Audio playing at wrong speed
I’m editing a trailer for a feature.
The feature is 25fps ProRes 1080i.
Client provided audio split tracks as .wav files, which, according to Quicktime, are ’24-bit Integer (Little Endian), Mono, 48k’
and which have an embedded timecode track.Problem is, when I bring these into FCP, they play as if they’re DF — i.e., at 99.9% of the speed of the feature!
In order to make them sync to the feature, I have to apply a 99.9% speed adjustment.
They also load in with 29.97 timecode.Is there any way to import them so that I don’t have to adjust them?
I tried exporting from Quicktime with all kinds of settings — nothing worked — but I don’t really see how to give an audio file a framerate!
Even if I ‘extract’ the audio track, or ‘delete’ the timecode track, it still loads into FCP as 29.97Thanks for any help….

SOLVED —
After more searching, I found the solution.
I changed the easy setup to 25fps — then re-imported the audio.
Now it reads as 25fps and does not drift.Whew!

When starting up FCP initially, or after trashing prefs….did you set the ‘easy setup’ for your 1080/25i format, or just leave it at default and skip to your project? I’ve found that that can have an effect on audio drift/sync if, say, the initial easy setup of ‘DV-NSTC/all frame rates’ is kept, even though your project is a different format. Don’t know if this is your issue, but here’s some more info on what I alluded to. Look near the bottom of the thread….

That solved it for me regarding exporting and importing audio files while working on a 1080p ProRes (HQ) in both 24 and 23.98 fps.

For the record, ever since FCP tried to be clever and read embedded timecode info in bwav files the forum has been inundated with people reporting exactly this sort of drift problem. Unless there is a really important reason to deal with bwav, I recommend everyone request their mix files as 48khz aif.
Often the problem is operator error in bringing in a wav file into the wrong frame or timecode rate project. I am a bit baffled at how this mistake is so often made but once FCP thinks a file works at a particular timeocde rate, the way to fix the problem is to delete the original and reimport as an aif or if it must be wav, into the correct project.

hey there,
i’m having a similar issue, only i edited the sound at 24 fps, but when i load it in to final cut it changes the timecode to 30 fps….
i tried deleting, then re-importing the audio, but it hasn’t fixed the issue…
did you have to re-name the audio before you imported it? is there a detail i’m missing here?
thanks

I have had the issue with both WAV and AIFF files.
And yes, I did end up having to rename the original files. I did NOT need to trash my prefs.
1. Delete ALL the “bad” imported audio clips from all your bins.
2. Change your easy setup to anything that has the right frame rate.
3. In Finder, RENAME all the files. It’s enough to just add a “B” or a “2” or whatever at the end. (I use a great free app called Name Changer, link below).
4. Now re-import them. Might be wise to test one first.Good luck!
