Video/Audio out of sync only after burning DVD...why?
on Jul 26, 2005 at 1:43:01 am

As you can see if you read back a few days...I've been trying to burn a DVD. I am using Premier Pro and Encore DVD 1.5 I tried forever to get chapters to work smoothly w/ 8 different timelines and finally gave up. I tried for a while to figure out how to put in chapters in Premier and finally gave up. I ended up putting a 4 hour Europe video into Encore as one timeline and placed the chapter markers in Encore. Everything seemed to be running smoothly. I previewed the DVD in Encore and everything worked. I then burned the DVD letting Encore figure the encoding compression level on its own. I then popped the DVD in my set top player and it worked! Everything worked smootly and the chapter skip worked fine forwards and backwards.

Then after watching a bit of the video I noticed that toward the end of the DVD the voice and video were out of sync about 1/2 a second...just enough to be annoying. I went back to my timeline in Encore and sure enough the audio line was a bit longer than the video line. I redid the whole thing and made sure that the lines were exactly the same...and reburned the DVD. When the DVD was done burning I checked and the timelines no longer matched...the audio timeline was once again longer than the video timeline. THIS HAPPENED AS I BURNED THE DVD! How could the DVD burning change the length of the video or the audio? So now I have two DVDs w/ out of sync issues toward the end.

Any ideas?

How are you exporting your video from Premiere Pro? My guess is that you're exporting as AVI, and the problem is occurring when Encore transcodes it into MPEG-2 before the burn. This could likely be solved by changing your transcoding settings, but you could also make it simpler by exporting your video from Premiere Pro as MPEG-2.
