So idet DOES report frame info to w3fdif? Of course, as you mentioned and
as I've seen elsewhere, idet isn't the most reliable, so it's not a great
solution. Still, good to know that it will work in certain situations.
Thanks!

It would have originally been DVCPro HD footage recorded to P2 cards (back
before P2 supported AVC). The only conversion of any sort would have been
the remux to MOV that FCP7 did for P2 media. Now, this assumes that my
predecessor followed the correct workflow for ingestion, so I honestly
can't say. ;)

Thanks for all the help! This has cleared up quite a lot!
