Beginners Guide To Ripping With Gordian Knot

Sound problem. There is something wrong with the Englsih AC3 stream which is on the DVD. I tried 3 times to encode it right, but all 3 times the video came out OK, but without any audio.

Then I tried to convert to mp3, which failed. Here is the encoding log of it:

Code:

Does the audio play fine when watching the DVD on a standalone?

Slayer

Yes it does, also the AC3 file plays fine when opening it with VLC.

elchupacabra

I think you should demux it and do the encoding without GordianKnot.

1.) Open video in VirtualDub (not Mod!).
2.) In the menu select Audio->Direct Stream Copy
3.) In the menu select File -> Save wav... (enter as filename: dvdaudio.ac3)

Slayer

OK, so I should make the rip with GK, then kep that file, then mux it with VirtualDub the way you describe, right?

elchupacabra

What I described above is a DEmuxing procedure. Meaning splitting something up. In this case, getting only the audio track from the file. But I just noticed that it won't help you, because it is not what you need.

I guess you already have the audio in shape of a separate ac3 file, because of the DGIndex procedure, right?

Obviously there is someting wrong with the GKnot and/or the tool GKnot uses to transcode audio files.

So what I suggest now is:

1.) Encode the video without any audio (with GKnot, MeGUI, VirtualDub alone or whatever) - pay attention of the filesize you enter! Or if you have already encoded it, then remove the junk audio GKnot added to the file with VirtualDub for instance. (Open the AVI, Select in menu Video -> direct stream copy, Select in menu Audio -> no audio, Select in menu File -> save as ... and save it as an AVI file, should only take a few minutes)
2.) Now add the AC3 file with VirtualDub manually. (Close VirtualDub, Open it and open the AVI without the audio, Select in menu Video -> direct stream copy, Select in menu Audio -> From file -> AC3 audio..., Maybe change an interleaving values and add a delay if needed - look at the AC3 filename DGIndex gave you - and Select in menu File -> save as ... and save it as an AVI file, should only take a few minutes)

Check the final file. I hope this works.

I'll just encode the video at 746-255= 491 MB.

Mmm, the VirtualDub thing tells me the following:

elchupacabra

Do you have the AC-3 Audio Compression Manager for Windows installed? http://www.free-codecs.com/download/AC- ... ressor.htm

Slayer

I installed it just now. What to do with it?

RedVeil

Installing is all you have to and can do with it. Does it work now?

Slayer

Ah, I have to retry with VirtualDub? OK, will do and I'll report back later.

Slayer

OK, I installed the thing by rightclicking on the ini file, as described on the website. However, the same thing is happening as before, I get that error message I posted above again. Any suggestions?

elchupacabra

You could try the same steps in Nandub instead of VirtualDub (are you using the latest version?).

RedVeil

Check if the AC3 codec has actually been installed by using the windows control panel.

Slayer

It is in my programs list in the control panel. It is called AC3 - ACM Codec. That is correct, right?

I didn't have VirtualDub before this problem, so I recently downloded it. I assume it is the latest version. It is version 1.9.4.0.

When selecting the AC3 file with Nandub, it gives me the following message

and then when I choose direct stream copy, and then save as, it goes on saving without any audio.

elchupacabra

It really looks like the AC3 file is damaged. You could try another DGIndex pass to get the AC3 again or maybe something like this might help: http://www.videohelp.com/tools/AC3fix_GUI

Slayer

Another DGIndex pass didn't help, the results were the same.

I got Ac3fix, but I don't know what to do after clicking Process File. There is no new Ac3 file showing up. selected the presumable damaged AC3 file as input, chose a new name for the output and then clicked Process.

junkboy

Guess you could try muxing it with VirtualDubMod as a last resort.

elchupacabra

Maybe this one: http://www.repairvideo.com/download.html

Slayer

VirtualDubMod goes and does something, but after saving the avi as a new file (parsing and everything is done), the new avi is 32 MB bigger, but still soundless.

I "repaired" the AC3 file, but VirtualDub still gives me the same error message. This is starting to look grim (not for the movie, it is actually a pretty bad movie anyway

)
