Music changes after duplicating sequences
Hey all,
I’ve noticed this problem every now and then. I’ll be working away on a cut, send off to the client, get changes back, then duplicate the last sequence I was working on and go from there. What’s odd is that somehow the music gets all screwy in the new sequence even though nothing has changed.Screwy might be a bad term, but basically the music will be playing, and looks fine in the waveform, but it suddenly plays a totally different part of the song then what it should. When that happens, I have to go back to the original music file in FCP and re-cut it in that spot. So it’s only the track in the sequence that gets messed up, not the original file. It’s so completely bizarre. I have no idea why that happens or what causes it, and it doesn’t happen all the time. But the problem is, I always have to check the music is ok with each new sequence and that’s time consuming. Duplicating shouldn’t screw anything up.
Anyone have any thoughts or experienced this themselves? Thanks!

Use the render manager and trash your audio render files for that sequence.
It’s in the tools menu.

Is it mp3 music? FCP does not like mp3s even though it says it does. I always convert to AIFF.
What happen when you take the audio in the new sequence offline then relink it?
Thank you

But it happens in lots of different sequences, and it doesn’t happen all the time. Next time I start a project, should I just delete the audio renders after the first sequence is made to avoid the problem down the road?

They’re not MP3s, they’re AIFFs.
I haven’t taken them offline and relinked them so I don’t know what happens. What’s strange is the original file in the project never goes bad, it’s only what’s in the sequences that gets messed up.

Unfortunately, it’s how FCP works.
Render files are named after sequences, and so if those names cross paths, sometimes FCP plays back the wrong render files.
Trashing those temporary render files clears that problem.
You can always trash them from the Finder as well in your FCP Docs folder > Audio Render Files.

What you described has happened to me with Mp3s that’s why I say it.
I would take the music offline in the new sequence and then relink and see if it fixes it. Then at a least you have an easy work around.
Make the music clips independent in the new sequence if you dont want to take all the music clips offline in the other sequences.
Why is everyone referring to rendered media? Why are the audio clips need to be rendered if they are AIFFs, maybe I’m missing something?
Thank you

If you have filters on your clips, it requires a render. Sometimes if you have enough clips stacked in top of each other, there’s a render. Even if the files are aiffs, sometimes the sample rate is 44.1 instead of 48k and that will require a render. Nested sequences sometimes require an audio render.

Boost you realtime tracks up to 99 in your preferences. What are you using a g4? I rarely have to render audio track with filters and i have had 20++ layers of audio w/ filters.
Did the offline re-link thing work.
Thank you

Are you talking to me?
No. I am not using a g4.
If I have a stack of 8 tracks of audio, a compressor/limiter on each track, and then you start stacking other filters on top of them, and then add a dissolves between clips, and then nest that in to 2 channels, there are times when I need to render. No big deal, it takes a few seconds. Audio is easy to process.
There are days when I am trying out music and it comes in 44.1, i simply add it to the timeline and render. When it gets locked in I convert to 48k.
I don’t know what the big deal is here.

I was. It just seems like there is a lot of rendering for nuthn. I reproduced what you described withw the 8 tracks and a song at 44.1 and added a compressor, 3band equalizer echo and sample delay (just picked two more randomly) and I still at real time (no render needed).
Not for nuthn cause this is really unrelated to your problem, but did you boost up your real-time audio track in the preferences? I saw your machine specs in your profile. It’s fast enough.
What I am saying is, maybe you won’t have this problem if you dont have to render audio in the first place.
Thank you
Roy
