New AMD Radeon Pro Duo graphics card for pro workflows

AMD was at NAB this year with its dual-GPU graphics card designed for pros — the Polaris-architecture-based Radeon Pro Duo. Built on the capabilities of the Radeon Pro WX 7100, the Radeon Pro Duo graphics card is designed for media and entertainment, broadcast and design workflows.

The Radeon Pro Duo is equipped with 32GB of ultra-fast GDDR5 memory to handle larger data sets, more intricate 3D models, higher-resolution videos and complex assemblies. Operating at a max power of 250W, the Radeon Pro Duo uses a total of 72 compute units (4,608 stream processors) for a combined performance of up to 11.45 TFLOPS of single-precision compute performance on one board, and twice the geometry throughput of the Radeon Pro WX 7100.

The Radeon Pro Duo enables pros to work on up to four 4K monitors at 60Hz, drive the latest 8K single monitor display at 30Hz using a single cable or drive an 8K display at 60Hz using a dual cable solution.

The Radeon Pro Duo’s distinct dual-GPU design allows pros the flexibility to divide their workloads, enabling smooth multi-tasking between applications by committing GPU resources to each. This will allow users to focus on their creativity and get more done faster, allowing for a greater number of design iterations in the same time.

On select pro apps (including DaVinci Resolve, Nuke/Care VR, Blender Cycles and VRed), the Radeon Pro Duo offers up to two times faster performance compared with the Radeon Pro WX 7100.

For those working in VR, the Radeon Pro Duo graphics card uses the power of two GPUs to render out separate images for each eye, increasing VR performance over single GPU solutions by up to 50% in the SteamVR test. AMD’s LiquidVR technologies are also supported by the industry’s leading realtime engines, including Unity and Unreal, to help ensure smooth, comfortable and responsive VR experiences on Radeon Pro Duo.

The Radeon Pro Duo’s planned availability is the end of May at an expected price of US $999.

Hobo’s Howard Bowler and Jon Mackey on embracing full-service VR

By Randi Altman

New York-based audio post house Hobo, which offers sound design, original music composition and audio mixing, recently embraced virtual reality by launching a 360 VR division. Wanting to offer clients a full-service solution, they partnered with New York production/post production studios East Coast Digital and Hidden Content, allowing them to provide concepting through production, post, music and final audio mix in an immersive 360 format.

The studio is already working on some VR projects, using their “object-oriented audio mix” skills to enhance the 360 viewing experience.

We touched base with Hobo’s founder/president, Howard Bowler, and post production producer Jon Mackey to get more info on their foray into VR.

Why was now the right time to embrace 360 VR?
Bowler: We saw the opportunity stemming from the advancement of the technology not only in the headsets but also in the tools necessary to mix and sound design in a 360-degree environment. The great thing about VR is that we have many innovative companies trying to establish what the workflow norm will be in the years to come. We want to be on the cusp of those discoveries to test and deploy these tools as the ecosystem of VR expands.

As an audio shop you could have just offered audio-for-VR services only, but instead aligned with two other companies to provide a full-service experience. Why was that important?
Bowler: This partnership provides our clients with added security when venturing out into VR production. Since the medium is relatively new in the advertising and film world, partnering with experienced production companies gives us the opportunity to better understand the nuances of filming in VR.

How does that relationship work? Will you be collaborating remotely? Same location?
Bowler: Thankfully, we are all based in West Midtown, so the collaboration will be seamless.

Can you talk a bit about object-based audio mixing and its challenges?
Mackey: The challenge of object-based mixing is not only mixing based in a 360-degree environment or converting traditional audio into something that moves with the viewer but determining which objects will lead the viewer, with its sound cue, into another part of the environment.

Bowler: It’s the creative challenge that inspires us in our sound design. With traditional 2D film, the editor controls what you see with their cuts. With VR, the partnership between sight and sound becomes much more important.

Howard Bowler pictured embracing VR.

