Divx mpeg4 not accepted by TMPGEncoder

[agent222]

Recently I have had two .avi files that seem to have been encoded with Divix MPEG4 codecs. (as determined by video inspector.) They play fine through WMP, but when I try to covert (transcode) them, TMPGEncoder tells me that the files cannot be opened, or, are unsupported. I have the "enviromental settings" values at what is suggested by the "sticky" TMPGencoder problems.
But TMPGEncoder still won't take it. Anybody have an idea what's going on; how to solve this?

Kind of obvious, but check for MP3 VBR audio. Causes lots of problems with Divx to MPEG2 encodes. Try encoding just the video and no audio and you will know for sure if it's an audio problem.


Or the problem may be an unusual Divx file or format. I usually try to open them with VirtualDub and it tells me the problem. If you can open them with VD and everything is fine, use VD to frameserve to TMPGEnc encoder. That solves some problems.

Have you updated to the latest Divx Codec? I was unable to convert Divx in TMPegnc + until I did so, and now it works fine.

I'm again trying TMPGencoder to convert an .avi file that I've been having the troubles I mentoned in my orginal post. But before I put in the file into TMPG this time, I compressed it (recompressed?) using VirtualDub, compresing the video with the latest Divx codecs, and, setting the audio to MPEG3. So far, this seems to be working. (if others are interested, I found this solution at www.jhepple.com/support/divixvirtualdub.htm)

Recompressing causes quality loss, it's better to frameserve straight from Vdub to TMPGEnc. https://www.videohelp.com/virtualdubframeserve.htm

I'd seen that someone-was it you Zippy?, had recomemended installing the frameserver option (which I did in virtualdubmod,) but when I tried to find more information about this option by "googling", I didn't find anything. Since Zippy has linked me to a guide on frameserving,(which I've printed out for future reference,) it's obvious that I didn't phrase my search adequately, otherwise Google would've pointed me to it. In the meantime, we'll see how what I've done turns out.

Just so others will know, this is one of the frameserving guides from this site:https://www.videohelp.com/virtualdubframeserve.htm

It's not that hard to set up VD to do this, especially to encoders like TMPGEnc. Then you can edit, filter and do what you want with the video in VD, then send the results to your encoder without having to make a new file. Saves hard drive space and time.
