View VR Resolutions & Output Specifications
The VR community is still working out best practices for resolution and output of VR content. In most cases the best option depends on the target head-mounted display or delivery mechanism. HMDs based on mobile devices (Cardboard, GearVR) tend to favor 16:9 aspect ratio, typically at UHD (3840x2160), because the hardware decoders on these devices max out at UHD resolution. Computer-based HMDs offer a lot more flexibility, but there’s not yet standard playback & delivery applications.
Below are some examples based on our research and testing:
YouTube
Because YouTube re-compresses uploaded content in multiple 16:9 resolutions with a max supported resolution of 3840x2160, best results are achieved by always using all the pixels YouTube will allow.
All 360 and VR video for YouTube must have metadata injected in the final mp4 using the provided tool.
Mono:
- Equirectangular
- 3840x2160
- 60 fps
- 150 mbps Constant
Stereo:
- Omni-Directional Stereo
- 3840x2160 (3840x1080 each eye, arranged top-bottom)
- 60 fps