How different is your workflow — traditional broadcast or spot work versus VR/360?
Mackey: The VR/360 workflow isn’t much different than traditional spot work. It’s the testing and review that is a game changer. Things generally can’t be reviewed live unless you have a custom rig that runs its own headset. It’s a lot of trial and error in checking the mixes, sound design, and spacial mixes. You also have to take into account the extra time and instruction for your clients to review a project.

What has surprised you the most about working in this new realm?
Bowler: The great thing about the VR/360 space is the amount of opportunity there is. What surprised us the most is the passion of all the companies that are venturing into this area. It’s different than talking about conventional film or advertising; there’s a new spark and its fueling the rise of the industry and allowing larger companies to connect with smaller ones to create an atmosphere where passion is the only thing that counts.

What tools are you using for this type of work?
Mackey: The audio tools we use are the ones that best fit into our Avid ProTools workflow. This includes plug-ins from G-Audio and others that we are experimenting with.

Can you talk about some recent projects?
Bowler: We’ve completed projects for Samsung with East Coast Digital, and there are more on the way.

The importance of audio in VR

By Anne Jimkes

While some might not be aware, sound is 50 percent of the experience in VR, as well as in film, television and games. Because we can’t physically see the audio, it might not get as much attention as the visual side of the medium. But the balance and collaboration between visual and aural is what creates the most effective, immersive and successful experience.

More specifically, sound in VR can be used to ease people into the experience, what we also call “on boarding.” It can be used subtly and subconsciously to guide viewers by motivating them to look in a specific direction of the virtual world, which completely surrounds them.

In every production process, it is important to discuss how sound can be used to benefit the storytelling and the overall experience of the final project. In VR, especially the many low-budget independent projects, it is crucial to keep the importance and use of audio in mind from the start to save time and money in the end. Oftentimes, there are no real opportunities or means to record ADR after a live-action VR shoot, so it is important to give the production mixer ample opportunity to capture the best production sound possible.

This involves capturing wild lines, making sure there is time to plant and check the mics, and recording room tone. Things that are already required, albeit not always granted, on regular shoots, but even more important on a set where a boom operator cannot be used due to the 360 degree view of the camera. The post process is also very similar to that for TV or film up to the point of actual spatialization. We come across similar issues of having to clean up dialogue and fill in the world through sound. What producers must be aware of, however, is that after all the necessary elements of the soundtrack have been prepared, we have to manually and meticulously place and move around all the “audio objects” and various audio sources throughout the space. Whenever people decide to re-orient the video — meaning when they change what is considered the initial point of facing forward or “north” — we have to rewrite all this information that established the location and movement of the sound, which takes time.

Capturing Audio for VR
To capture audio for virtual reality we have learned a lot about planting and hiding mics as efficiently as possible. Unlike regular productions, it is not possible to use a boom mic, which tends to be the primary and most naturally sounding microphone. Aside from the more common lavalier mics, we also use ambisonic mics, which capture a full sphere of audio and matches the 360 picture — if the mic is placed correctly on axis with the camera. Most of the time we work with Sennheiser and use their Ambeo microphone to capture 360 audio on set, after which we add the rest of the spatialized audio during post production. Playing back the spatialized audio has become easier lately, because more and more platforms and VR apps accept some form of 360 audio playback. There is still a difference between the file formats to which we can encode our audio outputs, meaning that some are more precise and others are a little more blurry regarding spatialization. With VR, there is not yet a standard for deliverables and specs, unlike the film/television workflow.

What matters most in the end is that people are aware of how the creative use of sound can enhance their experience, and how important it is to spend time on capturing good dialogue on set.

Timecode’s new firmware paves the way for VR

Timecode Systems, which makes wireless technologies for sharing timecode and metadata, has launched a firmware upgrade that enhances the accuracy of its wireless genlock.

Promising sub-line-accurate synchronization, the system allows Timecode Systems products to stay locked in sync more accurately, setting the scene for development of a wireless sensor sync solution able to meet the requirements of VR/AR and motion capture.

