Xvid to avi issue with tmpgenc

[chris98007]

Hello all. I hope someone can help me. here is the issue.

I have an xvid avi file that i want to get to mpg. When i load it into tmpgenc the file is 3 times as big. I have read that i need to give a higher priority to the directshow filter. No problem, did that and it corrects the file length.

When i change that priority the setting goes from film to video and the end result is that the mpg is very jittery.

As i said the file is a xvid avi 23fps. I have tries reversing the field order and also selecting do not change fps.

What is the problem? It is driving me crazy!!!

It could be several issues. I would drop it into Virtual Dub Mod or the regular VD and check it for errors. You could also try a 'Fast Recompress' there and that may clean it up. I assume you have the Xvid codec installed. It sounds like more of a problem with the file than TMPGEnc.

Yeah i have put it through lots of different encoders. the problem is that the other encoders do a good job at everything except the audio is off! how do you check it for errors?

[redwudz]

The audio would be the first thing I would suspect. Especially MP3 VBR, but VD will tell you that. In VD Mod, just go to 'Video' and at the bottom of the list is 'Scan video stream for errors'

great i will check that out. By the way is there a good easy front end program to cce that will give me a mpg file? If i use cce by itself the picture is great but the audio is way off. I tried DIKO, but that does not have an option for mpg.

you can convert the audio with something else like ffmpeggui to mpa or ac3 and then multiplex/join the cce video with the audio using tmpgenc->mpeg tools.

why does cce make the audio out of sync? Will joining them in tmpgenc correct the issue?

[redwudz]

I don't think the audio problem is from CCE. I would follow Baldrick's advice. If you extract the audio with Virtual Dub or VD Mod as a WAV file (Using full audio processing) you can easily convert to AC3 stereo with ffmpeggui. Then can you select the AC3 and the encoded MPEG-2 and author to DVD. If you just want the MPEG with sound, mux the two back together.

But you need to find out why the audio is out of sync. VBR audio is the most common reason.
