Hi,

I'm trying to put together a video bluescreen and I'm just not finding the right object I think. pix_multiply sort of does what I want by dropping out white in a video and replacing it with another video but how do I get this working with a defined colour (i.e. 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