“The industry benchmark for synchronization has always been ‘frame-accurate’, but as we started exploring the absolutely mission-critical sync requirements of virtual reality, augmented reality and motion capture, we realized sync had to be even tighter,” said Ashok Savdharia, chief technical officer at Timecode Systems. “With the new firmware and FPGA algorithms released in our latest update, we’ve created a system offering wireless genlock to sub-line accuracy. We now have a solid foundation on which to build a robust and immensely accurate genlock, HSYNC and VSYNC solution that will meet the demands of VR and motion capture.”

A veteran in camera and image sensor technology, Savdharia joined Timecode Systems last year. In addition to building up the company’s multi-camera range of solutions, he is leading a development team to pioneering a wireless sync system for the VR and motion capture market.

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.

VR Post: Hybrid workflows are key

By Beth Marchant

Shooting immersive content is one thing, but posting it for an ever-changing set of players and headsets is whole other multidimensional can of beans.

With early help from software companies that have developed off-the-shelf ways to tackle VR post — and global improvements to their storage and networking infrastructures — some facilities are diving into immersive content by adapting their existing post suites with a hybrid set of new tools. As with everything else in this business, it’s an ongoing challenge to stay one step ahead.

Chris Healer

The Molecule
New York- and Los Angeles-based motion graphics and VFX post house The Molecule leapt into the VR space more than a year and a half ago when it fused The Foundry’s Nuke with the open-sourced panoramic photo stitching software Hugin. Then, CEO Chris Healer took the workflow one step further. He developed an algorithm that rendered stereoscopic motion graphics spherically in Nuke.

Today, those developments have evolved into a robust pipeline that fuels The Molecule’s work for Conan O’Brien’s eponymous TBS talk show, The New York Times’s VR division and commercial work. “It’s basically eight or ten individual nodes inside Nuke that complete one step or another of the process,” says Healer. “Some of them overlap with Cara VR,” The Foundry’s recently launched VR plug-in for Nuke, “but all of it works really well for our artists. I talk to The Foundry from time to time and show them the tools, so there’s definitely an open conversation there about what we all need to move VR post forward.”

Collaborating with VR production companies like SuperSphere, Jaunt and Pixvana in Seattle, The Molecule is heading first where mass VR adoption seems likeliest. “The New York Times, for example, wants to have a presence at film festivals and new technology venues, and is trying to get out of the news-only business and into the entertainment-provider business. And the job for Conan was pretty wild — we had to create a one-off gag for Comic-Con that people would watch once and go away laughing to the next thing. It’s kind of a cool format.”

Healer’s team spent six weeks on the three-minute spot. “We had to shoot plates, model characters, animate them, composite it, build a game engine around it, compile it, get approval and iterate through that until we finished. We delivered 20 or so precise clips that fit into a game engine design, and I think it looks great.”

Healer says the VR content The Molecule is posting now is, like the Conan job, a slight variation on more typical recent VR productions. “I think that’s also what makes VR so exciting and challenging right now,” he says. “Everyone’s got a different idea about how to take it to the next level. And a lot of that is in anticipation of AR (augmented reality) and next-generation players/apps and headsets.

‘Conan’

The Steam store,” the premiere place online to find virtual content, “has content that supports multiple headsets, but not all of them.” He believes that will soon gel into a more unified device driver structure, “so that it’s just VR, not Oculus VR or Vive VR. Once you get basic head tracking together, then there’s the whole next thing: Do you have a controller of some kind, are you tracking in positional space, do you need to do room set up? Do we want wands or joysticks or hand gestures, or will keyboards do fine? What is the thing that wins? Those hurdles should solidify in the next year or two. The key factor in any of that is killer content.”

The biggest challenge facing his facility, and anyone doing VR post right now, he says, is keeping pace with changing resolutions and standards. “It used to be that 4K or 4K stereo was a good deliverable and that would work,” says Healer. “Now everything is 8K or 10K, because there’s this idea that we also have to future-proof content and prepare for next-gen headsets. You end up with a lot of new variables, like frame rate and resolution. We’re working on stereo commercial right now, and just getting the footage of one shot converted from only six cameras takes almost 3TB of disk space, and that’s just the raw footage.”

