There are not very many video formats (codecs) that support alpha channels. Most that do were not intended for use on the web. As far as I understand, in order for Hubs to support this type of format, there would need to be an extension to glTF to allow it. Also, three.js would need to support rendering the format, which it may already.
We've been asked a lot recently if it is possible to add a video with an alpha channel to Hubs rooms (e.g. https://twitter.com/tartanski/status/1302686272750788608 , https://discordapp.com/channels/498741086295031808/535638724785078292/750734367034441880, https://github.com/mozilla/hubs/discussions/2719 ). Currently there is just have a black background where the alpha channel appears.
A community member mentioned that Alpha webm files used to work in Hubs, but no longer do.
