Thanks everyone for all the help!
I did just need to go from 24fps to 23.976 (changing the speed .1%). Converted it to an AIFF file as well, all in Compressor. Everything’s working (or syncing) great! Not to mention merging of clips; FCP doesn’t like merging two video clips…lol.
Yeah, when this documentary film began shooting (10 years ago!), DAT was still it. Glad we’re on to sold state and CP cards!
