I understand how I am going to approach the project creatively, I look at what the release platform will be. What are the technical challenges and what frequencies and spacial options are open to me? Whether that means a film in Dolby Atmos or a VR project on the Rift. Once I understand both the creative and technical challenges then I start working within the schedule allotted me.

Speed and flow are essential… the tools need to be like musical instruments to me, where it goes from brain to fingers. I have a bunch of monitors in front of me, each one supplying me with different and crucial information. It’s one of my favorite places to be — flying the audio starship and exploring the never-ending vista of the imagination. (Yeah, I know it’s corny, but I love what I do!)

HPA Tech Retreat takes on realities of virtual reality

By Tom Coughlin

The HPA Tech Retreat, run by the Hollywood Professional Association in association with SMPTE, began with an insightful one-day VR seminar— Integrating Virtual Reality/Augmented Reality into Entertainment Applications. Lucas Wilson from SuperSphere kicked off the sessions and helped with much of the organization of the seminar.

The seminar addressed virtual reality (VR), augmented reality (AR) and mixed reality (MR, a subset of AR where the real world and the digital world interact, like Pokeman Go). As in traditional planar video, 360-degree video still requires a director to tell a story and direct the eye to see what is meant to be seen. Successful VR requires understanding how people look at things, how they perceive reality, and using that understanding to help tell a story. Some things that may help with this are reinforcement of the viewer’s gaze with color and sound that may vary with the viewer — e.g. these may be different for the “good guy” and the “bad guy.”

VR workflows are quite different from traditional ones, with many elements changing with multiple-camera content. For instance, it is much more difficult to keep a camera crew out of the image, and providing proper illumination for all the cameras can be a challenge. The image below from Jaunt shows their 360-degree workflow, including the use of their cloud-based computational image service to stitch the images from the multiple cameras.
Snapchat is the biggest MR application, said Wilson. Snapchat’s Snapchat-stories could be the basis of future post tools.

Because stand-alone headsets (head-mounted displays, or HMDs) are expensive, most users of VR rely on smart phone-based displays. There are also some places that allow one or more people to experience VR, such as the IMAX center in Los Angeles. Activities such as VR viewing will be one of the big drivers for higher-resolution mobile device displays.

Tools that allow artists and directors to get fast feedback on their shots are still in development. But progress is being made, and today over 50 percent of VR is used for video viewing rather than games. Participants in a VR/AR market session, moderated by the Hollywood Reporter’s Carolyn Giardina and including Marcie Jastrow, David Moretti, Catherine Day and Phil Lelyveld, seemed to agree that the biggest immediate opportunity is probably with AR.

Koji Gardiner from Jaunt gave a great talk on their approach to VR. He discussed the various ways that 360-degree video can be captured and the processing required to create finished stitched video. For an array of cameras with some separation between the cameras (no common axis point for the imaging cameras), there will be area that needs to be stitched together between camera images using common reference points between the different camera images as well as blind spots near to the cameras where they are not capturing images.

If there is a single axis for all of the cameras then there are effectively no blind spots and no stitching possible as shown in the image below. Covering all the space to get a 360-degree video requires additional cameras located on that axis to cover all the space.

The Fraunhofer Institute, in Germany, has been showing a 360-degree video camera with an effective single axis for several cameras for several years, as shown below. They do this using mirrors to reflect images to the individual cameras.

As the number of cameras is increased, the mathematical work to stitch the 360-degree images together is reduced.

Stitching
There are two approaches commonly used in VR stitching of multiple camera videos. The easiest to implement is a geometric approach that uses known geometries and distances to objects. It requires limited computational resources but results in unavoidable ghosting artifacts at seams from the separate images.

The Optical Flow approach synthesizes every pixel by computing correspondences between neighboring cameras. This approach eliminates the ghosting artifacts at the seams but has its own more subtle artifacts and requires significantly more processing capability. The Optical Flow approach requires computational capabilities far beyond those normally available to content creators. This has led to a growing market to upload multi-camera video streams to cloud services that process the stitching to create finished 360-degree videos.

Files from the Jaunt One camera system are first downloaded and organized on a laptop computer and then uploaded to Jaunt’s cloud server to be processed and create the stitching to make a 360 video. Omni-directionally captured audio can also be uploaded and mixed ambisonically, resulting in advanced directionality in the audio tied to the VR video experience.

Google and Facebook also have cloud-based resources for computational photography used for this sort of image stitching.

The Jaunt One 360-degree camera has a 1-inch 20MP rolling shutter sensor with frame rates up to 60fps with 3200 ISO max, 29dB SNR at ISO800. It has a 10 stops per camera module, with 130-degree diagonal FOV, 4/2.9 optics and with up to 16K resolution (8K per eye). Jaunt One at 60fps provides 200GB/minute uncompressed. This can fill a 1TB SSD in five minutes. They are forced to use compression to be able to use currently affordable storage devices. This compression creates 11GB per minute, which can fill a 1TB SSD in 90 minutes.

The actual stitched image, laid out flat, looks like a distorted projection. But when viewed in a stereoscopic viewer it appears to look like a natural image of the world around the viewer, giving an immersive experience. At one point in time the viewer does not see all of the image but only the image in a restricted space that they are looking directly at as shown in the red box in the figure below.

The full 360-degree image can be pretty high resolution, but unless the resolution is high enough, the resolution inside the scene being viewed at any point in time will be much less that the resolution of the overall scene, unless special steps are taken.

The image below shows that for a 4k 360-degree video the resolution in the field of view (FOV) may be only 1K, much less resolution and quite perceptible to the human eye.

In order to provide a better viewing experience in the FOV, either the resolution of the entire view must be better (e.g. the Jaunt One high-resolution version has 8K per eye and thus 16K total displayed resolution) or there must be a way to increase the resolution in the most significant FOV in a video, so at least in that FOV, the resolution leads to a greater feeling of reality.

Virtual reality, augmented reality and mixed reality create new ways of interacting with the world around us and will drive consumer technologies and the need for 360-degree video. New tools and stitching software, much of this cloud-based, will enable these workflows for folks who want to participate in this revolution in content. The role of a director is as important as ever as new methods are needed to tell stories and guide the viewer to engage in this story.

