Hello,
Please follow the steps below to update to the beta version first.
On your Quest 2 or Quest 3, go to Quest Settings > Privacy & safety > Installed app > find SKYBOX VR Video Player > click Release Channels > select "2.0.0 Preview" and install the beta update.
To watch passthrough videos, you just need to open a passthrough video, click "Advanced Settings" and enable the "Passthrough Video" toggle. Then SKYBOX will remove the background from a scene using Chroma Key Passthrough or Alpha Channel Passthrough.
It's a feature that attempts to automatically detect and remove the background of a video, rather than allowing you to manually specify a color to remove.
Hope it helps. Let us know if you have other questions.
