Sync problems when cutting and pasting from HD sequence to NTSC Sequence
Alright, this is very strange. I am assistant editing a doc show. We shot the interviews on the HVX200, 24p using p2 cards. Our editor has been editing on a 720p60 sequence. Only our interviews are in HD, the rest is NTSC transfers from DVD’s and tapes of archival material
Now, we are getting ready to output and have decided to transfer this sequence into an NTSC sequence so that we can make an output that will be letterboxed, etc. We do not have HD decks.
When we cut and paste the sequence from the 720p60 sequence to the NTSC sequence (720 X 480, 3:2), some of our interview clips go out of sync by 1 frame. There are also moments where there is a one frame space in between clips. This happens sometimes, not all the time in the sequence. It also does not happen in a pattern. It doesn’t happen until 2 minutes or so into it, then some of the clips stay in sync, and others, throughout the sequence go off by one frame.
I tried cutting and pasting just one of the clips that goes out of sync from the HD sequence to a new NTSC sequence, same thing happens. I am completely baffled by this. Any help would be tremendously appreciated. Thanks.

I have had a similar problem. I think it is frame rate related.
My solution has been to export the HD sequence as a self contained movie. Then, re-import the movie and insert that into the NTSC timeline.good luck!!

I’ve been running in to this too when going from 720p60 to NTSC. I think the problem arrises when you have a clip that starts on a * frame (like 1:00:02:00*, for example) When that happens the audio seems to be off by a frame.
I’ve been working on :30 spots so I’ve ben fixing it manually. I would suggest bouncing out an aiff from your HD timeline if you can’t go through each shot.
