Trouble converting AVI to MPEG/DVD

[gadgetguy]

Forgive my ignorance, but is there a reason why you're not adjusting the audio offset in Vdub?

gadgetguy-

Probably because I couldn't find the option to offset the audio before I converted it to a WAV file.

If you know how to do that in Virtualdub (or Virtualdubmod), and wouldn't mind letting me know, I would appreciate it.

Thanks.

Audio, Interleaving, skew correction.
Negative numbers will start audio before video, if needed.

Reboot-

Thanks for the info. I'll give that a try, as it will be one less app to use.

Like reboot said.

I might have missed something in this thread but try decompressing the Avi(audio)with the decompressor in avi2vcd,then open the new uncompressed AVI in Tmpgenc.
or
Install the handler included in the Vdub package and try frameserving the Avi to Tmpgenc.

reboot/gadgetguy-

I tried the settings, both +- 1152 ms offset, but the audio is still not in sync with the video. I'm trying AVI2VCD right now, so we'll see how that goes.

I don't know if you missed anything or not...I have an AVI file, with what appears to be compressed audio. I'm trying to get it into a format that I can play on a set top DVD player (that doesn't accept DIVX).

I downloaded AVI2VCD, and ran the AVI file that I have through the decompressor. The new file that it created, although larger, did play correctly in WMP. THe audio and video were in sync, just like in the original. I'm trying to create an MPEG via AVI2VCD right now, so we'll see what happens.

Thanks for your advice.

UPDATE:

I tried to create a MPG via AVI2VCD, but it didn't work. I got a fatal error that crashed the program. Here is the output from the log file:

I tried to run the decompressed AVI file through VSODivxToDVD, and it was able to create a MPEG file. When I played the file, the audio and video were out of sync.

I tried to run the decompressed AVI file through WinAVI as well. It created a MPEG file as well, but the audio and video were not in sync.

I tried to open the decompressed AVI file in TMPGenc. It said that the file was invalid, and would not process it.

I was going to try Mainconcept MPEG encoder, but I ran out of gas...maybe I'll give that a try tomorrow.

Don't give up on TmpgEnc just yet.
I used to use Vidomi to make xvids out of my television captures, for the most part it gave very good quality, but I could rarely get them to open in TmpgEnc even after decompressing the audio. What did work every time was frameserving.
Try this, install the handler in VDub if you haven't already and
Load your new avi,with the uncompressed audio in to VDub, start the frameserver and load the file you create in to Tmpgenc (I believe it's ***.vdr), it should open, otherwise I would say your Avi is flawed in some way,then check for missing/bad frames with VDub.
<edit>The only thing good about avi2vcd is the audio decompressor </edit>

[gadgetguy]

Make sure you set the Audio for full processing mode. You can make changes and test to see if it's in synch within VDub without having to process it first. Just make your changes, move to a good visual/audio synch spot and click the output play button.
Also make sure you are watching the output window, and not the input window.

Okay...I was able to get the handlers installed, and I was able to start the frameserver. I opened up the .vdr file in TMPGenc, but when I hit the start button, it told me that the file could not be opened, or was unsupported. If I click on settings>advanced>source range, it tells me that it cannot open the audio file.

If I tell TMPGenc to encode the video only, it looks like it will work, it just doesn't like the audio portion of the file.

gadgetguy-

Thanks for the directions. I set the audio in Virtualdub in full processing mode, and after I entered in the correct interleaving offset for the audio, I was able to get the audio/video back in sync in the output window. After I got this all set up, I started to frameserve the file, but then I ran into a snag when I tried to encode it with TMPGenc (see above post)

[gadgetguy]

Sorry, can't help you with TMPGenc. I don't use it enough to help further.

[propman07]

gadgetguy-

No problem. Thanks for your help.

[reboot]

Rarely will tmpgenc take a frameserved audio source.
Just save out the .wav from virtualdub, and encode only video in tmpgenc.
Adjust delay in your authoring app, now that you know how much to adjust it.
