Effective fbo with movie files?

hello all,

im looking for info on fbo and for me to load in movie files to them. my aim is to manipulate each frame with drawings, then export it. they would create a png/bmp files for each frame as well, so i can draw in the png/bmp.
is there any tutorials as such for fbo, or any files i can look at which are for what i need?

thanks
