How Do Mattes Work In Vegas?

[Steve Rhoden]

Simple, you just place it on an above track over the video
and change the Compositing Mode of that track to Multiply, etc.
Luma Keying and Chroma Key has nothing to do with the process.

are they files with alpha channels? right click the clip, properties/media, look for alpha channel. select whichever option looks best, premultiplied etc.

Alpha Channels and Mattes are two different processes.

reading the original question, I get the impression that the user has a bunch of video effects with a background that he wants to remove. so i’d expect that the files contain an alpha channel for that purpose. I may be wrong, only the topic starter can tell, by checking the files or rephrasing his question. ed