Chris Hill & Sami Tahari

Imaginary Forces expands with EP Chris Hill and director of biz dev Sami Tahari

Imaginary Forces has added executive producer Chris Hill and director of business development Sami Tahari to its Los Angeles studio. The additions come at a time when the creative studio is looking to further expand their cross-platform presence with projects that mix VR/AR/360 with traditional, digital and social media.

Celebrating 20 years in business this year, the independently owned Imaginary Forces is a creative company specializing in brand strategy and visual storytelling encompassing many disciplines, including full-service design, production and post production. Being successful for that long in this business means they are regularly innovating and moving where the industry takes them. This led to the hiring of Hill and Tahari, whose diverse backgrounds will help strengthen the company’s long-standing relationships, as well as its continuous expansion into emerging markets.

Recent work of note includes main titles for Netflix’s beloved Stranger Things, the logo reveal for Michael Bay’s Transformers: The Last Knight and an immersive experience for the Empire State Building.

Hill’s diverse production experience includes commercials, experience design, entertainment marketing and branding for such clients as HBO Sports, Google, A&E and the Jacksonville Jaguars, among others. He joins Imaginary Forces after recently presiding over the broadcast division of marketing agency BPG.

Tahari brings extensive marketing, business and product development experience spanning the tech and entertainment spaces. His resume includes time at Lionsgate and Google, where he was an instrumental leader in the creative development and marketing of Google Glass.

“Imaginary Forces has a proven ability to use design and storytelling across any medium or industry,” adds Hill. “We can expand that ability to new markets, whether it’s emerging technologies, original content or sports franchises. When you consider, for example, the investment in massive screens and new technologies in stadiums across the country, it demands [that] same high level of brand strategy and visual storytelling.”

Virtual Reality Roundtable

By Randi Altman

Virtual reality is seemingly everywhere, especially this holiday season. Just one look at your favorite electronics store’s website and you will find VR headsets from the inexpensive, to the affordable, to the “if I win the lottery” ones.

While there are many companies popping up to service all aspects of VR/AR/360 production, for the most part traditional post and production companies are starting to add these services to their menu, learning best practices as they go.

We reached out to a sampling of pros who are working in this area to talk about the problems and evolution of this burgeoning segment of the industry.

Nice Shoes Creative Studio: Creative director Tom Westerlin

What is the biggest issue with VR productions at the moment? Is it lack of standards?
A big misconception is that a VR production is like a standard 2D video/animation commercial production. There are some similarities, but it gets more complicated when we add interaction, different hardware options, realtime data and multiple distribution platforms. It actually takes a lot more time and man hours to create a 360 video or VR experience relative to a 2D video production.

More development time needs to be scheduled for research, user experience and testing. We’re adding more stages to the overall production. None of this should discourage anyone from exploring a concept in virtual reality, but there is a lot of consideration and research that should be done in the early stages of a project. The lack of standards presents some creative challenges for brands and agencies considering a VR project. The hardware and software choices made for distribution can have an impact on the size of the audience you want to reach as well as the approach to build it.

The current landscape provides the following options:
YouTube and Facebook can hit a ton of people with a 360 video, but has limited VR functionality; a WebVR experience, works within certain browsers like Chrome or Firefox, but not others, limiting your audience; a custom app or experimental installation using the Oculus or HTC Vive, allows for experiences with full interactivity, but presents the issue of audience limitations. There is currently no one best way to create a VR experience. It’s still very much a time of discovery and experimentation.

What should clients ask of their production and post teams when embarking on their VR project?
We shouldn’t just apply what we’ve all learned from 2D filmmaking to the creation of a VR experience, so it is crucial to include the production, post and development teams in the design phase of a project.

The current majority of clients are coming from a point of view where many standard constructs within the world of traditional production (quick camera moves or cuts, extreme close-ups) have negative physiological implications (nausea, disorientation, extreme nausea). The impact of seemingly simple creative or design decisions can have huge repercussions on complexity, time, cost and the user experience. It’s important for clients to be open to telling a story in a different manner than they’re used to.

What is the biggest misconception about VR — content, process or anything relating to VR?
The biggest misconception is clients thinking that 360 video and VR are the same. As we’ve started to introduce this technology to our clients, we’ve worked to explain the core differences between these extremely difference experiences: VR is interactive and most of the time a full CG environment, while 360 is video and although immersive, it’s a more passive experience. Each have their own unique challenges and rewards, so as we think about the end user’s experiences, we can determine what will work best.

There’s also the misconception that VR will make you sick. If executed poorly, VR can make a user sick, but the right creative ideas executed with the right equipment can result in an experience that’s quite enjoyable and nausea free.

Nice Shoes’ ‘Mio Garden’ 360 experience.

Another misconception is that VR is capable of anything. While many may confuse VR and 360 and think an experience is limited to passively looking around, there are others who have bought into the hype and inflated promises of a new storytelling medium. That’s why it’s so important to understand the limitations of different devices at the early stages of a concept, so that creative, production and post can all work together to deliver an experience that takes advantage of VR storytelling, rather than falling victims to the limitations of a specific device.

The advent of affordable systems that are capable of interactivity, like the Google Daydream, should lead to more popular apps that show off a higher level of interactivity. Even sharing video of people experiencing VR while interacting with their virtual worlds could have a huge impact on the understanding of the difference between passively watching and truly reaching out and touching.

How do we convince people this isn’t stereo 3D?
In one word: Interactivity. By definition VR is interactive and giving the user the ability to manipulate the world and actually affect it is the magic of virtual reality.

Assimilate: CEO Jeff Edson

What is the biggest issue with VR productions at the moment? Is it lack of standards?
The biggest issue in VR is straightforward workflows — from camera to delivery — and then, of course, delivery to what? Compared to a year ago, shooting 360/VR video today has made big steps in ease of use because more people have experience doing it. But it is a LONG way from point and shoot. As integrated 360/VR video cameras come to market more and more, VR storytelling will become much more straightforward and the creators can focus more on the story.

