Audio question in VirtualDub

[dcapp1]

I am trying to extract the audio from the movie source I will be converting to mpeg, but about halfway through the extraction an error pops up that says ACM reported error reported on audio decompress. Can anybody tell me what this means?

[dcapp1]

No one knows of this error?

[secretagent]

why not mention what you are using to extract with.

[dcapp1]

Sorry, I am usin VirtualDub.

I get wierd things sometimes with audio in virtualdub. You may want to try loading the audio into tmpgenc and then select File - Output to File - WAV. I've had better luck extracting that way, when virtualdub complains.

[secretagent]

to extract audio with virtual dub load your file then go to audiio, set it on full processing mode. then in audio go to conversion. set your aduio for high quality then select bitrate and stereo options, then go to audio compression make sure that ot is pcm, no compression. then go to file menu and check save as wav. if you don't do this then vdub will extract your acm and just put a wav extension on it with out changing it from acm3.

secretagent,
No offense but where did you get that info? The only way you can extract an ac3 file from an avi in VDub is select direct stream copy, go to save wave, "save as all files", and rename the file extension to .ac3, then save it. Going to full processing mode in VDub and trying to save as a wave is going to do nothing but generate an error message.
dcapp1,
After extracting the ac3 file your going to need another application to convert it to a wave. I suggest using HeadAC3he for the conversion. You can find it at: http://darkav.de.vu/
Go to the download page and along with the main application make sure you download the correct dll's for the type processor in your system. It's pretty straight forward after that.

[secretagent]

kayfam you are right . I was wrong. I must have been high.

[Bel]

I still say just do it in TMPG, and save yourself a couple of steps. Assuming you have an ac3 codec installed.

Not true, if you have the correct AC3 codec's, Vdub will easily convert from AC3 to uncompressed.

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

Works just fine, but obviously not on your system

So does Vdub AC3

Where can I get one of these AC3 codecs?

KingJohn,
You are a wise old sage who has been browsing these forums a lot longer than I, but on this topic we part company. As you suggest some people might get away with using VirtualDub to convert the ac3 file, but I'm sure if we ran a poll more often than not the opposite would be true. Without statistics to back up my claim it's my word against yours, but I still stand behind the method I outlined. VirtualDub is a wonderful tool for most things, but in this case I wouldn't say it's the preferred tool for the job. I'm also going to say that HeadAC3he may not be the best to convert ac3 as compared to any other program since it's the only one I've ever used, but in the last 2 months I've converted at least 50 files without one screw-up. The resulting output when combined back with the source video has been flawless. I've had 0 (zero) issues with audio sync and I've yet to have any other application (i.e. TMPGEnc) complain when using the processed wave file. We all have different methods trying to accomplish the same task and this is mine. It works, it's that simple, and as my signature suggests, if someone has a better idea I'm willing to take that into consideration. Just for the record I do have the ac3 codec filter installed and I've always had lousy results going that way.

KingJohn,

What would a poll prove ?

It will prove that many people have problems and come to this site to for help, more often it’s a matter of installing a codec. So a poll would prove that the vast majority of people don’t have the means of encoding with the many different types of OS/installed programs.

Different PC, different OS, different codec's, trial wear programs, hacked programs all add up with things working for one but not another.

If something does not work, search around, in this case download other AC3 codec's, Nimo codec pack has a basic AC3 codec, there are many others. (Voxware Pro)

There are many people on this forum that say you cannot load a movie into TMPGEnc that contains AC3, some even say it wont even work with MP3. or MPEG 2, what would that poll prove ?

Loading a VOB file (Its not shown in the file type list) (*.*) will load it, what does that prove ?

I agree that posting different methods of doing the same job is great, but when they start off by saying that something wont work, because it wont for them......

[KingJohn]

Where can I get one of these AC3 codecs?

Best place is to search Kazaa, lots on therre type "AC3"

See also the above link for other methods.
If AC3 wont work in Vdub, why is there a Vdub AC3 ?

KingJohn,
I've been following your posts with great interest not only here but also elsewhere in the forum. You can't stand not getting the last word in!! Before we turn this into a flame session lets just agree we disagree. Continuing this thread is doing a disservice to all who are seeking some advice and wasting server space. Let us both work to try and help others seeking advice and may one of our ways work for them.
Peace.....

[ya_jai]

To know more methods and/or problems is better than know only thing. One method might work for one but not for others. One'd prefer what he/she used to.

What am I saying here, I'm confused

[dcapp1]

My original question wa about ACM, not ac3. Are these the same things because there are no ac3 files associated with my movie. I have tried different ac3 codecs and vdub still will not complete the extraction. I tried using the dolby ac3 decoder, and it will not work because my move has no ac3 file associated with it.

[KingJohn]

Sorry dcapp1, my reply was to someone who thinks because it wont work for him it wont work for anyone. You are right I did not catch the ACM at the top of the page.

There is a confusion with the term you use, ACM (Audio Compression Manager) are stream interface drivers, and are controlled by the device manager.

These could be MP3 codec's through to the humble WAV codec. So if you have got a ACM error, it would be telling you that a particular audio codec is missing (MP3 ACM codec etc)

Fully functional Win32 ACM/DShow codecs

DivX audio (WMA)
MS ADPCM
MPEG layer-3
IMA ADPCM
MS GSM
MSN AUDIO
MS GSM
VoxWare
ACELP
Intel Music Coder
Vivo G.723/Siren Audio Codec
ALF2 0x1FC4
DSP Group TrueSpeech(TM)
VoxWare RT24 speech codec
Lernout & Hauspie CELP and SBC codecs


ACM reported error reported on audio decompress.

The codec failed !
Usually caused by junk in the AVI

KingJohn,
You can't stand not getting the last word in!!

If you mean when someone has a go at me I reply, then yes I don’t take crap from anyone !

And when I see crap being posted I also reply to that !

Let us both work to try and help others seeking advice and may one of our ways work for them.

You are free to post what ever you wish in this forum, I have no wish to argue with you or any other "newbie's"

If the Avi file is corrupted, can any one steer me in the right direction for a goo back to the future download?

Hi

There are quite a lot of problem AVI's most can be sorted with a simple scan in Vdub for junk frames. However you wont get anything to work unless you have all the codec's installed. If you have DivX 3.11 Alpha installed, but download a AVI that was made with DivX 5.02, then you wont be able to do anything with it.

You Need them all !

In this scenario, it seams you have a missing audio codec, I think a lot of people recently have had this problem, it seams it could stem from the new Nimo Codec Pack.

Load the AVI into Vdub and select File > File information
This will tell you what the codec's are for both video and audio, if any of them say unknown you have a missing codec.. Go Get them all !!!!

[winny22]

i opened my movie file in v/dub and everything was there except..................compression.....unknown (tag 2000) i cant rip the sound out with v/dub or db poweramp what codec am i short thanxs

[KingJohn]

Am I making double posts in this forum, or is there someone else with the exact same problem.

Load the AVI into Vdub

Video > full processing mode
Video > compression

This will list the codec's you already have, now install the ones you dont have !! Look for DivX, also look under audio for MP3

[dcapp1]

Hi, I finally got the audio problem fixed by running the avi through divfix, but now when I load the video source into TMPEnc there is no picture. it encodes a bunch of garble. Ive had this problem before, does it have to do with running a avi through divfix?

[KingJohn]

So divfix, fixed it for good then Its not a program I would recommend.
If the AVI now plays ok from start to finish, then it could be the DirectShow priority settings in TMPGEnc


Select options > environmental settings
click the VFAPI plug-in tab
right click the "DirectShow" and select higher priority, do this several times until its at the top with a value of 4
