For example, say my video has a green screen in it; Is there a way to eliminate the green inside C3 when playing back the video but leaving the other colours intact?

I can use the ReplaceColor effect on the video for example, but it doesn't allow the replaced colour to have any alpha so I can only replace my green with a solid colour.

Thanks

Simon

Bump. I just read the new GIF tutorial and could transparency be the main benefit to using animated Gifs?

I think you'd need a custom shader effect for this - basically like replace color but replacing with transparency instead.

Oh okay. I never knew custom shaders were something I'd be able to create myself in C3. Is there a guide on this anywhere?

It's covered in the Addon SDK documentation.
