Vimeo OTT is able to support 4K/HDR videos. As long as the device you're playing on supports 4K, 4K playback is supported on the web and the following branded apps:
- Android TV
- Fire TV
We're still working on supporting 4K/HDR on iOS, tvOS, Roku, Xbox One, and Tizen TV. 4K/HDR is not presently supported on these branded apps at this time.
As for 360 and VR, we don't support this on Vimeo OTT just yet. Alternatively, you could always upload the 4K, 360, or VR videos in a zip folder and add it to your Product as an Extra.
