So I’m trying to embed video files with alpha channels for a presentation. I ran a test where I included a webm file over some live text. I previewed it as a presentation and it worked perfectly. I sent it to my manager to reveiw and when he looked at it the alpha channel was replaced w/ a black background and a white box around that content that’d previously been over transparency.
Is Figma re-encoding my file? If so it’s doing it wrong. If not, why is the video changing after a period of time?

I’m having the same issue; minutes after initial upload, the alpha channel of my videos is replaced by black background.
It would be so nice to be able to work with transparent videos in Figma

Also getting the same issue with webM recently. Occurs in Present mode when playing, looks fine in Design mode while static.
I was told by a Figma rep that they don’t plan on fixing this because safari doesn’t support webm v9 w/ transparency. This seems silly because that’s only on mobile. Also the issue is with figma’s re-compression of uploaded webm. it works fine initially but breaks after they come in and incorrectly re-compress properly encoded files. I’d prefer my files Not work on safari mobile rather than have them look wrong everywhere.

Has anyone figured out a solution to this? Designing a website for a client at the moment, and was super excited when it worked yesterday evening. Arrived back in the office this morning and greeted with a black background…
It looked so good before
