XVID Conversion Problem using VirtualDub and TMPGEnc

[mjohnson]

I am converting an XVID Avi using virtual dub back to a standard AVI (Direct Stream Video and Full Processing no compression Audio).

I then pull this into TMPGEnc for conversion to MPEG1 for VCD.

I am getting mixed results. Sometimes the process will get to 99% and then give an error with kernal32.dll and sometimes I get an error "Invalid index at 272" right at the beginning.

I have successfully done DivX conversion using this method and this is my first XVid attempt.

I am running Win98, VirtualDub 1.4.9, TMPGEnc, with XviD-04102002-1 Codecs.

Any advice appreciated.

Try increasing the directshow priority in tmpgenc

Hi Rambo78,

I tried modifying the DirectShow property to 3 and this now seems to allow me to work directly from the XVID AVI!

Am I going crazy here, but I didn't think that was possible in TMPGenc.

It has only just started and appears to be going well!

Any explanation for this?

I have a first question, how can it be that more and more files are stored as XVID when it seems like it is causing a lot of problems?

I have similar problems. Firstly I cannot get TMPGenc to start using an XVID file and now it is also causing problems with Divx, after having downloaded AC3 codec. When I try with Divx I get a lot of pop-up messages with error numbers. I'm gettin desperate so pleeeease help

[Rambo78]

Your not going crazy.
It is possible to work with a xvid directly.
But you should still extract the audio with virtual dub first.
The reason you have to increase the directshow priority is because
certain files are associated with different plugins and sometimes you have to increase these prioritys so that the right plugin is used

This is how I convert Xvids....

First I decompress the avi file using the avi audio decompressor bundled with AVI2VCD.

Then I can encode it with TMPGEnc with no A/V sync problems.

Short questions is this the one that creates the file with the extension PCM and do you then use this for audio alone or also as input file for video?

[mjohnson]

Oh well - all seemed well and then at 99% it completely locked up the machine!!!!

Rambo78, you mentioned about extracting the audio using virtual dub. In which way do you mean (to save as a WAV???).

I currently load in the XVID AVI and set Direct Stream Video and Full Processing Audio with no Compression and leave it set as AVI Audio. I then select SaveAs AVI.

Thats the way I normally do it with DivX AVI's and it seems to work fine!

I'm getting really frustrated with this now, which makes me even more determined to find a solution.

I may well give TeleMike's suggestion ago.

It wouldn't be so bad if it wasn't a 2hour conversion process upto 99%!

Thanks again everyone for your input on this one!

Try this..... alternitive way: check for bad frames with Vdub mp3, extract audio with regular Virtualdub, then..... convert it with Panasonic MPEG1 encoder. This ALWAYS work. If its a Xvid with Ac3? Then use Cillers Ac3-tool. Get it here:http://www.digital-digest.com/dvd/downloads/ac3tool.html

Right now.....I'm making a guide to convert Xvids & Ac3 to VCD using Panasonic & Cillers Ac3-tool. Let me know if it worked for you, ok?

I mean extract the audio using full processing mode, no compression
save wav.
By the way have you scanned your avi for bad frames??

[mjohnson]

I tried TeleMikes route and still it dies at 99%.

I must admit I haven't scanned the AVI's so I'll give that a go.

I'll scan the AVi's, then try the full WAV extract as suggested by Rambo78 before I give Dutch Coders method a go.

Thanks again and I'll keep you posted.

[telemike]

The AVI decompressor adds " _PCM " onto the avi filename. I use that for the audio source in tmpgenc.

[mjohnson]

Still No Joy!

I ran the scan on VDub and it reported no bad frames.

I ran GSpot which told me I had all the correct Codecs installed to handle the files.

I extracted the Audio to a WAV file and tried the conversion with that and it still bombed out at 99%.

FYI I have tried this on 2 PC's so it's not a machine fault (more likely user ).

I'm going to give Dutch Coders method ago, off the top of my head I don't think its running with AC3 audio but I'll have a go anyway.

Thanks again.

mj, I had a kernel32 problem about 6 months ago. I would get the error on 2 or 3 movies. I read and read and read and tried and tried. I won't go into detail all of the things I did. Suffice it to say as a last resort I reformatted my hdd. Nothing worked. I eventually redownloaded the movies and that did the trick. I now believe that the movie files were corrupt. Good luck.

Hey MJ, I believe i had this problem a while ago.

when u scan for errors on the avi make sure you use Vdub-mp3 freeze version.
It scans for freezes and will find errors that normal Vdub will not find...then u simply delete the bad frames and resave out the avi. This solved my problem and tmpgenc ran smoothly.

[rickki804]

Ok.. I have searched and found 1 bad frame. How do I get rid of it????More importantly, how do I find out exactly where it is. V-Dub didn't say where it was.

[Scrow]

Hey, there is a guide on this website for bad frames....I suggest u read it.

Vdub mp3freeze version will make a log (C:\badframes.txt)
and it will show all the bad frames.

Find the guide to bad frames on this website and it will explain how to delete it properly

I've found I get that error message at 99% if the audio is shorter than the video. It doesn't seem to care if its only shorter by a few ms, but when you get into seconds or even minutes, then problems will arise

Check that the A and V are identical length.