When every client suddenly wants to dip their toes into VR, how does a post facility respond? Healer thinks the onus is on production and post services to provide as many options as possible while using their expertise to blaze new paths. “It’s great that everyone wants to experiment in the space, and that puts a certain creative question in our field,” he says. “You have to seriously ask of every project now, does it really just need to be plain-old video? Or is there a game component or interactive component that involves video? We have to explore that. But that means you have to allocate more time in Unity https://unity3d.com/ building out different concepts for how to present these stories.”

As the client projects get more creative, The Molecule is relying on traditional VFX processes like greenscreen, 3D tracking and shooting plates to solve VR-related problems. “These VFX techniques help us get around a lot of the production issues VR presents. If you’re shooting on a greenscreen, you don’t need a 360 lens, and that helps. You can shoot one person walking around on a stage and then just pan to follow them. That’s one piece of footage that you then composite into some other frame, as opposed to getting that person out there on the day, trying to get their performance right and then worrying about hiding all the other camera junk. Our expertise in VFX definitely gives us an advantage in VR post.”

From a post perspective, Healer still hopes most for new camera technology that would radically simplify the stitching process, allowing more time for concepting and innovative project development. “I just saw a prototype of a toric lens,” shaped like the donut-like torus that results from revolving a circle in three-dimensional space, “that films 360 minus a little patch, where the tripod is, in a single frame,” he says. “That would be huge for us. That would really change the workflow around, and while we’re doing a lot of CG stuff that has to be added to VR, stitching takes the most time. Obviously, I care most about post, but there are also lots of production issues around a new lens like that. You’d need a lot of light to make it work well.”

Local Hero Post
For longtime Scratch users Local Hero Post, in Santa Monica, the move to begin grading and compositing in Assimilate Scratch VR was a no-brainer. “We were one of the very first American companies to own a Scratch when it was $75,000 a license,” says founder and head of imaging Leandro Marini. “That was about 10 years ago and we’ve since done about 175 feature film DIs entirely in Scratch, and although we also now use a variety of tools, we still use it.”

Leandro Marini

Marini says he started seeing client demand for VR projects about two years ago and he turned to Scratch VR. He says it allows users do traditional post the way editors and colorist are used to — with all the same DI tools that let you do complicated paint outs, visual effects and 50-layer-deep color corrections, Power Windows, in realtime on a VR sphere.”

New Deal Studios’ 2015 Sundance film, Kaiju Fury was an early project, “when Scratch VR was first really user-friendly and working in realtime.” Now Marini says their VR workflow is “pretty robust. [It’s] currently the only system that I know of that can work in VR in realtime in multiple ways,” which includes a echo-rectangular projection, which gives you a YouTube 360-type of feel and an Oculus headset view.

“You can attach the headset, put the Oculus on and grade and do visual effects in the headset,” he says. “To me, that’s the crux: you really have to be able to work inside the headset if you are going to grade and do VR for real. The difference between seeing a 360 video on a computer screen and seeing it from within a headset and being able to move your head around is huge. Those headsets have wildly different colors than a computer screen.”

The facility’s — and likely the industry’s — highest profile and biggest budget project to date is Invisible, a new VR scripted miniseries directed by Doug Liman and created by 30 Ninjas, the VR company he founded with Julina Tatlock. Invisible premiered in October on Samsung VR and the Jaunt app and will roll out in coming months in VR theaters nationwide. Written by Dallas Buyers Club screenwriter Melisa Wallack and produced by Jaunt and Condé Nast Entertainment, it is billed as the first virtual reality action-adventure series of its kind.

