Hi,


I have two videos:
1 - An animated "title" text video (letters moving around with a complex schema) with a black background.
2 - Another video taken with a camera


Using libpigment, I tried to put the video 1 over video 2 but the black background of titles is not transparent and covers the second video. If I try to change alpha value on the whole video the black will be mixed with the second video making it darker.


Is it possible to make transparent a only part of the video with a specific color (the black on the first video in my case)?
