hi Ted.
its strange alright, i don’t really know if there’s a simple answer.
-can you get the DV capture from the post house that did it?
other approaches:
1.
re-sync the audio in a FCP timeline, and export
2 ways to do this: every 150 seconds, adda frame, or rather duplicate a frame of audio,
(blade the audio and slip the right hand side 1 fr)
(NB the 150 seconds is according my calculations, which could easily be wrong, I’m a bit tired, maybe you should double check them!)
find you end sync point, and trim the audio to there
double click into the viewer,
mark in/outs around your picture in the timeline
and do a fit to fil edit back into the timeline (drag to GREEN window in canvas, or Shift+F11)
this will stretch it out to fit the image.
exporting from FCP will NOT add generational loss to your video,
if you export a QuickTIme move, using the default “Same Settings”
2.
extract or export the audio from the QT file
maybe bringing that int FCP it will behave???
one more thing to look into:
do your sequence presets match your clip?
there is a known fault in FCP where imported AUDIO ONLY will take on the frame rate of the selected sequence preset,
and if that does match your video frame-rate, then the audio will drift against the video when synced.
its hard to believe that this could cause a file containing both the video and audio to drift within itself,
but who knows??
good luck with it,
nick
