Can I manually adjust audio/video sync problems?

[Xenogear900]

Is there a program that makes it easy to address sync problems? Like if I had the kind of timeline thing used in programs like Windows Movie Maker. Is there any program that I can kinda fix sync problems in? I'm VHS capturing on a Adaptec GameBridge 1410.

What type of file ?
What compression (video and audio) ?
What sort of sync problem ? Out by a continuous amout ? Drifts out over time ? Drifts out and back ?

Its captured as an MPEG2, It seems to be a continuous amount sync problem.

https://forum.videohelp.com/viewtopic.php?p=1625975#1625975 will show you how to find out how much out of sync your audio is. You could also try using SyncView to create a new audio track that has the correct delay in it.

Note : The second part of this post - that uses virtualdub to change the skew - cannot be used for mpeg video.

If you are capturing to later author for DVD, have a look at your authoring application, as it may also allow you to adjust for audio delay.

there is a virtual dub mpeg version that I used to fix my audio sync problem-brilliant,just save the audio file when fixed as a wave file, and then use with the original mepg file

I always use MPEG Video Wizard for determining the delay value.
Right-clicking audio or video stream on time-line gives a 'location and duration' menu for directly typing a value (seconds, frames or timecode) for previewing the adjusted delay. After you get the right number, the rest is easy (unless there was also difference in video/audio duration) - you either insert the corresponding ammount of silence in the beginning of audio track (using any sound editor) or cut off this time value.

Hello, Terry B.!

Could you please elaborate on the "Virtual Dub MPEG Version"? I am a bit confused. If it accepts MPEG files directly, why saving the corrected audio file separately?

I found I only needed to save the corrected audio file as saving thevideo file in this software converts it to avi, a waste of time.,all you want is the audio corrected.
