Time shift out-of-synch video/audio

RickD wrote on 5/19/2007, 12:53 PM
I have a very large mpg file that I would like to create a DVD from. The problem is that the video and audio are out-of-synch by about 0.12 seconds. Is there a way of fixing this problem in DVD Architect? In Vegas I would un-group the tracks, shift one of them by 0.12 seconds and then re-group them. I am trying to avoid rendering a duplicate mpg file from Vegas just to correct this minor problem.

afaik, not with DVDA. However, in so much that DVDA would prefer that you present it with separate audio and video files, take the MPG into Vegas and make the necessary shift - encode only the audio to a new file, then when you take the MPEG into DVDA, specify that it's to use the new audio file rather than what it finds muxed in with the video.

If it helps...

2 alternatives I've done before:
1) as Scott suggested but with the addition of DgIndex & VFAPI. Using DgIndex on the mpg2 video, then using VFAPI on the .D2V project file you get, lets you preview the mpg2 to verify sync in Vegas rather than trying to do it just by the numbers.

2) If already rendered to DVD demux use PgcDemux. Import the new .m2v, your AC3, Subs (if you have them), & the celltimes text file into Muxman, setting the appropriate delay. Test & adjust if necessary. Use VobBlanker to replace the existing VOB files in the title-set with the Muxman rendered version. Use IfoEdit to set the Sub colors if used.

VideoReDo is a nice little utility that can re-synch video/audio without transcoding.
