hello...
i would be interested in this too if anyone has something. i actually was just trying some stuff out with a green screen but did not get very far.
although i did not play around for long i did have trouble getting the [pix_chroma_key] to work well (or do anything at all for that matter).
i just did something like:
[gemhead 1] | [pix_video] | [pix_alpha]
and
[gemhead] | [pix_film]
...but im sure there is someone that knows something better optimized for green/blue screen work.

not necessarily
white but the blue or green normally used in studios).
There seem a
few objects that deal with different ways of mixing images/videos pix_mask, pix_mix, pix_composite etc.
Which is the
right one to use? Thanks in advance.
[pix_chroma_key] could do what you need. For higher quality results you'll have to use several objects and use some compositing techniques like explained here:

It's for blender3d and probably overkill for your needs but you can use some of its basic principles in GEM too.
- btw has anyone done something like that in pd? I only
used it in blender some time ago.
cheers, Martin
