Audio problems w/ certain avi files in virtual dub

[I$]

When i sav as wav in virtual dub I get this error message, " requested audio compression is not compatible w/ input form. Check sampling rate & channel count.....etc, etc." The avi files that seem to do this are the files that have a bit rate of 448kbps vs. the files that do work with bit rates of 145kbps and a audio format mpeg layer 3. I have NIMO, all the DIVX 3,4,5 and tmpgenc as well. I use NERO to burn and watch vcd on my standalone dvd sony.......A beautiful mind worked and so did Jay and Silent Bob. I can't get two others to work right! I'm going to break my computer with my head !

Don't just save the audio as it is, save it converted.

Audio > Full processing mode
Audio > Conversion > 44.1Khz
Save WAV

[I$]

i've done that already and have some movies that do work, but only certain avi files I dl are not letting me save as wav. I've converting audio files to wav files and used tmpgenc to encode movies to cdr's and watched them perfectly on my dvd. I scrolled through the forum and another person suggested i reinstall divx3,4, and 5 and even NIMO codec, but every time i unistall and then reinstall i seem to get more errors and lose more!

Then you must have a codec missing for the Audio, Nimo provides AC3. If you click properties on the AVI does it tell you what codec is used, or in Vdub file > file information. Does it show a audio codec you don't have, like AC3 ?

Well Nimo says to un-install, but I never do. You would soon know if it wanted to overwrite something.

[I$]

I thought i might be missing a codec so i unistalled nimo and then reinstalled it. This time i dl everything on NIMO and no errors, but I'm having the same error telling me abouth the compression and to check the sampling rate and channel....etc, etc. I checked the properties of the avi like you said and the files I have that worked vs the ones that don't have low bit rates and the ones that are giving me the problem have high bit rates like 400+Kbps and nothing for audio format. Now that I'm checking the ones that worked did say something like ac3 or mp3 for audio format and now they don't.......weird......i think i'm going bug-eyed!

The non-working files almost certainly contain AC3 audio which vdub can't handle. See my earlier post.

[I$]

i've been doing some reading and have found something that might work.....headac3he after i virtual dub, but this dl is .rar and i don't know how to open it.?

[bugster]

to pen a .rar you need winrar, do a search on google.

[I$]

now w/ regards to headAC3he it keeps telling me " can not get vorbis interfaces and get a new updated version" but that is the only version i found through VCDHELP.COM

I know i'm getting warmer

I$

[bugster]

OK, that suggests to me that the audio in your trublesome avi is ogg-vorbis. Do a google search and you will find the codecs needed.

KING JOHN YOU DA MAN!!!!!!!!!!! everything works great now!
now i need the dvd case insert for the movie cover....know where those are? I'm planning on a collection

goldwave to the rescue

[KingJohn]

Well glad you got there, so many codec's out there, I guess I could make a movie with one that nobody else has. Yes the covers are about, but not searched for any lately, try http://www.mega-search.net/

The non-working files almost certainly contain AC3 audio which vdub can't handle. See my earlier post.

Not always

And Vdub can handle anything, provided you have installed the files it needs, the only thing it does not like is variable bit rates, which are cured simply by converting the audio to uncompressed 44.1Khz (VCD audio)

[bugster]

KingJohn, please correct me if I am wrong, but isnt AC3 generally variable bitrate? Or at least in the case where it is a direct DVD ripped AC3 stream. In this case the usual procedure (at least the one I use and have read about elsewhere) is vdub, audio->direct stream copy, save as wav, then use Headac3he to convert to wav.

And a good place (but not the only one) for DVD covers is:

http://www.cdcovers.cc/

Lots of advertising and occasional popups though!

[KingJohn]

Why would you want to save out the AC3 then convert it later, when you can save it out already converted in Vdub ?

Audio > full processing mode
Audio > Conversion > 44.1Khz
SAVE WAV

[bugster]

I have been follwing this guide here:

http://forum.vcdhelp.com/viewtopic.php?t=91588

so are you saying tha vdub can handle AC3 OK as long as you have an AC3 codec installed? I had a divx with AC3 (several actually) which played fine in WMP and PowerDVD but vdub could not extract the audio using full processing mode, which is why I went down the HeadAc3he route. Have I been wasting my time and disk space?

(I cuurently do not have any divx's with AC3 so can't test this out at the moment!)

[KingJohn]

Well I have the Nimo codec pack installed, possibly some others, Vdub does not handle the AC3 audio, but it can be converted like I said.

As you say mostly from DVD rips
