thanks guys
the clips are cineform
seems the audio is unstable in AE
i intend to take each clip into Avidemux and extract a wav for each clip
when thats complete I will replace all teh clips in the composition with the wavs instead and then render out a full wav that represents the audio track
I can then redub it all
hopefully that will work
teh first wav out of avidemux scrubs and renders perfectly in AE so it should all be fine
(p.s. i totally get teh wav thing in AE and have always converted to wav to avoid problems but I did think that cineform audio would be ok seeing)