Jeff Edson

And then delivery to what? There are many online platforms for 360/VR video playback today: Facebook, YouTube 360 and others for mobile headset viewing, and then there is delivery to a PC for non-mobile headset viewing. The viewing perspective is different for all of these, which means extra work to ensure continuity on all the platforms. To cover all possible viewers one needs to publish to all. This is not an optimal business model, which is really the crux of this issue.

Can standards help in this? Standards as we have known in the video world, yes and no. The standards for 360/VR video are happening by default, such as equirectangular and cubic formats, and delivery formats like H.264, Mov and more. Standards would help, but they are not the limiting factor for growth. The market is not waiting on a defined set of formats because demand for VR is quickly moving forward. People are busy creating.

What should clients ask of their production and post teams when embarking on their VR project?
We hear from our customers that the best results will come when the director, DP and post supervisor collaborate on the expectations for look and feel, as well as the possible creative challenges and resolutions. And experience and budget are big contributors. A key issue is, what camera/rig requirements are needed for your targeted platform(s)? For example, how many cameras and what type of cameras (4K, 6K, GoPro, etc.) as well as lighting? When what about sound, which plays a key role in the viewer’s VR experience.

This Yael Naim mini-concert was posted in Scratch VR by Alex Regeffe at Neotopy.

What is the biggest misconception about VR — content, process or anything relating to VR?
I see two. One: The perception that VR is a flash in the pan, just a fad. What we see today is just the launch pad. The applications for VR are vast within entertainment alone, and then there is the extensive list of other markets like training and learning in such fields as medical, military, online universities, flight, manufacturing and so forth. Two: That VR post production is a difficult process. There are too many steps and tools. This definitely doesn’t need to be the case. Our Scratch VR customers are getting high-quality results within a single, simplified VR workflow

How do we convince people this isn’t stereo 3D?
The main issue with stereo 3D is that it has really never scaled beyond a theater experience. Whereas with VR, it may end up being just the opposite. It’s unclear if VR can be a true theater experience other than classical technologies like domes and simulators. 360/VR video in the near term is, in general, a short-form media play. It’s clear that sooner than later smart phones will be able to shoot 360/VR video as a standard feature and usage will sky rocket overnight. And when that happens, the younger demographic will never shoot anything that is not 360. So the Snapchat/Instagram kinds of platforms will be filled with 360 snippets. VR headsets based upon mobile devices make the pure number of displays significant. The initial tethered devices are not insignificant in numbers, but with the next-generation of higher-resolution and untethered devices, maybe most significantly at a much lower price point, we will see the numbers become massive. None of this was ever the case with stereo 3D film/video.

Pixvana: Executive producer Aaron Rhodes

What is the biggest issue with VR productions at the moment? Is it lack of standards?
There are many issues with VR productions, many of them are just growing pains: not being able to see a live stitch, how to direct without being in the shot, what to do about lighting — but these are all part of the learning curve and evolution of VR as a craft. Resolution and management around big data are the biggest issues I see on the set. Pixvana is all about resolution — it plays a key role in better immersion. Many of the cameras out there only master at 4K and that just doesn’t cut it. But when they do shoot 8K and above, the data management is extreme. Don’t under estimate the responsibility you are giving to your DIT!

aaron rhodes

Aaron Rhodes

The biggest issue is this is early days for VR capture. We’re used to a century of 2D filmmaking and decade of high-definition capture with an assortment of camera gear. All current VR camera rigs have compromises, and will, until technology catches up. It’s too early for standards since we’re still learning and this space is changing rapidly. VR production and post also require different approaches. In some cases we have to unlearn what worked in standard 2D filmmaking.

What should clients ask of their production and post teams when embarking on their VR project?
Give me a schedule, and make it realistic. Stitching takes time, and unless you have a fleet of render nodes at your disposal, rendering your shot locally is going to take time — and everything you need to update or change it will take more time. VR post has lots in common with a non-VR spot, but the magnitude of data and rendering is much greater — make sure you plan for it.

Other questions to ask, because you really can’t ask enough:
• Why is this project being done as VR?
• Does the client have team members who understand the VR medium?
• If not will they be willing to work with a production team to design and execute with VR in mind?
• Has this project been designed for VR rather than just a 2D project in VR?
• Where will this be distributed? (Headsets? Which ones? YouTube? Facebook? Etc.)
• Will this require an app or will it be distributed to headsets through other channels?
• If it is an app, who will build the app and submit it to the VR stores?
• Do they want to future proof it by finishing greater than 4K?
• Is this to be mono or stereo? (If it’s stereo it better be very good stereo)
• What quality level are they aiming for? (Seamless stitches? Good stereo?)
• Is there time and budget to accomplish the quality they want?
• Is this to have spatialized audio?

What is the biggest misconception about VR — content, process or anything relating to VR?
VR is a narrative component, just like any actor or plot line. It’s not something that should just be done to do it. It should be purposeful to shoot VR. It’s the same with stereo. Don’t shoot stereo just because you can — sure, you can experiment and play (we need to do that always), but don’t without purpose. The medium of VR is not for every situation.
Other misconceptions because there are a lot out there:
• it’s as easy as shooting normal 2D.
• you need to have action going on constantly in 360 degrees.
• everything has to be in stereo.
• there are fixed rules.
• you can simply shoot with a VR camera and it will be interesting, without any idea of specific placement, story or design.
How do we convince people this isn’t stereo 3D?
Education. There are tiers of immersion with VR, and stereo 3D is one of them. I see these tiers starting with the desktop experience and going up in immersion from there, and it’s important to the strengths and weakness of each:
• YouTube/Facebook on the desktop [low immersion]
• Cardboard, GearVR, Daydream 2D/3D low-resolution
• Headset Rift and Vive 2D/3D 6 degrees of freedom [high immersion]
• Computer generated experiences [high immersion]

Maxon US: President/CEO Paul Babb

Paul Babb

What is the biggest issue with VR productions at the moment? Is it lack of standards?
Project file size. Huge files. Lots of pixels. Telling a story. How do you get the viewer to look where you want them to look? How do you tell and drive a story in a 360 environment.

