@Kwag,

I'm using this method now too, and the results are awesome. IMO this is a HUGE improvement! I'm now re-encoding the audio for Black Hawk Down and I can't wait to check it out.

Can the AC3 file be dumuxed with earlier ver of DVD2AVI or just the latest release? Also can this method be used with .AVI captures?

thanks a lot,
ren

Hi Ren:

The AC3 can be demuxed with ver 1.76 of DVD2AVI. It just extracts the file from the DVD to your HDD. Then headac3he does the magic
For AVI captures, , haven't tried that! I don't think a captured AVI can have embedded AC3 audio.

although the sound is great- the audio is always a little ahead of the video. I've tried different movies with different templates and the result is always the same. It seems like DVD2AVI is calculating the wrong delay or something. Also its in sync when I play it on the computer. I'm completely stumped.

That's weird ren. If it plays in sync in the PC, but not in your standalone, it seems like a mux problem. How did you mux your video/audio files?

hi Kwag,

I simple-multiplexed in tmpgenc as mpeg1 non-standard. The sync problem is weird because it's not consistent at all. it starts in sync then there's delay- on another disc, the audio is ahead of video. I'm encoding "Black Hawk Down" for the fourth time using avisynth IVTC procedure instead of FF in dvd2avi to see if that has anything to do with it.

Also there is a very slight chance that when I encoded the video only, I might have had mpeg1 system checked- I don't know if I made this mistake but could this cause the problem?

thx
ren

If you had MPEG-1 system instead of MPEG-1 Video CD ( non-standard ), yes!, that could have been the problem.

I've made about a dozen coasters of "Black Hawk Down"- everyone, the audio is out of sync but they play fine on my computer- so I've come to this conclusion: my old JVC pro-logic receiver is having trouble decoding the audio which I encoded at the highest bitrate Headac3he would allow.

Is this a plausible explanation Kwag?
I'm grasping at straws here

WOO HOO!!!!!

I just tested my kvcds on a newer sony 5.1 receiver and audio+video completely in sync and unbelievable sound.

Now I'm going to dump my JVC RX-717V which I purchased many moons ago and go shopping

I bought an RCA RT2280 a couple of weeks ago, and we're having a ball with surround sound too!

headAC3he uses azid just like Besweet but uses mp2enc to encode the audio. I like it better than Besweet. It's faster. And headAC3he has the surround 2 mode that I believe Besweet doesn't have.

OK Guys,

I've now done the same thing, using HeadAC3e to encode my audio and keep the surround info, but a few questions.

Do I have to mux the audio & video back together before I plop them into DVD Moviefactory or Workshop ?? I've done this and it seems to work.

But, I sort of remember reading somewhere that I could keep them seperate and if they were named properly, loading the video portion into the authoring package would cause the audio to be automatically muxed in when the image gets created.

Is this true? If so, what do I have to do ?

Or, have I just been spending too much time experimenting with Vanilla Coke and Rum ???

Thanks

ok here is EXACTLY what was causing my audio/video sync problem:

1. loaded .avs video source in tmpgenc
2. selected output file name
3. set stream type to video only
4. loaded KVCD template <<<<<< template would automatically change stream type setting to SYSTEM (VIDEO+AUDIO)
5. then I began encoding not knowing that the stream type had changed

I think in this case, the template should be loaded FIRST

I just do this:

1. Load the .avs file.
2. Load the template to be used.
3. Click under Stream type "Video Only"
4. Make any adjustments, output file name, etc. ( if necessary ).

Encode......!

I keep jumping the gun thinking the problem is solved but it's not and it's driving me nuts!

here's the problem: the audio is a lower pitch (male voices sound similar to Andre the Giant) and it is delayed --but the damn cd plays fine in my computer! My player is a Sony DVP-NC600. dvds play fine. What could possibly cause this? i've tried muxing with BBmpeg and TMPGenc both exact same results.

what's going on here?

AHAAAAA!, that bit me about a week ago too
You forgot to check "Resample to: 44.1 Khz" in headAC3he HehEHEHE

The question is the same as the subject. If AC3 is the one, what is the set up in DVD2AVI (v1.76) to extract a AC3 file instead of WAV file? The following is my working flow:

Smartripper-->DVD2AVI(v1.76)-->FitCD-->VirtualDub(adding subtitle)-->Tmpeg.


This is for Kwag or other volunteers, the NEW template's source aspect ratio is set to 1:1 VGA, did you do it on purpose? Previous templates were set to 4:3 NTSC (704x480), what's purpose of this change? Thanks.

So that you choose the correct aspect ratio you need, depending on your source
Actually, if you use an .avs script, you can leave it at 1:1. AviSynth will take care of the correct resizing, and your output will be correct.
For AC3 in DVD2AVI, you choose 'Demux" instead of "Decode". The AC3 file will be extracted by DVD2AVI. This is the file you process with headAC3he. Use the same procedure you're using, Smartripper-->DVD2AVI(v1.76)-->FitCD-->VirtualDub(adding subtitle)-->Tmpeg, and after that, encode your AC3 audio file with headAC3he and mux the video/audio with BBmpeg. You'll have a prefect KVCD with Dolby Surround and perfect lip sync audio!.

Is it normal to take an hour to convert AC3 file to MP2 (PIII-800). Also, under the Option button and under "downmix type" should I select surround or surround 2. For "Channel Mode", I believe I have to select "dual channel", right? What about the "PsyModel"?

I haven't been checking that, do I need to? I thought we wanted 48 instead of 44.1. I haven't had any problems with the sound by not checking "resample".
