When I overlay a bluescreen foreground video over a background video,
which is the best place for the despill filter? (a) before colorkey or
(b) after colorkey or (c) after overlay?
[foreground](a),colorkey,(b)[fg];[background][fg]overlay,(c)
I found here an example for (c) but I doubt that this makes sense:

Why do you doubt that it does make sense?
I doubt that (c) is the right place because at position (c) the despill
filter also affects the background video, which surely doesn't have any
contamination from the bluescreen.
Then use it after colorkey.
Thank you, you confirmed what I also thought is the best place for the
despill filter. But I wasn't sure.
Might be a good idea to add a short note to the documentation of the
despill filter.