What should clients ask of their production and post teams when embarking on their VR project?
I think it’s more that production teams are going to have to ask the questions to focus what clients want out of their VR. Too many companies just want to get into VR (buzz!) without knowing what they want to do, what they should do and what the goal of the piece is.

What is the biggest misconception about VR — content, process or anything relating to VR? How do we convince people this isn’t stereo 3D?
Oh boy. Let me tell you, that’s a tough one. People don’t even know that “3D” is really “stereography.”

Experience 360°: CEO Ryan Moore

What is the biggest issue with VR productions at the moment? Is it lack of standards?
One of the biggest issues plaguing the current VR production landscape is the lack of true professionals that exist in the field. While a vast majority of independent filmmakers are doing their best at adapting their current techniques, they have been unsuccessful in perceiving ryan moorehow films and VR experiences genuinely differ. This apparent lack of virtual understanding generally leads to poor UX creation within finalized VR products.

Given the novelty of virtual reality and 360 video, standards are only just being determined in terms of minimum quality and image specifications. These, however, are constantly changing. In order to keep a finger on the pulse, it is encouraged for VR companies to be plugged into 360 video communities through social media platforms. It is through this essential interaction that VR production technology can continually be reintroduced.

What should clients ask of their production and post teams when embarking on their VR project?
When first embarking on a VR project, it is highly beneficial to walk prospective clients through the entirety of the process, before production actually begins. This allows the client a full understanding of how the workflow is used, while also ensuring client satisfaction with the eventual partnership. It’s vital that production partners convey an ultimate understanding of VR and its use, and explain their tactics in “cutting” VR scenes in post — this can affect the user’s experience in a pronounced way.

‘The Backwoods Tennessee VR Experience’ via Experience 360.

What is the biggest misconception about VR — content, process or anything relating to VR? How do we convince people that this isn’t stereo 3D?
The biggest misconception about VR and 360 video is that it is an offshoot of traditional storytelling, and can be used in ways similar to both cinematic and documentary worlds. The mistake in the VR producer equating this connection is that it can often limit the potential of the user’s experience to that of a voyeur only. Content producers need to think much farther out of this box, and begin to embrace having images paired with interaction and interactivity. It helps to keep in mind that the intended user will feel as if these VR experiences are very personal to them, because they are usually isolated in a HMD when viewing the final product.

VR is being met with appropriate skepticism, and is widely still considered a ‘“fad” without the media landscape. This is often because the critic has not actually had a chance to try a virtual reality experience firsthand themselves, and does not understand the wide reaching potential of immersive media. At three years in, a majority of the adults in the United States have never had a chance to try VR themselves, relying on what they understand from TV commercials and online reviews. One of the best ways to convince a doubtful viewer is to give them a chance to try a VR headset themselves.

What is the biggest issue with VR productions at the moment? Is it lack of standards?
The biggest issue for us is (or was) probably stitching and the excessive amount of time it takes, but we’re tacking that head on with Project Loom. We have realtime stitching with Loom. You can already download an early version of it on GPUopen.com. But you’re correct, there is a lack of standards in VR/360 production. It’s mainly because there are no really established common practices. That’s to be expected though when you’re shooting for a new medium. Hollywood and entertainment professionals are showing up to the space in a big way, so I suspect we’ll all be working out lots of the common practices in 2017 on sets.

James Knight

What should clients ask of their production and post teams when embarking on their VR project?
Double check they have experience shooting 360 and ask them for a detailed post production pipeline outline. Occasionally, we hear horror stories of people awarding projects to companies that think they can shoot 360 without having personally explored 360 shooting themselves and making mistakes. You want to use an experienced crew that’s made the mistakes, and mostly is cognizant of what works and what doesn’t. The caveat there though is, again, there’s no established rules necessarily, so people should be willing to try new things… sometimes it takes someone not knowing they shouldn’t do something to discover something great, if that makes sense.

What is the biggest misconception about VR — content, process or anything relating to VR? How do we convince people this isn’t stereo 3D?
That’s a fun question. The overarching misconception for me, honestly, is just as though a cliché politician might, for example, make a fleeting judgment that video games are bad for society, people are often times making assumptions that VR if for kids or 16 year old boys at home in their boxer shorts. It isn’t. This young industry is really starting to build up a decent library of content, and the payoff is huge when you see well produced content! It’s transformative and you can genuinely envision the potential when you first put on a VR headset.

The biggest way to convince them this isn’t 3D is to convince a naysayer put the headset on… let’s agree we all look rather silly with a VR headset on, and once you get over that, you’ll find out what’s inside. It’s magical. I had the CEO of BAFTA LA, Chantal Rickards, tell me upon seeing VR for the first time, “I remember when my father had arrived home on Christmas Eve with a color TV set in the 1960s and the excitement that brought to me and my siblings. The thrill of seeing virtual reality for the first time was like seeing color TV for the first time, but times 100!”

Missing Pieces: Head of AR/VR/360 Catherine Day

Catherine Day

What is the biggest issue with VR productions at the moment?
The biggest issue with VR production today is the fact that everything keeps changing so quickly. Every day there’s a new camera, a new set of tools, a new proprietary technology and new formats to work with. It’s difficult to understand how all of these things work, and even harder to make them work together seamlessly in a deadline-driven production setting. So much of what is happening on the technology side of VR production is evolving very rapidly. Teams often reinvent the wheel from one project to the next as there are endless ways to tell stories in VR, and the workflows can differ wildly depending on the creative vision.

The lack of funding for creative content is also a huge issue. There’s ample funding to create in other mediums, and we need more great VR content to drive consumer adoption.

Is it lack of standards?
In any new medium and any pioneering phase of an industry, it’s dangerous to create standards too early. You don’t want to stifle people from trying new things. As an example, with our recent NBA VR project, we broke all of the conventional rules that exist around VR — there was a linear narrative, fast cut edits, it was over 25 minutes long — yet still was very well received. So it’s not a lack of standards, just a lack of bravery.

