Hi there,
This feature is not included in the Live version. If you'd like to try it out, please manually switch to the beta version.
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 update.
After open a passthrough video, you just need to 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.
