Music changes after duplicating sequences

[Jeremy Garchow]

Roy, I don’t have a problem.

Danielle does and we are veering off track.

That green line on the 44.1 audio renders when I render all, as do all filters whether they technically need to or not. Sometimes, those renders get jumbled in FCP7 due to the way FCP7 names it’s render files after the name of sequences. It’s the way it has always been.

Danielle has a problem that the wrong render files are being played back. It’s a really easy fix. Delete the render files.

Hi Jeremy,
I think you’ve answered the question. It must be playing back the wrong render files, because the song plays, but it’s not the right part of the song which means it must be playing back something else.

That’s very odd though still, because each sequence is named something different, but who knows!

As this project just finished, for the future, every time I duplicate a sequence to make changes to it, should I just delete the render files every time?

Thanks again! So glad I understand what the problem is and hopefully how to fix it. (I say hopefully only because I haven’t had a chance to try it out.)

Yes, but sometimes those attached render files are still attached to old names, and FCP7 loses track.

It’s up to you. Before I export a master, I usually trash all render files and rerender, but it’s an old habit from back in the days when FCP’s renders were even worse than now.

Audio renders are really easy to rerender so there’s no real penalty, especially if it ensures that your program will be correct!

Definitely always worth it to make sure it’s correct. This project it was a pain in the a** because the sequence was 5 and a 1/2 minutes long. So I’d watch it, but just to make sure the audio was good, I’d watch again just playing the music. So it took over 11 minutes just to check before exporting. I shouldn’t have to do that.

I will definitely try what you’re saying for next time. Audio takes seconds to render so it’s no big deal to re-render it. I also just noticed as well that the audio is AIFF, but 44.1. I’m sure that didn’t help. Next time I’ll make sure it’s always 48.

Thanks again for your help!

A really easy way to change this is to right click on the audio clip in the timeline and choose “open in editor”.

This should open up Soundtrack Pro if you have it installed.

Find the “Process” menu and change the sample rate to 48000. Click OK, then hit save (command-s). Very important to hit save.

Command-tab back to FCP, and you will see that the green line is now gone and that clip won’t need to render anymore.

Ha! This one again!

I had this years ago – Sudden Explosive Sound Syndrome (SESS). It’s one of life’s great mysteries.

It’s a special FCP effect where one of your tracks is suddenly playing back something completely unrelated – like a Brass Band VERY LOUD. It was included by Apple at vast expense and I haven’t heard this problem since FCP 4.5.

Do the usual – trash prefs and audio render files – oh, and be sure that you aren’t using mp3 files. You ABSOLUTELY must convert these to something sensible like .aif or .wav.

You are not alone.

Harry.