What should clients ask of their production and post teams when embarking on their VR project?
Ask to see what kind of work that team has done in the past. They should also delve in and find out exactly who completed the work and how much, if any, of it was outsourced. There is a curtain that often closes between the client and the production/post company and it closes once the work is awarded. Clients need to know who exactly is working on their project, as much of the legwork involved in creating a VR project — stitching, compositing etc. — is outsourced.

It’s also important to work with a very experienced post supervisor — one with a very discerning eye. You want someone who really knows VR that can evaluate every aspect of what a facility will assemble. Everything from stitching, compositing to editorial and color — the level of attention to detail and quality control for VR is paramount. This is key not only for current releases, but as technology evolves — and as new standards and formats are applied — you want your produced content to be as future-proofed as possible so that if it requires a re-render to accommodate a new, higher-res format in the future, it will still hold up and look fantastic.

What is the biggest misconception about VR — content, process or anything relating to VR?
On the consumer level, the biggest misconception is that people think that 360 video on YouTube or Facebook is VR. Another misconception is that regular filmmakers are the creative talents best suited to create VR content. Many of them are great at it, but traditional filmmakers have the luxury of being in control of everything, and in a VR production setting you have no box to work in and you have to think about a billion moving parts at once. So it either requires a creative that is good with improvisation, or a complete control freak with eyes in the back of their head. It’s been said before, but film and theater are as different as film and VR. Another misconception is that you can take any story and tell it in VR — you actually should only embark on telling stories in VR if they can, in some way, be elevated through the medium.

How do we convince people this isn’t stereo 3D?
With stereo 3D, there was no simple, affordable path for consumer adoption. We’re still getting there with VR, but today there are a number of options for consumers and soon enough there will be a demand for room-scale VR and more advanced immersive technologies in the home.


VR Audio: Virtual and spacial soundscapes

By Beth Marchant

The first things most people think of when starting out in VR is which 360-degree camera rig they need and what software is best for stitching. But virtual reality is not just a Gordian knot for production and post. Audio is as important — and complex — a component as the rest. In fact, audio designers, engineers and composers have been fascinated and challenged by VR’s potential for some time and, working alongside future-looking production facilities, are equally engaged in forging its future path. We talked to several industry pros on the front lines.

Howard Bowler

Music industry veteran and Hobo Audio founder Howard Bowler traces his interest in VR back to the groundbreaking film Avatar. “When that movie came out, I saw it three times in the same week,” he says. I was floored by the technology. It was the first time I felt like you weren’t just watching a film, but actually in the film.” As close to virtual reality as 3D films had gotten to that point, it was the blockbuster’s evolved process of motion capture and virtual cinematography that ultimately delivered its breathtaking result.

“Sonically it was extraordinary, but visually it was stunning as well,” he says. “As a result, I pressed everyone here at the studio to start buying 3D televisions, and you can see where that has gotten us — nowhere.” But a stepping stone in technology is more often a sturdy bridge, and Bowler was not discouraged. “I love my 3D TVs, and I truly believe my interest in that led me and the studio directly into VR-related projects.”

When discussing the kind of immersive technology Hobo Sound is involved with today, Bowler — like others interviewed for this series — clearly define VR’s parallel deliverables. “First, there’s 360 video, which is passive viewing, but still puts you in the center of the action. You just don’t interact with it. The second type, more truly immersive VR, lets you interact with the virtual environment as in a video game. The third area is augmented reality,” like the Pokemon Go phenomenon of projecting virtual objects and views onto your actual, natural environment. “It’s really important to know what you’re talking about when discussing these types of VR with clients, because there are big differences.”

With each segment comes related headsets, lenses and players. “Microsoft’s HoloLens, for example, operates solely in AR space,” says Hobo producer Jon Mackey. “It’s a headset, but will project anything that is digitally generated, either on the wall or to the space in front of you. True VR separates you from all that, and really good VR separates all your senses: your sight, your hearing and even touch and feeling, like some of those 4D rides at Disney World.” Which technology will triumph? “Some think VR will take it, and others think AR will have wider mass adoption,” says Mackey. “But we think it’s too early to decide between either one.”

Boxed Out

‘Boxed Out’ is a Hobo indie project about how gentrification is affecting artists studios in the Gowanus section of Brooklyn.

Those kinds of end-game obstacles are beside the point, says Bowler. “The main reason why we’re interested in VR right now is that the experiences, beyond the limitations of whatever headset you watch it on, are still mind-blowing. It gives you enough of a glimpse of the future that it’s incredible. There are all kinds of obstacles it presents just because it’s new technology, but from our point of view, we’ve honed it to make it pretty seamless. We’re digging past a lot of these problem areas, so at least from the user standpoint, it seems very easy. That’s our goal. Down the road, people from medical, education and training are going to need to understand VR for very productive reasons. And we’re positioning ourselves to be there on behalf of our clients.”

Hobo’s all-in commitment to VR has brought changes to its services as well. “Because VR is an emerging technology, we’re investing in it globally,” says Bowler. “Our company is expanding into complete production, from concepting — if the client needs it — to shooting, editing and doing all of the audio post. We have the longest experience in audio post, but we find that this is just such an exciting area that we wanted to embrace it completely. We believe in it and we believe this is where the future is going to be. Everybody here is completely on board to move this forward and sees its potential.”

To ramp up on the technology, Hobo teamed up with several local students who were studying at specialty schools. “As we expanded out, we got asked to work with a few production companies, including East Coast Digital and End of Era Productions, that are doing the video side of it. We’re bundling our services with them to provide a comprehensive set of services.” Hobo is also collaborating with Hidden Content, a VR production and post production company, to provide 360 audio for premium virtual reality content. Hidden Content’s clients include Samsung, 451 Media, Giant Step, PMK-BNC, Nokia and Popsugar.

