Hi Michael,
Thanks for your advice. It must be the sample rate then because when I change frame rate in WaveAgent then reimport back to FCP (new file name, Easy Setup at 25fps, etc) it’s still the same problem. The audio is the same length as the other 24fps file on the timeline. The only way I’ve been able to solve the issue is by changing speed of audio to 104%, saving then reimporting. That seems to sync up, however it also merges the split mono tracks into one stereo track so that doesn’t solve my problem.
You mentioned the sample rate – if this is the issue, how would I solve it?
Many thanks,
Claire
