I'm trying to export a 720p HD video file that I captured from my PS3 via the H.264, no re-encoding option. Since this is no encoding, the export is very very fast. However, when I try to view the finished file via QT or VLC, the video is very choppy and the audio is screeching and all choppy as well. Can anyone tell me why this is happening? A friend of mine with the same setup is having no issues exporting his video clips with this method. We're clueless!
