HI Dan,

Thanks for the reply. Yes, I realize this is odd. I am doing a side by side, video and slide presentation so I am looking at a MUCH wider image than it is tall. What I would like to do is make a 16×9 SD DVD (with letterboxing of course, but also have a much smaller 4:3 image with letterboxing.

What would be the best thing to do? Basically I am looking for a way to encode it with the letterbox matte both for 16×9 and 4×3.

I also did another test to rule out the QT reference movie. I exported the OMF, and brought it into STP. I didn’t touch the clips at all. I then exported those tracks as an aiff mix and brought them back into FCP and put them into my sequence. They are out of sync in the same places as they are in the STP and PT projects.

Okay, I just exported an aiff out of FCP and brought it and a new QT movie (.h264 with a hard frame rate of 23.976, audio Linear PCM 48 kHz 16 bit) in to Pro Tools and STP and they run perfectly in sync.

The omf, is still out of sync. And yes, the degree of out of syncness (is that a word?) varies just as Michael C. describes. Some are behind, some ahead, and looking at it in pro tools, they are sometimes off by 1/4 frame, and other times by over 2 frames, and anything in between.

Michael C. describing this, is the first I have seen of anyone else having this problem. It has to be some setting that we are missing. Something in the creation of the OMF. Both PT and STP do the same thing, so it’s not those programs.

I love a mystery, but I am running out of time, and I can’t think of anything else to troubleshoot this that I haven’t tried already. Advice????

Hi jerry,

The QT is self contained. By reference movie, I just meant video and audio reference for sync.

Michael,

I have also never had a problem with an omf. In fact, this is the second short film in a series that i am doing and I used the exact same camera and system and had 0 problems with the export and import on the first one.

I tried a few different reference movies, I tried compressing and I also tried just sending it as a quicktime movie with the current settings, just to make sure something wasn’t happening in the conversion. I also tried one by setting the frame rate-In FCP 6 it doesn’t give you a 23.976 as a preset option, you have to type it as custom frame rate. I also did the reference movies on two different computers, just to make sure that it wasn’t my computer. I had the exact same problem every time. Whether it was a straight QT or an .h264 crunch. Each time it goes in and out of sync.

I would also understand if there was sync drift because of frame rate issues, but it locks dead back into sync on a cut and then back out on the next one. I have never seen that before.

I am going to export an aiff and bring that in. This may narrow it down to the omf.

Any other ideas what the culprit may be?
