I'm trying to make a smoke explosion colored as a rainbow with any desired background. I have a white smoke explosion with green screen on the back already, but I can't figure out how to color only the smoke using premiere elements.
I tried with a transparent rainbow gradient image I made in Photoshop, but it colors the whole screen and not only the smoke, it looks like this:
Does anyone know how to do this?
I'm using Premiere Elements 11. I have little experience in it, but I can do basic things, such as video merge.
