Audio problems while editing in multicam…

[David Eaks]

I had this problem once. It was wierd, it’s like I could “hear the cut” even though there is no change in the audio through the video-only angle change. I just created a new multicam clip, it was fine, deleted the old one and was on my way.

So, apparently it was a glitch with the multicam clip itself, not the original media. Fortunately I had only done a couple cuts before starting over.

I’m having the exact same problem. There is a practically inaudible pop when the cameras switch angles, although I am not switching audio tracks.

How far into the edit are you? I’d recommend that you export a small test clip and see if the problem shows up in the exported file.

The one time I had this problem, the only thing I found to fix the issue was to create a new multicam clip. Even with the same media as before, the new one was fine. Never found any explanation or fix.

I am having the same problem too on all of my multicam clips. I get the popping on about half of the cuts between angles. I can fix the problem (usually) by moving the cut forward or back a bunch of frames. When I export the file, i still hear the popping noises.

I happen to add a little compression to the audio in the multicam editor before placing on the timeline. I thought maybe that had something to do with the pops but it just makes them louder. They are there whether I edit the audio or not it seems.

I have been seeing this issue for several months now since I started editing multicams (since Fall of ‘2012). I am now at the latest version 10.0.8.

Same exact issue. I was cutting three cameras, cutting video only, audio locked to one track (separate from the cameras even), and I can hear many of the cuts.

here’s what the timeline looks like, and you can see the cut: https://www.screencast.com/t/ux7bwM9Zmx

And it turns out that the audio is actually cut here; see how I can select that entire clip, as if it was a totally unique clip: https://www.screencast.com/t/pwJVoPYVE

The workaround was relatively simple, but only because my edit was mostly straight-through. I had very few actual cuts out of the take. But I was able to extend the audio across all the angle edits (until the next real cut came along), which pushed the original audio down one track, then select all those and reduce the volume to zero: https://www.screencast.com/t/t0plP6M146

Tedious, but it worked. Can’t imagine why this is happening in the first place though.

Same problem here. I’ve applied a temporary fix until I can troubleshoot it. My edit is from a 3-camera shoot and I only needed one audio track/source, so after the edit, I imported the audio from the correct camera and it sounds just fine. I lowered the “bad audio” to the floor and only used the uncut audio track.

Not only was there a pop during the cuts in the multicam audio, it also cut off a syllable each time. It is very noticeable when a cut happened mid-word. I will troubleshoot and post a solution if I can find one.

Jason, are you fully up to date? I don’t do much multicam editing but just finished a project and had none of these issues; maybe it was fixed in a recent update? In fact I’d forgotten completely about it and had to re-read my own comment to see WTF the problem was!

Hi guys,

I’m not sure wether it is too late or not to contribute to this, but I stumbled on this thread while looking for the solution to that exact same problem.

I couldn’t find anything to solve it (other than re-dropping the multi cam clip on the timeline and re-cutting). Until I noticed that my waveform on the newly dropped file was different than the one which had the “clic bug”. I went on to check the Angle editor to see if there was any effects on my initial multi cam audio (especially the audio track of it … none).

And then it came to my mind that Final Cut allows to also drop effects etc on the cutter multicam straight on the timeline. (Which is useful when you want to apply selective effects to different cuts of a same multicam clip).
There is was: Noise-reduction.

The clic/lostframe however it has been called was related to it. Desactived, no more clicking to be heard.

I went a bit further though and tried to activate the noise-reduction on the audio track from within the angle-editor. Same issue.
I guess it is because the noise reduction does not really makes it measurement on the whole audio track. And no matter where you activate it, it does always makes its measurements on the timeline cut and not on the overall clip. Bug in FCP … not sure, might be. But there might be some underlying reasons that I ignore for it…

I’m quite sure most of you that had the issue had it without effects and this angle-editor/timeline view issue I had. But thought it might be worth sharing in case it happen to someone else. Noise-reduction = no go with multi cam.

Solution is in the end to apply noise-reduction separately, export the audio, re-import and done … not really convenient I agree.

OK Here is the best solution I discovered for me for this multi cam audio popping. First edit in your multi cam clip to the time line. Then lower its audio track to 0db. Then edit just the audio of the best camera angle audio on an additional audio track below the multi cam audio track at the same in point of your multi track. Since it is on its own track it will not be affected by the multi cam cuts. This also allows you to put audio effects on it as well.

I hope this works for you.

I had the same problem, then noticed someone here wrote ‘turn off the noise reduction’ that I had applied to the track from one of the cameras (using only 1 source audio as normal), and that seems to have fixed it instantly, so I didn’t have to restart the edit (2 hour edit) with over 400 cuts in it….phew.

So from my experience, if you have applied some audio effects, maybe them thats causing it, as I noticed I didn’t have the issue before i started tweaking the audio either.

Hope that helps (using FCPX).
