OMF to ProTools and Back Again
Has anyone experienced a problem with audio drifting when an omf is sent to pro tools for sweetening and then final audio is imported back into FCP?
OMF exported from DVCPRO HD 720p sequence (16 bit 48k) – 5.1 audio created in Pro Tools – Import 6 tracks into FCP that were created in Pro Tools.

What kind of files are you importing? AIffs? BWavs?
Try this. Delete your aduio files out of the project completely, your bin, timeline, everything. Set your FCP easy setup to 720p24 DVCPRO HD.
Quit FCP.
Reopen FCP and reimport your audio.
Still out of sync?

Sorry. I forgot to include the sequence is 59.94

Okay. Do the same steps as before and choose the DVCPro HD 59.94 easy setup.

Andy I do this at least 3 or 4 times a month.
I’ve never had synch issues even with feature length 24 frame projects. (knock on wood)
one thing I do is embed a timecode window in a DV .mov file I give to
my audio engineer for picture reference.that way you can confirm from head to tail in pro tools that the pro tools
timecode and the timecode in the video are spot on to the frame, ensuring no synch issues.this often occurs if the frame rate or drop/non-drop are overlooked.

Thanks. The audio engineer suggested the timecode window. Is that created just using a filter in FCP or is there a way to do it with out rendering? Also, my sequence is 59.94, but the audio engineers say that pro tools is working in 29.97 (and there is no way to make it 59.94) Would that be an issure with audio?

[Andy Lancaster] “Would that be an issure with audio? “
What type of file are you importing, please?

create a new 29.97 DV-NTSC sequence
nest your 59.94 sequence within it.
add the timecode reader or other timecode filter
make sure you pick the one so that your sequence timecode
matches the timecode now showing on the video. (it won’t play in realtime, just scrub it to check)export an NTSC DV quicktime (self contained).
have your pro-tools enginer bring that in to pro-tools with a 29.97 session.
I have not done this personally, though I have done 720P 24.
But this is said to work.

Sorry for the slow response. I am importing wav files that were created in pro tools.
thanks.

Okay, did you try the trick I gave you?

Just wanted to add this for peopling who are googling and getting to this thread – the trick listed does indeed work. I was having the same troubles with a DVCPRO HD 25P timeline but this fixed it.
Thanks Jeremy!
