Final Cut Pro – MultiClip – Audio not syncing
-
There’s an issue in FCP 7 that didn’t exist (I think) in FCP 6. If there’s a gap between clips, the audio & video will become un-synced. If you fill the gaps (and that means at the program start, too) the sync is good. Try adding slugs and see if it helps.

use OUT points not IN points

Just like an earlier member posted, you need to do the following to multiclip using cameras and external audio:
1. Stack cameras and external audio files in timeline according to timecode.
2. Sync all three sources in the timeline.
3. put the playhead at the OUT point where all three sources align.
4. Match back and set OUT point on each of the cameras
5. HERE IS THE IMPORTANT PART: Match back and place OUT point on external audio AND remove the IN point (OPTION “O”).
6. Select all three clips and Create multiclip using OUT point as method.
This will work. We’ve done it for two network shows, but you HAVE to REMOVE the IN POINT on the External audio clip or it will not be in sync in the multiclip.

CORRECTION TO MY PREVIOUS POST:
TO REMOVE THE IN POINT WHEN YOU MATCH BACK TO THE EXTERNAL AUDIO SOURCE CLIP, USE OPTION+I.
IF YOU DON’T REMOVE THE IN POINT FROM THE EXTERNAL AUDIO CLIP THE MULTICLIP WILL BE OUT OF SYNC.

Make a subclip of your audio and everything should sync fine. The problem seems to come in when your audio clip has a much longer lead in than the video. Not sure why but fixed the issue for me.

I am having the same exact issue right now creating multiclips where the audio jumps 5-10 seconds out of sync with a documentary I am working on. It’s a two cam shoot using a Canon 5Dm2 and a Canon 7D shooting at 23.98, and recording the audio separately with a Tascam DR-100. I’ve worked with this setup before and have been able to sync both video sources and the separate audio source by using out points (as mentioned above) at our common marker and then creating a multiclip.
However, now I am running into the same issue described in this thread for the first time and am not sure what is different between this project and previous projects where I have done the same exact thing. PluralEyes is able to sync all three clips perfectly, but when I try using PE to create the multiclip, still the same thing. This isn’t a frame rate issue, but some type of bug in FCP.
I did try the “audio subclip fix” but to no avail. Does anyone have an idea what may be causing this?

I have had several issues with FCP 7. The issue of audio/video out of sync that I have had is not with aligning the clips (as someone suggested using plural eyes), it was in FCPs alignment after “I” had PERFECTLY set the “In” points. I even tried aligning using “out” points.
The problem (for me) exists in the encoded footage. FCP was obviosly having issues with it. It could aligned the other 2 cams perfectly (or vise versa). Whatever the case, 2 of the 3 cams would align but 1 would not (in multicam). I can only assume the footage from the 1 cam is/was corrupted somehow. Whether it’s a bug or not, needed to be remedied.
Note: Something I have noticed is that FCP 7 makes it’s multiclip in alphabetical order according to the clips names. IRONICALLY the clip that I had problems with started with a “B”, which meant, it was going to be the name of the multiclip. Not sure how all that works but, when I lay the multiclip in timeline, it starts off with the audio and video from the messed up clip. Yes, I can go in to the multicam menu and change which audio and video I want displayed but, that didn’t seem to make a difference.
***SOLUTION***
Lay the footage that will not sync in a NEW Timeline.
Export footage with same compression (I renamed it with a name that wouldn’t be used by multiclip to aligned first example “TEST B2”.
Import clip from wherever you exported to.
Realign clips using NEW exported clip.
This fixed my problem. Hope it prevents someone from pulling all their hair out like me! Smiles, Mic -
Great to see this thread as I was also having the same issue. I worked with and did a multiclip fine with a music video I cut recently, but when I tried to apply the same steps to syncing two camera angles and a separately recorded clean audio track, no dice.
I did as everyone has said and synced it how I would sync anything. Laid in the clean audio, making a mark at the slate board clap. Then found the same slate sound on the poor, attached audio from each video clip, and put them on top of the audio in the timeline. Once everything was synced, I deleted the poor audio leaving just the clean audio and the two video clips.
But when I select all three and drag and drop in a new bin to make a multi clip, the multi clip is completely out of sync and I couldn’t understand why. Also, one clip ran for the whole length of the clean audio, but the second angle for some reason was chopped up. It ran for about 2 minutes at the beginning of the clip, then cut off, then there was a separate video clip that started from the middle of the audio. But I shouldn’t think that would cause any issues.
I didn’t try using out points, so I will try that. I’m really hoping that works and it’s not a bug. I didn’t shoot or transcode anything I’m working with, so I have no idea what anything is or how it was shot.
If anyone has any other suggestions or words of advice, would be great to hear it. Thanks!

I just encountered this problem myself and the easiest solution I could think of, quicker than out points, was to mark in and outs of the audio file and make a subclip. Then you can multiclip that subclip and the video via in-points and it all lines up.

Hi
After spending hours on it myself I would like to propose a quite simple workaround using PluralEyes.
Place video 1 + sound 1 on tracks 1
Place video 2 + sound 2 on tracks 2
Place external audio 1 on track 3
Place external audio 2 on track 4Use PluralEyes with the option replace audio. You obtain a sequence with 2 clips: the video + the external audio (you probably didn’t want to keep the audio from camera did you?)
On this timeline set an IN point for these same clips at the same timecode. Then do MAKE MULTICLIP, using TIMECODE.
It works for me.
Just spent a whole day on it 🙁
