When I import a particular .mpeg file into DVD-Lab Pro, there seems to be a problem with the demuxing. The video .mpv track ends up with a duration of 23:55 and the audio 23:56. This means that, when authored, the sound slowly gets out of sync.
What is people's advice on how to avoid this? Do I need to process the audio in a different way?
Most of assets I have imported in the past have not had this problem...
Try authoring anyway and checing the result. I use DVD Lab ALL THE TIME, and its quite often that i see something like that but I rarely ever get sync problems (unless there was sync problems with the MPEG beforehand). In a lot of cases, NTSC video and audio have very different lengths, often with DVDLab showing about 6 seconds in the difference.
Thanks. I have tried authoring and it defintely is a problem. The audio gets slowly out of sync. and by the end of the movie (25 mins), it is about a second out of sync. :(
I can play the mpeg in pinnacle studio 9 or windows media player and the sound sync. seems fine there, the problem just comes in when i de-mux and author. I just assumed the different times of the .mpa and the .mpv was a clue.
