Using either gimp 2.8 or an Adobe product, I want to create fiery letters that play in powerpoint 2007 on a bigscreen TV. Gimp will not accept any movie files, so I simply inserted it into the powerpoint slide itself, then created a black, stenciled message in gimp, and brought this to the front on the slide. Unfortunately, the playback was highly pixilated, and the stenciled text layer simply disappeared just as the movie began to play. I know this is probably no big challenge for some of you folks. Please help.
