Timeline compression and limit on audio tracks?
Hi –
Sorry for the weird title!
Here’s the problem. On a couple of recent projects, we’ve lost bits and pieces of audio tracks when compressing a timeline. There were never more than 6 audio tracks going at any one time and all the files were rendered where necessary.
However, when looking at the mv2 file, it’s clear that some times were lost, such as a sound effect or a snippet of music.
This does not happen in all cases where multiple tracks are stacked up, however, so it’s confusing as to why it happens sometimes and not others.
Is there something simple we’re missing? Is there a limit? We’ve now nested the tracks to work around the issue, but we’d like to know what’s really at play.
Thanks
Ron

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, sync-slippage, 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.
