Hi
I've triedpix_background and can't see how two images are fed in (but
it's late and I need to come back to it again later in the week). I
had already tried pix_chroma_key without much success but I'll have a
look at this tutorial and see if it helps. Again if anyone has a
simple example that would be great but I'll keep chipping away at it
in the meantime.

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:http://www.blendedplanet.com/?Freebie_Tutorials:The_Ultimate_Keyer
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
