Hi Richard I've tried the Track Matte Key trick and it worked (just had to choose "matte luma" instead of "matte alpha" in composite). It's not perfect, but for the thing I'm doing right now it's good enough. It cuts a bit of the edges (which in this instance only shows when I reverse the mask).
I have to try the trick with the .tga files later. Maybe it works better when working with smoke and explosions. The reason I don't work in PI, is because what I'm trying to do is create a background containing some trees. Since I can't find a way to move background images in PI I have to make an image, where the tree trunk (which is a still image) is in exactly the right place. Therefore I find it easier to work in Premiere, where I can move all the images around. Thanks for all the help everybody!!! dixib --- In [email protected], "Richard Peoples" <[EMAIL PROTECTED]> wrote: > > Working with 32bit tga sequence that is rendered from PI is really not a > problem at all.
