audio levels in timeline vs in export -- something is funky.
on Aug 19, 2012 at 5:21:04 am

Hi -- my edited sequence is perfect. I have vo, music, and everything is right. Somehow though, when I export the sequence, the levels jump for a few seconds such that it just gets louder all of a sudden, as if the levels had been key framed up .. but indeed they have not been ... and they sound fine inside Final Cut. I can't figure out why this would be ...

I tried:

- restarting
- trashing prefs
- copy/paste sequence contents into new sequence
- creating a new empty project and dropping the sequence in
- trash render files and re render
- log in with different Mac user (for some reason this sometimes fixes my render bugs)

All this to no avail. So how can it be that something that sounds right in the sequence can sound wrong on the export??

Many thanks.

What is the format of the source's audio and video files, and what are your sequence's settings?

The video is Prores LT 1920 1080 25fps ... vo and music is .wav from a zoom h4n....

Sequence settings match video settings.

Is the wave audio 48khz sample rate and is the bit depth 16 or 24 bit? FCP really struggles if audio doesn't match those settings. Also the sequence should be set to 48khz.

Yes the audio and sequence settings are both 48k 16bit.
I did just find a workaround.
I realized that if I exported only a very short section that includes the affected audio, it exports ok! So ... I exported three seconds, it came out fine. Then I reimported that new quicktime, replaced that three second chunk with the new quicktime, reexported the entire sequence and now it is fine.

Weird!

So problem solved for now, but still of course would love to understand why that happens, to make sure it doesn't happen in the future.

Hm.
Thanks :)

With your completed sequence, you need to render not just Audio tracks but choose "Mixdown" as a very last step. If you don't there might be artifacts of the audio editing and level work remaining from past actions that were not properly discarded.
