Here's a humdigger for ya

Hello -

I've been killing myself over this issue all day - please please help!!!

Here's my issue:

I'm working with footage filmed with the HPX500 at 24p (or technically 23.98), compression is DVCPRO HD 720p60. All footage was transfered with P2 cards. On the shoot we had an audio guy who recorded sound at 96Khz with a 24-bit floating integer. The HPX500 did NOT record audio - our audio guy set up mics and recorded through pro tools. I brought all my footage into FCP. When I brought in the clips I accepted the sequences settings to match my media (from the P2 cards). I converted all the audio to 48Khz at 24bit.

Here's the problem:

I lay in my audio (just sound effects from the shoot - smash noises) Line everything up perfectly. When I play back the audio is completely off - getting worse towards the end. I've tried everything. The closest I've came to finding an answer was off this forum: http://support.apple.com/kb/TS1712

But it still didn't fix my problem. Any advice??????

Thanks,
Amber
