Audio Drops when Exporting to Quicktime.

[Thaxter Clavemarlton]

Questions like this are posted very frequently. And many (most?) of the problems are solved by a simple procedure.

There is a function in FCP that is often overlooked… and it can help with many audio and video “skipping”, “sticking” and “missing” problems.

You should “Mixdown” the Audio for playback before you dub out of FCP, or during the edit, if you have audio/video stuttering, drop-outs or freezes.

NOTE:
Mixdown has even been demonstrated to help with slipping, skipping problems (or “missing” audio clips) for files being EXPORTED as QT (or similar) files out of FCP.

First, SELECT ALL of your audio tracks (highlight them) on the timeline, then:

Sequence Menu > Render Only > Mixdown.

You should see a dialog box telling you its rendering.

It might seem to make little sense that “Mixing down” even simple audio tracks will “fix” complex video “freezes” or random audio dropouts to tape or export, but it CAN.

NOTE: It does not matter of you only have one audio track, if there are random freezes during output, you should try the Mixdown.

Have you created any nests of your audio? I’ve had this cause issues similar to what you have described, specifically when I chopped a nest and took out a chunk of it.

I was able to solve it one time by trashing all audio renders, and rerendering.

Another time I was unable to resolve it but was able to export my movie in two sections – the first ended just after the audio dropped out, the other began just before the audio dropped out. For some reason the second one had all the audio and I was able to splice the two together.

Other times I have been able to chop audio nests with no issues.

Go figure,

Yes I do have nest and that is mainly where I lose the audio.

I thought it had something to do with that as well, but didn’t know how to go about resolvinmg it.

I’ll try both suggestions and see what works best.

Thanks

Mix down the audio in both the nest and the final sequence. that should help.
