Transcript of VR Video

2011
VR video has evolved rapidly over the past few years.
Pioneers & Innovators
Because 360 video is a true convergence technology, no one individual or organization can claim to have invented it. Here is a list of some notable innovators and leaders currently in the field.
Types of 360 Video
Complexity varies from simple capture/display to highly speculative and experimental technology.
"Flat" 360
What's Next?
180 Degree Video may emerge as a dominant format for several reasons:
VR° Video Basics

less complex
"Flat" 360 Capture & Display Methods
Display is possible on proprietary and open source viewers such as VRplayer
more complex
Generally, a 360 degree video file that contains no depth information and is delivered to the viewer in a traditional, standard flat video format (HD, 4K, etc.)
Producers are rushing to create content with a wide range of techniques and results.
This exciting new medium presents unique challenges and opportunities.
Play the presentation to learn more (it takes about 4 minutes), or pause and click on specific topics at your leisure!
SUMMARY
Stereo 360
Stereo 360 degree video captures separate streams for the left and right eyes, allowing stereoscopic playback and the illusion of 3D. This format requires a proprietary playback mechanism.
Light Field Technology
Revolutionary convergence technology utilizing light fields is currently in development. Miniaturization, low cost and high-speed computation combine to create highly realistic interpretations of the visual environment.

@davebondi
"Flat" 360


Uses established, standardized formats
Wide variety of commercially available production tools
Can be inexpensively produced
Many options for distribution
Stereo 360 Capture & Display Methods
An array of stereo camera pairs capture separate left and right eye views
Non-standard video data must be processed and formatted for a specific playback mechanism
Non-stereo capture can sometimes be post-processed into stereo streams
Video is played back using proprietary software
Light Field Capture & Display Methods
Microlens arrays capture photon trajectories from millions of simultaneous directions
Three dimensional space data is rapidly extrapolated and analyzed
3D environment data may be augmented or completely replaced
The photon data is projected back directly into the viewer's eyes via microscopic projector/lens arrays
Pros
Cons
Content quality can be very poor
No depth perception - video is displayed on a flat dome or cube at a fixed distance to the viewer
Requires large datasets, but with compression, artifacts become more prominent
2 or more cameras in an array
Single camera shooting a reflective chrome surface
Images are either post-processed or stitched during recording, depending on equipment
Youtube offers playback for a wide variety of formats
Stereo 360


Much greater sense of realism and depth
Pioneers may establish methods and products that a fledgling industry will adopt
Producers have exclusive control of playback technology
Pros
Cons
Expensive - requires proprietary hardware and software
Stitching algorithms are complex
Can never be perfectly stereo because of capture methodologies
Most of the current tools will soon be obsolete
Light Field Capture


Extremely accurate representation of visual environment
Captured data can be manipulated in novel ways
Core technical assumptions have been tested through decades of research
Applications of tech are extremely broad
Pros
Cons
Human factors remain unknown
Hardware standards have not been consolidated into a consumer device
Potentially disruptive to established industries
Content creation pipelines are experimental
Other unknown consequences
