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.
