I'm Stumped! Niether TMPGEnc or VirtualDub works on AVI file

[cybersive]

Help! I have converted lots of AVI's to VCD using the excellent guides posted here and have normally been able to fix things as I encounter them by scouring the web pages but am now stumped with this problem:

I have downloaded an AVI file which was probably ripped from a DVD and I have no problem viewing this file using the Windows Media Player. I am trying to convert to MPG using TMPGEnc v2.50 for VCD purposes and I get the "can not open, or unsupported" message for the audio section.

So then I try to separate the WAV file using VirtualDub v1.4.7 and get this message- "Requested audio compression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested output."

I do not know what else to do!

My configuration:
P4 1.5 256 MB RAM 120 GB HD
Windows XP professional

Easy (?) solution to your problem - use AVIsynth to frameserve the AVI file to TMPGEnc/VirtualDub.

1. Go to http://www.videotools.net and download the latest AVIsynth
2. Install AVIsynth on your system according to the instructions in the ZIP file
3. Create an AVIsynth script (for frameserving the AVI file) and save.
4. Load the script file in TMPGEnc/VirtualDub.
5. That's it.

Let's say for arguments sake that your AVI file is called sample.avi and it is in a temp directory (c:\temp\sample.avi). Enter in the following one line of text using a text editor such as NotePad:

DirectShowSource("c:\temp\sample.avi")

Save this file in the temp directory and call it getsample.avs. Now load up TMPGEnc/VirtualDub , choose Open, then choose the

getsample.avs file. The AVIsynth .dll file that you installed sees this, intercepts the AVI frame requests, generates the frames using DirectShow, then passes those frames to TMPGEnc/VirtualDub. Those programs only "see" the generated AVI frames, not the original file.

Hope that helps.

** Apologies if this gets posted twice, but the submit just crashed! ***

I've got the exact same problem as this, so jumped at the chance to try out the suggested solution ....

.... but unfortunately it didn't work. I managed to get AVISynth installed OK and was able to load the .avs file into TMPGEnc (after I added the fps parameter to the script - it didn't work without it!). Result was the same - video ok, but no sound at all.

I'm currently in the process of encoding again using the SMPX plug-in directly within TMPGEnc.

In the meantime, anymore suggestions welcome?

You're gonna have to do some research on the file. Find out what kind of audio compression the avi uses. Some DivX movies use ac3 sound which can have more than just stereo sound which means more audio chanels than normal. You might wanna update your audio codecs and then try it. Also if you plan to demux, try demuxing the audio to an uncompressed wav. Then you can choose it as the audio source when you go to encode with TMPGEnc. You might have to convert the sound to 2-channel Stereo, 44.1-khz, 16-bit, high quality mode (using virtualdub) if it is ac3 sound...


Hope this helps...

open your avi in virtualdub
under file-->file properties
this will tell you if you've got ac3 audio
if so, search the forum for ac3 from divx
this will show you how to extract/convert your audio
if you don't have ac3 audio, under audio-->full processing mode
file-->save wav and use this wav as audio source

just open notepad, and create a small text file with the line:
avisource("c:\path\movie.avi")
save as something.avs (make sure file type is all files and not .txt)
open the .avs file instead of the avi file
