MS Pro 6.0 Overlay question. Which channel to use?

[Hulk]

I'm putting in some simple captions in a video. The captions were created in CG Infinity and are white text on a black background.

I'm currently using the alpha channel overlay option in MS Pro and am seeing a while line on two or three sides of the text boxes. Is there a way to not have this white line against the black border?

Try using the Luma key instead. This will allow you to use the Blend/Opacity setting, which is useful for blending problem edges.

Blend/Opacity is very useful in Chromakey and Color Key effects as well.

Thanks for the tip. I'll give it a try.
