Hi Kostantin,
Make sure the sound from the cameras and any other sound files share the same frequency (usually 48k) and that your sequence settings are set for that same frequency and fps as the footage. If that’s not the case, FCP might import the sound files with different frequency and fps and that could give you problems with the synchronization. Let me know if you have trouble.

Thank you everyone for your replies. You helped me understand the way the video was shot, I’ll give it a try sometime soon!

Thank you Vishesh and Joseph for your help and your tips. Do you mean that all those tricks were done on camera, during the concert and none of it is overlayed/composited footage? That’s really amazing. Thanks a lot again, I’ll try to look into it.

I just tried to do exactly what you said (I’m in a similar situation, trying to match the concert’s 44.1khz sound file to the 48khz footage), but it did not work: after resampling and importing the resampled 48 khz sound file I still get the “green line” in the timeline telling me that the sample rate does not match. Do you guys have any advice?

UPDATE: doing some more research I found that the problem might not be related to the multicam edit, but due to the fact that I’m trying to sync the 48 khz audio from the camera with the 441. khz of the audio files I was given by the sound engineer.
Unfortunately, after converting the audio files from 44.1khz to 48, nothing has really changed, as you can see in this picture of my timeline:

It is clear that the mismatch in the audio file is quite significant (I believe it gets to more than 10 secs towards the end of the song). What seems quite strange to me is that the audio doesn’t seem to slowly drift away, but rather seems to just differ significantly in the interval I highlighted in the picture.

Cool, once again thanks for the input guys. I have moved away from the idea of the multiclip because I can’t do it with all the footage that I have anyway. I’ll probably have to synch every clip with the audio but it’s gonna be a 5-min thing so it won’t be too long hopefully. Thanks a lot again.

After some testing, I figured that if I use Compressor to convert the 25fps footage to 23.976fps the result is acceptable, but it takes a very long time.
Toi avoid converting all my 25fps footage, but only the clips I need, would it make sense to edit my sequence with the original footage (with the two different frame rate) and only when I know what clips I’m gonna use in the final edit, convert solely them fro 25 to 23.976 fps?
Then I import the converted clips in FCP, use them to replace the original 25fps clips and export everything at 23.976fps. Does it makes sense or will I encounter problems I’m not foreseeing at the moment? -
Perfect. Thanks for clearing it up.

Thank you guys, I must have misunderstood Rafael’s post because I was going to use Compressor but I thought that with workflow I would jeopardize my chance of synchronizing the audio. So conforming with Cinema Tools is going to present me with an audio synchronization problem, but not Compressor right?