There is still plenty of magic sauce in VR audio that continues to make it a very tricky part of the immersive experience, but Bowler and his team are engineering their way through it. “We’ve been developing a mixing technique that allows you to tie the audio to the actual object,” he says. “What that does is disrupt the normal stereo mix. Say you have a public speaker in the center of the room; normally that voice would turn with you in your headphones if you turn away from him. What we’re able to do is to tie the audio of the speaker to the actual object, so when you turn your head, it will pan to the right earphone. That also allows you to use audio as signaling devices in the storyline. If you want the viewer to look in a certain direction in the environment, you can use an audio cue to do that.”

Hobo engineer Diego Jimenez drove a lot of that innovation, says Mackey. “He’s a real VR aficionado and just explored a lot of the software and mixing techniques required to do audio in VR. We started out just doing a ton of tests and they all proved successful.” Jimenez was always driven by new inspiration, notes Bowler. “He’s certainly been leading our sound design efforts on a lot of fronts, from creating instruments to creating all sorts of unusual and original sounds. VR was just the natural next step for him, and for us. For example, one of the spots that we did recently was to create a music video and we had to create an otherworldly environment. And because we could use our VR mixing technology, we could also push the viewer right into the experience. It was otherworldly, but you were in that world. It’s an amazing feeling.”

boxed-out

‘Boxed Out’

What advice do Bowler and Mackey have for those interested in VR production and post? “360 video is to me the entry point to all other versions of immersive content,” says Bowler. “It’s the most basic, and it’s passive, like what we’re used to — television and film. But it’s also a completely undefined territory when it comes to production technique.” So what’s the way in? “You can draw on some of the older ways of doing productions,” he says, “but how do you storyboard in 360? Where does the director sit? How do you hide the crew? How do you light this stuff? All of these things have to be considered when creating 360 video. That also includes everyone on camera: all the viewer has to do is look around the virtual space to see what’s going on. You don’t want anything that takes the viewer out of that experience.”

Bowler thinks 360 video is also the perfect entry point to VR for marketers and advertisers creating branded VR content, and Hobo’s clients agree. “When we’ve suggested 360 video on certain projects and clients want to try it out, what that does is it allows the technology to breathe a little while it’s underwritten at the same time. It’s a good way to get the technology off the ground and also to let clients get their feet wet in it.”

Any studio or client contemplating VR, adds Mackey, should first find what works for them and develop an efficient workflow. “This is not really a solidified industry yet,” he says. “Nothing is standard, and everyone’s waiting to see who comes out on top and who falls by the wayside. What’s the file standard going to be? Or the export standard?  Will it be custom-made apps on (Google) YouTube or Facebook? We’ll see Facebook and Google battle it out in the near term. Facebook has recently acquired an audio company to help them produce audio in 360 for their video app and Google has the Daydream platform,” though neither platform’s codec is compatible with the other, he points out. “If you mix your audio to Facebook audio specs, you can actually have your audio come out in 360. For us, it’s been trial and error, where we’ve experimented with these different mixing techniques to see what fits and what works.”

Still, Bowler concedes, there is no true business yet in VR. “There are things happening and people getting things out there, but it’s still so early in the game. Sure, our clients are intrigued by it, but they are still a little mystified by what the return will be. I think this is just part of what happens when you deal with new technology. I still think it’s a very exciting area to be working in, and it wouldn’t surprise me if it doesn’t touch across many, many different subjects, from history to the arts to original content. Think about applications for geriatrics, with an aging population that gets less mobile but still wants to experience the Caribbean or our National Parks. The possibilities are endless.”

At one point, he admits, it may even become difficult to distinguish one’s real memory from one’s virtual memory. But is that really such a bad thing? “I’m already having this problem. I was watching an immersive video of Cuban music, that was pretty beautifully done, and by the end of the five-minute spot, I had the visceral experience that I was actually there. It’s just a very powerful way of experiencing content. Let me put it another way: 3D TVs were at the rabbit hole, and immersive video will take you down the rabbit hole into the other world.”

Source Sound
LA-based Source Sound, which has provided supervision and sound design on a number of Jaunt-produced cinematic VR experiences, including a virtual fashion show, a horror short and a Godzilla short film written and directed by Oscar-winning VFX artist Ian Hunter, as well as final Atmos audio mastering for the early immersive release Sir Paul McCartney Live, is ready for spacial mixes to come. That wasn’t initially the case.

Tim Gedemer

“When Jaunt first got into this space three years ago, they went to Dolby to try to figure out the audio component,” says Source Sound owner/supervising sound designer/editor Tim Gedemer. “I got a call from Dolby, who told me about what Jaunt was doing, and the first thing I said was, ‘I have no idea what you are talking about!’ Whatever it is, I thought, there’s really no budget and I was dragging my feet. But I asked them to show me exactly what they were doing. I was getting curious at that point.”

After meeting the team at Jaunt, who strapped some VR goggles on him and showed him some footage, Gedemer was hooked. “It couldn’t have been more than 30 seconds in and I was just blown away. I took off the headset and said, ‘What the hell is this?! We have to do this right now.’ They could have reached out to a lot of people, but I was thrilled that we were able to help them by seizing the moment.”

Gedemer says Source Sound’s business has expanded in multiple directions in the past few years, and VR is still a significant part of the studio’s revenue. “People are often surprised when I tell them VR counts for about 15-20 percent of our business today,” he says. “It could be a lot more, but we’d have to allocate the studios differently first.”

With a background in mixing and designing sound for film and gaming and theatrical trailers, Gedemer and his studio have a very focused definition of immersive experiences, and it all includes spacial audio. “Stereo 360 video with mono audio is not VR. For us, there’s cinematic, live-action VR, then straight-up game development that can easily migrate into a virtual reality world and, finally, VR for live broadcast.” Mass adoption of VR won’t happen, he believes, until enterprise and job training applications jump on the bandwagon with entertainment. “I think virtual reality may also be a stopover before we get to a world where augmented reality is commonplace. It makes more sense to me that we’ll just overlay all this content onto our regular days, instead of escaping from one isolated experience to the next.”

On set for the European launch of the Nokia Ozo VR camera in London, which featured a live musical performances captured in 360 VR.

