I am struggling to find a cause for the lack of transparency while rendering movie clips.
I have some green screen footage. In the compositor I have added the movie clip and a keyring node. Selected the eye dropper and in the viewer node it is showing as expected, however when I render the image the green screen is gone but I’m left with a black screen where it used to be with no transparency.
Masking still images and composing them isn’t a problem and I get the desired result but I can’t figure out why when I’m trying to do it with a movie clip it’s different.
All the colour settings are rgb, the transparency is turned on, I’ve got the file path saving to my desktop in an FFmpeg format. It plays back fine, the render quality is good but for the life of me I can’t figure why it won’t show transparent. Can anyone point me in the right direction?
