I've got a case of the jitters!

[MetaPhaze]

Hello again,

I've been trying to take 5 Xvids and basically burn them on DVD. The problem I have right now is joining the Xvid files together.

I've used AviMuxGUI and it handles videos 1, 2, and 5 just fine. However 3, and 4 are all "jittery" is the best way I can explain it.

Now I've tried using Vdub and VdubMod and both tell me that the Audio formats differ?

Well as a last gasp of air I tried using TMPGenc to encode each of the AVI's seperetely in to MPEG2 (DVD Format) however when I do this it tells me each of the (350MB) Xvid files are going to take up like 8gigs, and the total playtime of each Xvid is a 177 minutes when in reality the playtime is 45-47 minutes long.

Any help would be appreciated!

I spent 12hrs encoding these video files with Avi2DVD only to find out when I got on to video files 3-4 that they were all jittery after burning the DVD.

I can think of several possibilities. First of all check the Xvids with Gspot. I suspect MP3 VBR audio or possibly AC3. That can cause TMPGEnc to come up with huge filesizes. You can extract the audio with VirtualDub Mod. (Though VDM would have told you about VBR if you had dropped them in there. ) How does the audio differ with those two problem Xvids?

A guide here for audio extraction with VDM:

Jittery might be wrong field order, not an expert there, but others can tell you more. A forum search for 'wrong field order' might help here.

And I would convert them to MPEG-2 and let your authoring program combine them. A lot less chance of sync errors that way.

Think I would try (probably with v/dub/mod) demuxing a small portion of the prob. vid, making sure it played OK, that there was no *jittering*, then try encoding that & checking the results. Think as redwudz said it jittering might be prob. with field order, or possibly fps, or encoder not reading the file correctly, &/or probably others I haven't thought of...

At any rate using a small test file will give you results one way or anyother fairly quickly.
