My audio settings do match that of the audio clips. They are 24-bit @ 48KHz. I know that auido is never measured in frames per second and I was quite surprised to read the 23.98fps in the file name. Therefore, the only thing I can come up with is that they were mixed at 5.1 and rendered out at 23.976 (even though my source footage with no audio is at 24p).
Do you think it would be preferable to go into Media Encoder and conform the clip to 23.976?
I am feeling I need to go back to the client and say that the audio is just not in sync and needs to be re-procesed out.
Thanks for your help!
