I'm doing a youtube cover and recorded the audio into cubase while capturing video with my iPone 5. I loaded the files into iMovie and messed around until I found the correct spot for sync. When I play it from the beginning it's in sync, but as it plays the audio moves very slowly out of sync. At the end of the movie (around 4 minutes) it's totally out of sync, and the audio is like 0,5-1 second behind the video. Is this because the audio is recorded at 48k and the video at 44,1k? If so is there anything I can do to correct the async with the files I got? I really hope I don't have to do it all over again...
