I just shot a bunch of very long interviews using the FS700 and the Odyssey 7Q+ I transferred all the footage I shot using the CD ProRes utility. My problem is that the audio begins to go out of synch on the footage after a few minutes.

Unfortunately I only archived the CD ProRes transferred footage, so I can't run the footage through the CD ProRes utility if that would be the fix.

Is there any way other than manually synching the footage in post?

Thanks for any help.
