Hello! I’m trying to export some projects with a transparent background so I can add some visuals in another program. Its a mess to use a green background for the chromakey so I’d just prefer to export a transparent video, but from what I’ve seen here it’s even a more complicated mess to deal with (Discolorizing in .mov, completely black on other alpha presets, the other options don’t work, and the only people who succeeded using text and images instead of videos, which i’m trying to use) So I’d like to know how do you do it guys.
Because I don’t use apple machines, my experience with .mov is limited, but does the mov format even support alpha in the baseline? As in, you don’t need an extended version of it, standard .mov works?
.mov is just a container format, like MP4 or WAV/RIFF.
What you can or can’t do, at least in this respect, entirely depends on the codec it’s being used to contain (and which implementation of that codec you are using to encode and decode it). You need to be using a codec that supports an alpha channel because it doesn’t really fit in to the traditional luma/chroma separation used to encode video or the reality of recording it. And you need to be using it on a platform that supports that. Because Politics and Greed. Hence chroma-key as the more historically Usual way to handle this.
And that’s all before you get into bugs with alpha blending and colourspace handling when trying to actually composite it with something else.