For now, Source Sound’s VR work is completed in dedicated studios configured with gear for that purpose. “It doesn’t mean that we can’t migrate more into other studios, and we’re certainly evolving our systems to be dual-purpose,” he says. “About a year ago we were finally able to get a grip on the kinds of hardware and software we needed to really start coagulating this workflow. It was also clear from the beginning of our foray into VR that we needed to partner with manufacturers, like Dolby and Nokia. Both of those companies’ R&D divisions are on the front lines of VR in the cinematic and live broadcast space, with Dolby’s Atmos for VR and Nokia’s Ozo camera.”

What missing tools and technology have to be developed to achieve VR audio nirvana? “We delivered a wish list to Dolby, and I think we got about a quarter of the list,” he says. “But those guys have been awesome in helping us out. Still, it seems like just about every VR project that we do, we have to invent something to get us to the end. You definitely have to have an adventurous spirit if you want to play in this space.”

The work has already influenced his approach to more traditional audio projects, he says, and he now notices the lack of inter-spacial sound everywhere. “Everything out there is a boring rectangle of sound. It’s on my phone, on my TV, in the movie theater. I didn’t notice it as much before, but it really pops out at me now. The actual creative work of designing and mixing immersive sound has realigned the way I perceive it.”

VR Audio: What you need to know about Ambisonics

By Claudio Santos

The explosion of virtual reality as a new entertainment medium has been largely discussed in the filmmaking community in the past year, and there is still no consensus about what the future will hold for the technology. But regardless of the predictions, it is a fact that more and more virtual reality content is being created and various producers are experimenting to find just how the technology fits into the current market.

Out of the vast possibilities of virtual reality, there is one segment that is particularly close to us filmmakers, and that is 360 videos. They are becoming more and more popular on platforms such as YouTube and Facebook and present the distinct advantage that —  beside playing in VR headsets, such as the GearVR or the DayDream — these videos can also be played in standalone mobile phones, tablets and stationary desktops. This considerably expands the potential audience when compared to the relatively small group of people who own virtual reality headsets.

But simply making the image immerse the viewer into a 360 environment is not enough. Without accompanying spatial audio the illusion is very easily broken, and it becomes very difficult to cue the audience to look in the direction in which the main action of each moment is happening. While there are technically a few ways to design and implement spatial audio into a 360 video, I will share some thoughts and tips on how to work with Ambisonics, the spatial audio format chosen as the standard for platforms such as YouTube.

First, what is Ambisonics and why are we talking about it?
Ambisonics is a sound format that is slightly different from your usual stereo/surround paradigm because its channels are not attached to speakers. Instead, an Ambisonics recording actually represents the whole spherical soundfield around a point. In practice, it means that you can represent sound coming from all directions around a listening position and, using an appropriate decoder, you can playback the same recording in any set of speakers with any number of channels arranged around the listener horizontally or vertically. That is exactly why it is so interesting to us when we are working with spatial sound for VR.

The biggest challenge of VR audio is that you can’t predict which direction the viewer will be looking at in any given time. Using Ambisonics we can design the whole sound sphere and the VR player decodes the sound to match the direction of the video in realtime, decoding it into binaural for accurate headphone playback. The best part is that the decoding process is relatively light on processing power, which makes this a suitable option for mediums with limited resources such as smartphones.

In order to work with Ambisonics we have two options: to record the sound on location with an Ambisonics microphone, which gives us a very realistic representation of the sound in the location and is very well suited to ambiance recordings, for example; or we can encode other sound formats such as mono and stereo into Ambisonics and then manipulate the sound in the sphere from there, which gives us great flexibility in post production to use sound libraries and create interesting effects by carefully adjusting the positioning and width of a sound in the sphere.

Example: Mono “voice of God” placement. The left shows the soundfield completely filled, which gives the “in-head” illusion.

There are plenty of resources online explaining the technical nature of Ambisonics, and I definitely recommend reading them so you can better understand how to work with it and how the spatiality is achieved. But there aren’t many discussions yet about the creative decisions and techniques used in sound for 360 videos with Ambisonics, so that’s what we will be focusing on from now on.

What to do with mono “in-head” sources such as VO?
That was one of the first tricky challenges we found with Ambisonics. It is not exactly intuitive to place a sound source equally in all directions of the soundfield. The easiest solution comes more naturally once you understand how the four channels of the Ambisonics audio track interact with each other.

The first channel of the ambisonics audio, named W, is omnidirectional and contains the level information of the sound. The other three channels describe the position of the sound in the soundfield through phase relationships. Each one of the channels represents one dimension, which enables the positioning of sounds in three dimensions.

Now, if we want the sound to play at the same level and centered from every direction, what we want is for the sound source to be at the center of the soundfield “sphere,” where the listeners head is. In practice, that means that if you play the sound out of the first channel only, with no information into either of the other three channels, the sound will play “in-head.”

What to do with stereo non-diegetic music?
This is the natural question that follows the one of knowing what to do with mono sources. And the answer is a bit trickier. The mono, first channel trick doesn’t work perfectly with stereo sources because for that to work you would have to first sum the stereo to mono, which might be undesirable depending on your track.

If you want to maintain the stereo width of the source, one good option we found was to mirror the sound in two directions. Some plug-in suites, such as the Ambix VST, offer the functionality to mirror hemispheres of the soundfield. That could also be accomplish with careful positioning of a copy of the source, but this will make things easier.

Example of sound paced in the “left” of the soundfield in ambisonics.

Generally, what you want is to place the center of the stereo source in the focus of the action your audience will be looking at and mirror the top-bottom and the front-back. This will keep the music playing at the same level regardless of the direction the viewer looks at, but will keep the spatiality of the source. The downside is that the sound is not anchored to the viewer, so changes in direction of the sources will be noted as the viewer turns around, notably inverting the sides when looking at the back. I usually find this to be an interesting effect nonetheless, and it doesn’t distract the audience too much. If the directionality is too noticeable you can always mix a bit of the mono sum of the music into both channels in order to reduce the perceived width of the track.

How to creatively use reverberation in Ambisonics?
There is a lot you can do with reverberation in Ambisonics and this is only a single trick I find very useful when dealing with scenes in which you have one big obstacle in one direction (such as a wall), and no obstacles in the opposite direction.

