I had a problem with audio sync in final cut 7 several times.
Now I'm working with video at 24fps and when I import the audio it doesn't sync and the render green line appears in the audio clip in the 24p timeline but if I put the audio in a 25p timeline the green line doesn't appear.
Does anybody knows how final cut interpret tha audio sample rate?
Because an audio technician frined of mine told me that all the audio is recorded at 30 fps and I don't aunderstand anything.
And with another project, working at 25fps, the audio was interpreted as 30fps.
I hope you can help me.
Thank you very much!!
I had the same problem and what I did was changing Framerate.
Then, I quitted FCP, opened it again, created New Project, imported the audio, put it on timeline and see if it has the correct framerate. And it was :-) If not, try changing Easy Setup and restarting FCP.
