Over- and undersized XviD encode

[walruss]

Hi, got some problem with a DVD conversion to XviD. I have ripped DVDs to XviD for many years and used tons of different tools in my time and never had any problem like this. I use the latest StaxRip and every time it ends up over or undersized, can't seem to get it 1400MB like I want it to. It alwasys ends up ~1600MB+ or ~1200MB+.

I tryed StaxRip, MeGUI and maked a avisynth script and did it by hand using VirtualDubMod but no luck. Even tryed some old tolls like FairUse Wisard and Gordian Knot and still ended up over- & undersized. The only tool that did it right was AutoGK but I hate that tool. Tryed to demux the vide and audio stream, no luck. Tryed to mux it to mpeg, no luck. Getting a bit pissed off.

Any ideas what's wrong whit this DVD or what I can do to fix it?

It's only one particular DVD you're having trouble with? The other DVDs using the different programs, produce the sizes you want?

The only tool that did it right was AutoGK but I hate that tool.

That seems an odd thing to say about a program that gave you what you asked for.

Anyway, I'd suggest removing your XviD codec using Add/Remove Programs and then installing it again. Sometimes installing one on top of the previous version results in the problem you're having.

Yeah just this one DVD, as I said this has never happend before. No, It always ends up over or undersized with -200mb or +200mb with all other tools I tryed.

Well AutoGK does't have the options that I need and it ends up a bad rip, as I follow "specific rules".

Anyway, that didn't work. Tryed to rip it on two computers but still the same result. A friend tryed on his computer and same thing there. Seems to me somthings wrong with the DVD.

Does the DVD have multiple versions of the same movie, such as theatrical version and a director's cut or extended version? If so it could be a problem specific to this DVD and how you ripped it.

No its just a simple DVD with just the movie and no extras. Even tryed to convert to x264 mkv and then rip to xvid and the same thing happend.

I've never had a problem like this so I can't speculate too much.

However can there be a variable bit rate audio track in the mix here? Is that possible on a normal dvd? Assuming this is a completely normal dvd as the original poster is stating?

I know I've read about problems with vbr audio on many many posts in the past. I don't know if that is even possible in this scenario.

You could try demuxing the video into a m2v and ac3 file. Then convert the m2v to xvid or x264 separately and remux with the original audio later. Couldn't hurt to try.

Again I don't know if vbr audio is relevant in a properly authored dvd or not but thought I'd throw it out there anyway.

Yeah it's a normal DVD. I tryed everything like that, demux and encode video and audio separate and mux but same there. Can't get the DVD to encode at any specific size that I want.

You still haven't shown to us the exact Xvid settings that you've been using.

Don't think it has anything to do with the xvid settings, same thing happens with x264 codec as well. Tryed different settings, same thing.

Avisynth script I used:

LoadPlugin("G:\DGMPGDec\DGDecode.dll")
LoadCPlugin("G:\AviSynth plugins\Yadif\yadif.dll")
MPEG2Source("G:\DVDR\VTS_01_1.d2v")
Crop(0,0, -Width % 8,-Height % 8)
ConvertToYV12()
Yadif()

If it was just Xvid I'd suggest using a different version. Some versions were/are broken when it comes to achieving a target file size. I can't remember why exactly (it's been quite a while since I've encoded with Xvid). I think it was something to do with the way the overflow settings worked, but the Xvid version would be a common denominator (most likely aside from AutoGK) if it wasn't for the fact you say the same thing happens when encoding with x264. That has me stumped.

Have you tried encoding with just the default Xvid/X264 settings to see if it's something you're doing there causing the problem?

[walruss]

Yes I have tryed that, and as I said it's the same problem on all computers I got at home and even when a friend tryed on his computer. Tryed changing xvid version to an older one but still same shit..
