Kinda strange issue here.
I've been cutting together a multi-camera edit of a concert in FCP 6 and by the looks of the preview everything looks perfectly in-sync with everything else.
i'm rendering it out as an mp4 because i'd like to keep my footage at an HD resolution (in this case 1280X720) and keep it a small file size to put on my vimeo account.
for some reason though, once i rendered it out the final product goes in and out of sync with the audio.
when the footage cross fades to another camera angle the audio jumps by about a second, and when it cuts to a new camera angle the audio syncs back in.
again, the preview matches perfectly with the audio. is mp4 the problem? any other recommendations for compression? this is going on my vimeo account so i don't think divix will work.
here are the settings i used (not sure if it matters)
MP4 > h.264 > 3000 kbits/sec > 1280X720 > frame rate: 30 > key frame automatic
multi-pass was selected in video options
in audio i selected 192KBS and the encoding quality was set to best