In this situation, the sound would reflect from the barrier and return to the listener from one direction, while on the opposite side there would be no significant reflections because of the open field. You can simulate that by placing a slightly delayed reverb coming from the direction of the barrier only. You can adjust the width of the reflection sound to match the perceived size of the barrier and the delay based on the distance the barrier is from the viewer. In this case the effect usually works better with drier reverbs with defined early reflections but not a lot of late reflections.

Once you experiment with this technique you can use variations of if to simulate a variety of spaces and achieve even more realistic mixes that will fool anyone into believing the sounds you placed in post production were recorded on location.

Missing Pieces hires head of VR/AR/360, adds VR director

Production company Missing Pieces has been investing in VR recently by way of additional talent. Catherine Day has joined the studio as head of VR/AR/360. She was most recently at Jaunt VR where she was executive producer/head of unscripted. VR director Sam Smith has also joined the company as part of its VR directing team.

This bi-coastal studio has a nice body of VR under its belt. They are responsible for Dos Equis’ VR Masquerade and for bringing a president into VR with Bill Clinton’s Inside Impact series. They also created Follow My Lead: The Story of the NBA 2016 Finals, a VR sports documentary for the NBA and Oculus.

In her new role, Day (pictured) will drive VR/AR/360 efforts from the studio’s Los Angeles office and oversee several original VR series that will be announced jointly with WME and partners in the coming months. In her previous role at Jaunt VR, Day led projects for ABC News, RYOT/Huffington Post, Camp 4 Collective, XRez, Tastemade, Outside TV, Civic Nation and Conservation International.

VR director Smith is a CD and VR director who previously worked with MediaMonks on projects for Expedia, Delta, Converse and YT. Smith also has an extensive background in commercial visual effects. His has a deep understanding of post and VFX, which is helpful when developing VR/360 projects. He will also act as technical advisor.

Margarita Mix’s Pat Stoltz gives us the low-down on VR audio

By Randi Altman

Margarita Mix, one of Los Angeles’ long-standing audio and video post facilities, has taken on virtual reality with the addition of 360-degree sound rooms at their facilities in Santa Monica and Hollywood. This Fotokem company now offers sound design, mix and final print masters for VR video and remixing current spots for a full-surround environment.

Workflows for VR are new and developing every day — there is no real standard. So creatives are figuring it out as they go, but they can also learn from those who were early to the party, like Margarita Mix. They recently worked on a full-length VR concert film with the band Eagles of Death Metal and director/producer Art Haynie of Big Monkey Films. The band’s 2015 tour came to an abrupt end after playing the Bataclan concert hall during last year’s terrorist attacks in Paris. The film is expected to be available online and via apps shortly.

We reached out to Margarita Mix’s senior technical engineer, Pat Stoltz, to talk about his experience and see how the studio is tackling this growing segment of the industry.

Why was now the right time to open VR-dedicated suites?
VR/AR is an exciting emerging market and online streaming is a perfect delivery format, but VR pre-production, production and post is in its infancy. We are bringing sound design, editorial and mixing expertise to the next level based on our long history of industry-recognized work, and elevating audio for VR from a gaming platform to one suitable for the cinematic and advertising realms where VR content production is exploding.

What is the biggest difference between traditional audio post and audio post for VR?
Traditional cinematic audio has always played a very important part in support of the visuals. Sound effects, Foley, background ambiance, dialog and music clarity to set the mood have aided in pulling the viewer into the story. With VR and AR you are not just pulled into the story, you are in the story! Having the ability to accurately recreate the audio of the filmed environment through higher order ambisonics, or object-based mixing, is crucial. Audio does not only play an important part in support of the visuals, but is now a director’s tool to help draw the viewer’s gaze to what he or she wants the audience to experience. Audio for VR is a critical component of storytelling that needs to be considered early in the production process.

What is the question you asked the most from clients in terms of sound for VR?
Surprisingly none! VR/AR is so new that directors and producers are just figuring things out as they go. On a traditional production set, you have audio mixers and boom operators capturing audio on set. On a VR/AR set, there is no hiding. No boom operators or audio mixers can be visible capturing high-quality audio of the performance.

Some productions have relied on the onboard camera microphones. Unfortunately, in most cases, this turns out to be completely unusable. When the client gets all the way to the audio post, there is a realization that hidden wireless mics on all the actors would have yielded a better result. In VR especially, we recommend starting the sound consultation in pre-production, so that we can offer advice and guide decisions for the best quality product.

What question should clients ask before embarking on VR?
They should ask what they want the viewer to get out of the experience. In VR, no two people are going to walk away with the same viewing experience. We recommend staying focused on the major points that they would like the viewer to walk away with. They should then expand that to answer: What do I have to do in VR to drive that point home, not only mentally, but drawing their gaze for visual support? Based on the genre of the project, considerations should be made to “physically” pull the audience in the direction to tell the story best. It could be through visual stepping stones, narration or audio pre-cues, etc.

What tools are you using on VR projects?
Because this is a nascent field, new tools are becoming available by the day, and we assess and use the best option for achieving the highest quality. To properly address this question, we ask: Where is your project going to be viewed? If the content is going to be distributed via a general Web streaming site, then it will need to be delivered in that audio file format.

There are numerous companies writing plug-ins that are quite good to deliver these formats. If you will be delivering to a Dolby VR (object-based preparatory format) supported site, such as Jaunt, then you will need to generate the proper audio file for that platform. Facebook (higher order ambisonics) requires even a different format. We are currently working in all these formats, as well as working closely with leaders in VR sound to create and test new workflows and guide developments in this new frontier.

What’s the one thing you think everyone should know about working and viewing VR?
As we go through life, we each have our own experiences or what we choose to experience. Our frame of reference directs our focus on things that are most interesting to us. Putting on VR goggles, the individual becomes the director. The wonderful thing about VR is now you can take that individual anywhere they want to go… both in this world and out of it. Directors and producers should think about how much can be packed into a story to draw people into the endless ways they perceive their world.
