IBC Report: Making high-resolution panoramic video

By Tom Coughlin

Higher resolution content is becoming the norm in today’s media workflows, but pixel count is not the only element that is changing. In addition to the pixel density the depth of image, color gamut, frame rates and even the number of simultaneous streams of video will be important. At the 2015 IBC in Amsterdam there was a clear picture of a future that includes UHD 4K and 8K video, as well as virtual reality, as the future path to more immersive video and entertainment experiences.

NHK, a pioneer in 8K video hardware and infrastructure development has given more details on its introduction of this higher resolution format. They will start test broadcasts of their 8K technology in 2016, followed by significant satellite video transmission in 2018 and widespread deployment in 2020 in time for the Tokyo Olympic Games. The company is looking at using HEVC compression to put a 72Gb/s video stream with 22:2 channel audio into a 100Mb/s delivery channel.

In the Technology Zone at the IBC there were displays of virtual reality, 8K video developments, (mostly by NHK), as well as multiple camera set-ups for creating virtual reality video and various ways to use panoramic video. Sphericam 2 is a Kickstarter-funded product that provides 60 frames per second 4K video capture for creating VR content. This six-camera device is compact and can be placed on a stick and used like a selfie camera to capture a 360-degree view.

At the 2015 Google Developers Conference, GoPro demonstrated a 360-degree camera rig (our main image) using 16 GoPro cameras to capture panoramic video. At the IBC, GoPro displayed a more compact 360 Hero six-camera rig for 3D video capture.

In the Technology Zone, Al Jeezera had an eight-camera rig for 4K video capture (made using a 3D printer) and were using software to create panoramic videos. There are many such videos on YouTube that can be viewed as panoramic videos, which change perspective when viewed on a smart phone that has an accelerometer that will create a reference around which the viewer can look at the panoramic activities. The Kolor software actually provides a number of different ways to view the captured content.

While many viewing devices for VR video use special split-screen displays, or even use smart phones with a split screen image while using the phone’s accelerometers to give the sense of being surrounded by the viewed image — like the Google Cardboard — there are other ways to create an immersive experience. As mentioned earlier, panoramic videos with a single (or split screen) are available on YouTube. There are also spherical display devices where the still or video image can be rotated by moving your hand across the sphere like the one shown below.

Higher resolution content is becoming mainstream, with 4K TVs set to be the majority that are sold within the next few years. 8K video production, pioneered by NHK and others in Japan, could be the next 4K video by the start of the next decade, driving even more realistic content capture and higher bandwidth and higher storage capacity post.

Multi-camera content is also growing in popularity to support virtual reality games and other applications. This growth is enabled by the proliferation of low cost, high-resolution cameras and sophisticated software that combine the video from these cameras to create a panoramic video and virtual reality experience.

The trends toward higher resolution, combined with a greater color gamut, higher frame rate and color depth will transform video experiences by the next decade, leading to new requirements for storage, networking and processing in video production and display.

Cinematic pro camera system for VR from Jaunt

Jaunt, a company focusing on content for virtual reality, has launched a series of professional-grade camera systems designed for capturing fully immersive 360-degree cinematic VR experiences. The new Neo series facilitates high-quality, high-resolution capture using custom optics designed for 3D light-field capture, large-format sensors with superior low-light performance and a fully synchronized global shutter sensor array.

Neo offers turn-on-and-shoot simplicity for capturing spontaneous events while also providing full manual control. In addition to 360-degree capture, the camera system supports high dynamic range (HDR) imaging, as well as timelapse and high frame rate (HFR) capture. It features a 360-degree industrial, design by Lunar, and housed in a compact and weatherproof form factor, Neo offers an extensive tool set for configuration, rendering and asset management.

According to CTO Arthur van Hoff, “We have been experimenting with off-the-shelf components for the past two years, and we have learned a lot. The Neo camera is the result of this research and fixes many of the challenges that we encountered. It allows us to produce high-quality cinematic VR experiences reliably and quickly.”

Van Hoff went on to say that thanks to their own camera, the company “will be able to record in more situations that were previously challenging because of bad lighting or fast motion. It will greatly reduce the post production cost of VR experiences by providing higher quality captured data.”

The first Neo camera systems will be available to partners in August 2015, with production to scale up later this year. With the Neo camera system, Jaunt Studios, which was launched in May and develops and produces cinematic VR experiences in collaboration with creative filmmakers, will scale up production of professional-grade VR content.
