This is my first post although I've been a reader of these forums for a little while. We've just finished producing a drama which stands at 19:57, shot in HD 1050 25fps. It has a stereo 2.0 soundtrack and also a surround sound 5.1 track. I'm putting both audio tracks onto the DVD as choices for the user.
I've exported the audio and video through compressor to get the DVD m2v and ac3 files. The 5.1 ac3 track I created using 6 AIF files that were exported separately from the timeline of FCP and assigned to their relevant speakers in compressor. The 2.0 track was made through compressor as well - as I normally would. All of the assets, the video / 5.1 / 2.0 all came from the same timeline and from the same in/out points, so there shouldn't be a problem with the audio syncing as it plays fine out of FCP. But when I've put the audio and video into DVD Studio Pro and burnt a DVD the audio becomes out of sync. To combat this I tested how many frames out of sync it was, by moving the audio track 1 frame at a time. I discovered that it was 2 frames out, but why? It all synced up in FCP and I've never had this problem before using DVDSP / Compressor / FCP.
Can anyone shed any light on this issue, have you experienced it, or do you know a fix?
