You can either use masks in AE to cut the kids out or, if you save out of Gimp in a format that supports alpha, you can just import the already cut-out picture. Also, as I mentioned in a previous thread to you, if you have the heads cut out and saved in a format that supports alpha, you could drop the heads in with Premiere too.
You really need to start here: Getting started with After Effects After Effects is many leagues more complicated than something like Windows Movie Maker. You will land in even more frustrations if you skip a foundation.
Thanks. It worked.
Used gimp to create the pic the make the background transparent. Had to do some googling for that but didn't take long. The key was making the pic alpha and exporting it as a .png
Then I moved each pic into AE and it worked perfectly.
Ya I did some intro tutorials for AE a couple months ago but not Premiere. So I wanted to stick with AE for now since I remember a lot of those tutorials. And the video is done.
I'm glad you got it done!
