Transparent capture

[JosiahFu]

It would be nice if the capture feature had an option for transparent background, replacing the white background and grid.

How technologically or computationally challenging this would be?

I believe gif and mp4 do not support transparency, so those options would have to be disabled for transparent recording.

Love this idea! Hopefully not too hard: have to find the function that draws the white background, and tell it to not.

It's already possible to disable grid in the normal wrench menu, so that should not be inside the capture.

Thanks for the shout-out about some export types not supporting transparency. GIF is probably a lost cause, but we might be able to use H.265 export for the mp4 container (currently use H.264). ZIP, APNG, and WEBM should all work with transparency.

The captured frames are stored as PNGs, which supports alpha, so that's not a problem.

gif technically supports transparency, but it's fully transparent or nothing
