Time delays in wav from VobBlanker/DGIndex/HeadAC3he

I’ve been using this guide to edit my Vob files: http://forum.videohelp.com/topic338866.html

Initially I applied the method to my original VOBs and it worked fine, but I didn’t need all the VOB and given the run times I decided to cut the VOB first with VobBlanker, and only then apply the previous method.

The problem is, the video starts to play from time=0, while the audio, wav-format in particular, starts to play from t~=23 minutes, which is where cut it on the original VOB. If I extract to AC3 (using DGIndex), it plays fine on VLC, but when I convert it to wav (using HeadAC3he), the delay reappears. And for some reason when I decode to wav directly using DGIndex, the program run normally, but no wav-file is created.

Also, my VOB audio only has 2 channels, so if the wav-decoding worked on the DGIndex, then should I just use that instead cc3 first, and then the to wav using HeadAC3he as per the original guide (why did the author go through that extra step?)

Thanks in advance.

What is your goal? Are you trying to edit a single VOB, by converting to avi ,edit then convert back to VOB?..You could do that with an MPEG editing tool,or if just simple cutting a complete DVD source use DVDshrink’s Re-author mode with Start/End feature…

I don’t use Premier Pro,like in the guide, but if you already have a VOB on your HDD,then I would just use something like PGCDemux to extract both your video and audio streams, no re-encoding and it will save you those un-necessary steps…I’d use DaudioK or ac3Tool for ac3>wav…then load your new .m2v file and wav audio in Virtualdub…If creating an avi is your goal of course…

Goal = trim and clean up a copy of a low quality DVD (made from an old VHS tape), and then convert to avi.

The original DVD image consists of 4 VOBs (+ifo/bup) worth about 2 hours of video. I want only want 24 minutes of that, which belongs to the first 2 VOBs.

You could do that with an MPEG editing tool,or if just simple cutting a complete DVD source use DVDshrink’s Re-author mode with Start/End feature…

Thanks. I just installed DVD Shrink and the re-auther method worked fine - I’ll return to this thread later. Need to test out the new VOB first.

By the way, what’s up with DVD Shrink? I hadn’t installed it before because it hasn’t been updated in 4 years, which is a life time in software design, yet somehow that tiny 1 MB program still gets recommended all the time… Why? Isn’t there a more up-to-date alternative to it?

I’ll look into those. I’m not using Premiere Pro actually. For now I’m still trying to extract the audio so that I could edit it with MAGIX Audio Cleaning Lab (v12)… I was going to use VirtualDub (or maybe Cyberlink PowerDirector or something) for the video, which could use touching up too… Then compress it into avi (Xvid MPEG compression)…

DVDShrink ,while no longer updated,is a valuable tool in my arsenal…
