I do not have Quicktime Pro, but I am trying to encode a movie into the Quicktime Movie Format (.mov) with the H.264 codec, on 10.4.1. I have tried this from iMovie and directly from quicktime. It starts doing it but then hangs each time, and the file it creates never has any data. I then looked on the Apple/Quicktime website and I saw that QTP allowed you to encode in H.264. Is that implying that you cant do it with just the player, or iMovie. I assume it does, but then, why make the option avalaible and lead you on? Will I need Quick Time Pro? Thanks.
