Ok, interesting, did i mention that this is live? I have been rendering with premultiplied alpha channel. I’m using a Roland V-40HD and it’s DSK facility. But what your saying makes sense, i just need to overlay a stream on top of the other. Sounds like the keying is throwing off the color.
Thanks very much for the (probably very obvious) advice. i’m new to this. I have some experimenting to do before i report back
Thanks a million
