I am running tcp x 10.0.5 and trying to do a multi cam edit. First when I brought the clips in they would not sync. I did the auto sync using audio and it just placed the clips back to back. Finally I went into the inspector and named each angle. FC finally tried to sync them but only got close. I had to finish syncing them manually. When I then started editing the clips every time I would change angles it adds a light pop to the audio. I am using the audio from camera A for the audio source and have it set as such. The active audio angle confirms this. I don't know if this issue will be corrected upon render or not. I gave up on the render idea because about 8 minutes in the audio was dramatically losing sync. The footage was shot on two mini DV DVX 100 cameras. I don't know what's happening here.

Rendered footage to .mov and it still makes a funky noise at every cut. I guess it's back to Final Cut Studio. This program disappoints every time I use it.

I've done many multicam edits and never had these issues. What are your settings when you configure the sync? What is the audio quality of all clips?

Have you done any real training for FCP X such as Ripple Training or macProVideo?

Agree with BenB - it's really hard to help you out without more information. I have done multicam clips with 8 camera angles and over 40 different clips and it's always synced up great (using just the audio waveforms from DSLR cameras). In fact, the multicam is the most powerful tool I've ever used.

Do all of your clips have decent audio?

What was your audio recorded to? Mp3? What is the Khz? You could have a sync problem if it's at 44.1 and not 48.

I shot the footage with a DVX 100 so the audio was 48 and both cameras recorded good audio. I did take the audio and separate it from the main camera audio source and dropped it to the timeline and now the pops are gone and the sync issue seems resolved but I shouldn't have to do these kind of work arounds. I did have to do a manual sync. The auto sync using audio did not work at all tho. I have auto synced up footage before and it seemed fine but not this time. That is one of my favorite features of fcpx. I just hate running into disappointments. FC 6 has never let me down doing multi cam work.

Because in FCP 6 you had to manually sync to start with. I've never had sync issues with X. Not sure what's going on.

But still, what are your settings when creating the multiclip?

Well I recaptured the footage. This seemed to allow me to auto sync the clips but the audio still drifts badly by 8 min in and continues to get further off. I have checked my settings and everything seems to match perfectly. Both clips were shot with 48khz audio and at 29.97 frames per second. The project properties match the clip properties. I have retimed the audio track to get it close but it's not perfect. I just did this as a test to see how close I can get but won't edit the program using this awkward work around. As stated before, I never had these problems with the same cameras using FCP 6. Yes, I know I could only manually or use timecode to sync clips in FCP6 but that's not the real issue. The popping problem at every angle change seems to have gone away but not the drifting. I have tested the footage from each camera individually, outside the multi clip, and the drift is inherent with each clip. To me that explains some of the auto sync issues but why the drift? I did go to the finder and get info on the files. They show up there as having a total bit rate of only 30,307. That's odd. I checked my camera settings and they are still at 48khz 16 bit. Is FCP X capturing my footage at a dif data rate than it was recorded and if so how do I change it? I don't see the capture settings options I'm familiar with.

Ah, you said "captured". You mean from tape? Verify, outside of FCP X, what is the audio on the actual tape? Is it 48kHz? Can be be absolutely sure?

The camera settings verify this, on both cameras. And I haven't touched them since the shoot and never do change them.

Report to Apple via the feedback page. This is just odd. I think I'm starting to see a pattern of 10.0.5 bugs slowly cropping up.

I was just handed some clips, original H.264 Canon DSLR clips, play fine in QT Player. Totally out of sync from frame 1 in FCP X. Very odd.

Thanks Ben. I will. Guess this project goes back to FCP 6 for now. Darn. Better luck next time. Yes, I don't remember this ever being an issue in .3
