AC3 codec/filter with virtual dub and TMPGEnc

[buzzsaw]

I have an avi video that had no sound. I downloaded the AC3Filter 1.1 and installed - the video now had sound.

I then wanted to convert the avi to MPEG using virtualdub and TMGEnc plus, but both programs don't recgonize the audio of the video just like media player did prior to the installation of AC3Filter. The AC3Filter created a program group but nothing seemed to be useful.

How do I get virtual dub and/or TMPEGEnc to be able to use the audio and/or the AC3Filter?

Thanks in advance.

Did you reboot?

If the audio is AC3 it's very likely already MPEG DVD compatible.
YOU just need to demux it.

I use this batch file:

for %%I in (*.avi) do (
avi2raw -a %%I %%~nI.raw
P:\BeSplit\BeSplit.exe -core^( -input %%~nI.raw -fix -type ac3 -output %%~nI.ac3 ^)
del "%%~nI.raw"
)

avitoraw does the demux: (download, docs)
BeSplit fixes the header of the AC3 (not always necessary, but best to just do it anyway). Should also use this if you demux using VDub, there is also a little GUI for this.

vdub uses a different version : ac3acm , not sure about tmpegenc but I suspect it's the same

I did ... didn't help. When I fire up TMPEGnc ... and select the avi only the video is recgonized - no audio

Could you please throw me a bone how to run that batch file. I am familiar w/ DOS / Windows batch files but not sure where to run the script that you have there. I am willing to try !

Another option, if you just want to save the audio (i.e. copy it) you could use avidemux . It includes all codecs, so no need for external ac3acm or ac3filter

leave the audio sidebar set to copy, audio=>save with extension (e.g. "myfile.ac3")

Or you could use ffmpeg to copy it:

ffmpeg -i input.avi -vn -acodec copy output.ac3

Curious as to why you want to convert to MPEG.

You can use VSO DivxToDVD to convert to DVD if that is your objective.

You have to buy the AC3 plugin for TMPGEnc (I know, that's a crock of sh!t). Virtualdub doesn't encode to MPEG and AC3 support is tricky.

Hey didn't know anything about VSO ... I will give that a shot - sounds easier! Does it make chapters ?

[DarrellS]

It creates chapters but doesn't create menus.

Here's a guide...

In general, your first idea was the best one. But in this case, VSO does do a really nice job.

CXD does a nice job... not the ancient BETA recommended by DarrellS. The usually recommended free, modern apps are a much better choice.

DVD Flick
AVStoDVD
FAVC 1.06

VSO DivxToDVD didnt make a Audio folder ... sigh ... try the other suggestions I guess.

First get the programs it needs, and make the paths in the batch match where you put them.

Save the batch file to a file "avitoac3.bat". Save it in a folder in you command path (if you don't know what that is, just put it in the same folder as your avi files).

Double-click on the icon for "avitoac3.bat" (or open a command prompt if you can).
It should run, extracting AC3 from the AVI files in that folder. Should take a few minutes per file.

DVD-Video format does not use the AUDIO_TS folder. It will be empty or missing. It is not needed.

Nero Vision also does not create an AUDIO_TS folder, but both Nero and ImgBurn will create one when a disc is burned.

Here is what I did (reference for other newbies and to close thread and to show I was paying attention and appreciate all responses ).

I installed the AC3Filter so I could hear the AVI - everything was cool.
I then used VSO DivxToDVD as suggestioned by DarrellS, made a nice lil Video_TS folder. I then PM DarrellS about chapters and he reminded me TMPEGnc DVD author can use not just MPEGs but DVD files too.

Used TMPEGnc DVD author - it regonized the audio as Dolby ac3 and asked if I want to use it - h*ll yeah.

Imported the chapters, made a menu, and then made the DVD folder and burnt it to DVD.

Grabbed a drink and put the popcorn in the microwave.

Thanks for the input everyone and I hope my closure to the thread will help someone else instead of just walking away with the answers but sharing our success as well as failures is what it is all about, right ?

Cheers!
