compositing
I have Vegas Movie Studio and want to add smoke to a clip. I have the clip of the smoke with a black background and gray smoke rising. Now I want to overlay it onto my base clip. How do I do that? Do I need screen mode with the full Vegas 6 to do this?
I can adjust the opacity of the smoke clip and run it on top of the base clip, but it darkens the clip and does not look realistic.

First, try adding a sony “Mask” effect to the smoke.
You may also need to change the smoke track to “Multiply (Mask)” and possibly make the underlying video a child of that track.

Ed:
I will try the sony mask. Thank you.
However, I have tried applying the multiply mask to the smoke effect and putting the base clip as the child. When I do this the base clip (underlying clip shows black until it gets to the point underneath the smoke clip and then both clips show for the duration of the mask only. In other words when I apply the mask and click on the base clip to play in the timeline, it is all black except during the mask portion. Am I doing something wrong? Will it render correctly? I would expect the base clip to play all the way through and the mask to blend in for its duration, not black out the entire base clip.??

Take a look at Vol 3 #1 of my newsletters about ways to split screen. Substitute your smoke for the black/white generated media.
