Audio Drifting. Tried everything.
I was given a project to edit; and for the life of me and I can’t figure out an audio drifting issue in FCP7. There’s two cameras (Go PRO & Canon T3i) that shot at 29.97. External audio is 44.1khz. The project is set to 48khz and 29.97fps. I used the “resample” tool in both audacity AND izotope to change the audio to 48khz. The issue still persists. This is a puzzle I cannot figure out. Any help appreciated.

a common audio drift problem in FCP is caused by your current sequence settings frame rate (in your A/V settings) not matching your working frame rate.
check your A/V settings.
make sure your selected sequence setting has a frame rate of 29.97nick

then re-import the audio

All framerates are matching. When changing the sample rate from 44.1 to 48…should the duration of the audio change?

So I found out something interesting I’ve never seen before. I inspected the original T3i file using VLC player and discovered that the actual frame rate before converting to ProRes is 29.97003. I had no way of knowing this before since every other software that gives specs…tells me it’s 29.97. Could this minor decimal be throwing me off?
If so…what’s the best way to convert 29.97003 to 29.97?
