VOB to AVI (Lagarith lossless) Audio Out of Sync

[Eva-Unit01]

Recently I ripped 2001:ASO to a single VOB file (file splitting set to none in DVDDecrypter). Whenever I play the VOB file in VDM the audio is out of sync. When I encoded the VOB to a lossless AVI file and tried to play it in VDM, the audio of that file too was out of sync (gets progressively more out of sync the further the film progresses).

So my question is: how can I either make the audio of the lossless AVI file be in sync from the start or manually fix the audio problem afterwards?

Try using DgIndex and AviSynth's Mpeg2Source()?

How do you decode to MPEG2 in Dgindex?

You make a D2V project file and use it in an AviSynth script together with DGDecode.dll and MPEG2Source to frameserve the video to the encoder. If you'd bother to read the included documentation, it's all explained very well.

D2v made. I have it opened ready to encode in MeGUI. 2 questions: 1. can I encode the mpeg2 directly to an MKV (x264) and 2. I can see the combing artifacts from interlacing clearly, which deinterlacer do you recommend? I'd prefer one that is comparable in quality to TempGausMC but much faster. Yadif maybe?

It most likely doesn't need deinterlacing but an IVTC. That's if you can't use Forced Film in DGIndex and get a 23.976fps D2V to begin with. Again, the included docs explain when to use Forced Film rather than the default Honor Pulldown Flags.

And yes, you can encode to whatever you like from that script.

Use Virtualdub 1.9.X-test27 with external encoder to create x264/aac MKV.

Here is the link for Virtualdub 1.9.X-test27...

and a guide to use the external encoder...

I use...

video encoder - x264.exe
audio encoder - NeroAacEnc.exe
muxer - mkvmerge.exe (for mp4 - mp4box.exe)

It seems that it did need IVTC. After selecting 'force film' the artifacts were no longer visible in the MeGUI script preview. Question though, if the avs script automatically included the command "#deinterlace" even thought the problem was in fact the need to IVTC, not deinterlace and I already started the job with that command, will that reduce the ammount of frames further and wreck the fps?

Anything after a pound sign in an AviSynth script is a comment, it is not executed as part of the script:

Mpeg2Source("filename.d2v") # text to the right of the pound sign is just a comment
# you use comments to remind you what you're doing in a script
# the following line flips the video horizontally
FlipHorizontal()
#this is the end of the script

[manono]

First, Forced Film isn't the same as a full IVTC. When running the Preview in DGIndex are you getting 100% Film in the information window? If not, using Honor Pulldown Flags followed by an AviSynth IVTC (Decomb, TIVTC) will probably be a better choice.

I don't use MeGUI, but any line beginning with '#' in an AviSynth script isn't used. It's ignored or, to use the correct term, 'commented out'.

Can anyone help with THIS?