‘Invisible’

“Working on that was a pretty magical experience,” says Marini. “Even the producers and Liman himself had never seen anything like being able to do the grade, do VFX and do composite and stereo fixes in 3D virtual reality all with the headset on. That was our initial dilemma for this project, until we figured it out: do you make it look good for the headset, for the computer screen or for iPhones or Samsung phones? Everyone who worked on this understood that every VR project we do now is in anticipation of the future wave of VR headsets. All we knew was that about a third would probably see it on a Samsung Gear VR, another third would see it on a platform like YouTube 360 and the final third would see it on some other headset like Oculus Rift, HTC or Google’s new Daydream.”

How do you develop a grading workflow that fits all of the above? “This was a real tricky one,” admits Marini. “It’s a very dark and moody film and he wanted to make a family drama thriller within that context. A lot of it is dark hallways and shadows and people in silhouette, and we had to sort of learn the language a bit.”

Marini and his team began exclusively grading in the headset, but that was way too dark on computer monitors. “At the end of the day, we learned to dial it back a bit and make pretty conservative grades that worked on every platform so that it looked good everywhere. The effect of the headset is it’s a light that’s shining right into your eyeball, so it just looks a lot brighter. It had to still look moody inside the headset in a dark room but not too moody that it vanishes on computer laptop in a bright room. It was a balancing act.”

Local Hero

Local Hero also had to figure out how to juggle the new VR work with its regular DI workload. “We had to break off the VR services into a separate bay and room that is completely dedicated to it,” he explains. “We had to slice it off from the main pipeline because it needs around-the-clock custom attention. Very quickly we realized we needed to quarantine this workflow. One of our colorists here has become a VR expert, and he’s now the only one allowed to grade those projects.” The facility upgraded to a Silverdraft Demon workstation with specialized storage to meet the exponential demand for processing power and disk space.

Marini says Invisible, like the other VR work Local Hero has done before is, in essence, a research project in these early days of immersive content. “There is no standard color space or headset or camera. And we’re still in the prototype phase of this. While we are in this phase, everything is an experiment. The experience of being in 3D space is interesting but the quality of what you’re watching is still very, very low resolution. The color fidelity relative to what we’re used to in the theater and on 4K HDR televisions is like VHS 1980’s quality. We’re still very far away from truly excellent VR.”

Scratch VR workflows in Invisible included a variety of complicated processes. “We did things like dimension-alizing 2D shots,” says Marini. “That’s complicated stuff. In 3D with the headset on we would take a shot that was in 2D, draw a rough roto mask around the person, create a 3D field, pull their nose forward, push their eyes back, push the sky back — all in a matter of seconds. That is next-level stuff for VR post.”

Local Hero also used Scratch Web for reviews. “Moments after we finished a shot or sequence it was online and someone could put on a headset and watch it. That was hugely helpful. Doug was in London, Condé Nast in New York. Lexus was a sponsor of this, so their agency in New York was also involved. Jaunt is down the street from us here in Santa Monica. And there were three clients in the bay with us at all times.”

‘Invisible’

As such, there is no way to standardize a VR DI workflow, he says. “For Invisible, it was definitely all hands on deck and every day was a new challenge. It was 4K 60p stereo, so the amount of data we had to push — 4K 60p to both eyes — which was unprecedented.” Strange stereo artifacts would appear for no apparent reason. “A bulge would suddenly show up on a wall and we’d have to go in there and figure out why and fix it. Do we warp it? Try something else? It was like that throughout the entire project: invent the workflow every day and fudge your way through. But that’s the nature of experimental technology.”

Will there be a watershed VR moment in the year ahead? “I think it all depends on the headsets, which are going to be like mobile phones,” he says. “Every six months there will be a new group of them that will be better and more powerful with higher resolution. I don’t think there will be a point in the future when everyone has a self-contained high-end headset. I think the more affordable headsets that you put your phone into, like Gear VR and Daydream, are the way most people will begin to experience VR. And we’re only 20 percent of the way there now. The whole idea of VR narrative content is completely unknown and it remains to be seen if audiences care and want it and will clamor for it. When they do, then we’ll develop a healthy VR content industry in Hollywood.”

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.

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!

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.

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.

Radeon Technologies Group at AMD: Head of VR James Knight

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.
