Out of sync audio all too often yet again.. -AC-3 Encoder

Subject:Out of sync audio all too often yet again.. Posted by: AVERAGEJOE Date:7/31/2004 8:05:19 PM I have 2 camera angles miniDV and DAT audio. All audio/video in VV timeline is lined up 100%. Around 45 minutes I gradually lose sync when previewing the DVDArch-type mpg with it's corresponding AC3 audio in DVDA. When I go back into VV, and render only 30 seconds of the part where it seems to lose A/V sync, it is 100% fine in DVDA...it is only the hour-long version that loses sync. Is there REALLY no fix for this??? WHY does it not hold sync if it is PERFECT on the VV timeline?? Even if I try to compensate with Ctrl-drag-stretch, it is the same issue

The only way it works (BIG waste of time) is render to a new track (in DV format uncompressed) and try to line the audio up again because the new DV format track that VV created is out of sync. Control-stretch does the trick to correct it but WHY do I/we have to waste 3 hours of unnecessary render time?

There has to be a logical fix for this, for the problem happens too often to too many people. I am not a software design expert, but if the audio peaks line up from different sources I see no reason why they can't ultimately line up in the finished product without going around any faults DVDA has.

Try going into your 'Project Properties' and then go to the 'Ruler' tab. Change to "SPMTE Non Drop (29.97 fps, video) My sync issues disappeared after I did this. I've sync'd up Sony Dig 8 and Canon Hi-8, without any problems. Stayed in sync for the entire duration.
