In all my Video works in iMovie HD6 or iMovie'08 to 11 or FinalCut Express 4 or FinalCut Express Pro 6
I ONLY use
• .aiff - 16-bit 48kHz or 16-bit 44.1 kHz (from Audio-CDs)
or if audio is in iTunes I then I collect needed sounds into a new PlayList - Then I burn this as a Standard Audio-CD (NO .mp3)
So - for me - no .mp3, .vma or other strange formats - all converted to .aiff
So I convert all 32 kHz audio to 48 kHz (else my audio goes out of sync.
By keeping this I get near to Zero problem with my Audio in all my projecs.
