Why not VFAPI?

I've been basically using the method presented in the guide, "Copy your DVD into DivX5 format - Guide for 16:9 anamorphic movies", with a few modifications to provide support for DivX 5.2 Pro, Dolby Digital AC3 using VirtualDubMod, and DivX's new built in bitrate calculator, along with its own crop and resize filters. For some reason, the movie I'm currently working on has a problem with either DVD2AVI or VFAPI. About a quarter of the way into the movie, a strange phenomenon occurs for about 15 seconds where any moving objects have vertical lines and seem to skip a bit. It is very similar to what happens when you watch a VFAPI .avi file on a slower computer. This problem appears on the fully encoded file as well as on the VFAPI file. I spent about an hour looking for an answer, during which I came across a few threads stating something about how VFAPI wasn't supposed to be used anymore(??).

vfapiconverter is considered forbidden like the past 2 years....?

Do not use VFAPICodec anymore.
Could somebody please explain to me why VFAPI isn't used anymore...and perhaps what I can use in it's stead for getting video data from the vob files to VirtualDub?
Any help in this matter will be greatly appreciated.

did i post that quote ?
one thing i know is that vfapi is slow. in a more technical disadvantages or flaw, i'm not to sure about it, so i won't spread any false information until. at least until i conform what i know. :)
yes the alternative is the powerful frameserver, avisynth.
http://www.avisynth.org/
some guide thats good for newbies.
http://www.animemusicvideos.org/guides/avtech/
its more than a frameserver, it can filter out noise, anything that can be done with a video editor.
but with scripting language, but easily learn.
if you're too lazy, just use vdubmod as you're now ;)
and the guide you mention is 2 years old since last updated *shakes head*

Thanks shiroh. I'll check out Avisynth.

You'd have to admit it was a good guide 2 years ago when I first started to learn. Since then it's held up pretty well, with a few modifications.
SmartRipper to DVDDecrypter, 2-pass to 3-pass, MP3 to AC3, the application of Subtitles...
Actually, maybe it's time somebody updated it.
But I'm glad I finally found a way to work around VFAPI without using TMPGEnc or some other Encoding App.
Thanks a ton, shiroh.

MP3 to AC3
I don't understand... ?
AC3 soundtracks come off DVDs (using SmartRipper to demux).
It is a nice, pre-compressed multichannel audio file.
They certainly don't come from MP3s, in fact most make AC3 files into MP3s, don't they?

When I listed those things, I was listing the deviations I had made from the original guide shiroh and I were referring to, not the steps I went through to rip and encode the dvd.
I don't think anybody goes from MP3 to AC3, as it would be pointless, since the whole purpose of AC3 is to hold more than two channels while still applying the extremely useful compression that has made MP3 famous. I was simly saying that while I used to convert the original AC3 to MP3, now I leave it in AC3 format, hence the shift of the end product being from MP3 to AC3.
But it's nice to know that you're always there to proofread my material, OGS ;)

mp3 to AC3 only happens when ou want it on dvds
try AC3 to AAC. normal dvds will use 448kbps for its 5.1 channel audio. you can go half that size on AAC with 5.1 channel.

I am encoding videos for use my a 5.1 surround system along with an HD projector, so I prefer not to mess around with the quality of the audio simply to drop the size a hundred megs. AC3 is a fine format, crystal clear, and it isn't worth the time and effort if the end product will basically be the same thing. With the assistance of AC3Filter, it's much easier to leave it alone. But much thanks shiroh!
