How often do you have to modify the frame rate (or audio) for your DivX?

[Prizm]

Every movie I've DivXed lately has ended up with stretched audio, and I've had to modify the frame rate (using AviInfo) to get it right.

Is there something I'm stuffing up in Gordian Knot, or do I unwittingly keep choosing movies that have an audio problem??

I've been using DivX 5.02 and 5.05. The films have been PAL - E.T. (new version), Clockstoppers, Dumb and Dumber, and some TV MPGs.

The only thing changed in the way I DivX has been GordianKnot .27/.28. Previously I've had almost no problems when DivXing.

Anyone else have this problem, or is it just my bad luck with the films I choose?

How often do you guys have to modify the frame rate or stretch the audio when you do a DivX?

Never.

Are you sure you're taking the audio delay into account?

[majerle]

Never Too ( and PAL DVD, gordian 0.28 and up)

What program to transcode audio ?

Never

I haven't had to since I've stopped using SmartRipper well over a year ago. DVD Decryptor cured the audio problems right away.

[Awatef]

I always used SmartRipper and still use it, no problems at all

I use Vob2Audio to convert the audio to WAV. Anyone know a better program?

It's not audio delay I'm experiencing - the sync gets worse over time, which means it's stretched.

Maybe you guys never run into this problem because you're using NTSC DVDs? Perhaps the PAL conversions sometimes have hiccups?

I only ever rip PAL dvd's Prizm (living in Darwin) and I've never had this problem either. I use DVD Decrypter and dvd2avi to demux the ac3 audio, maybe it's vob2audio that's causing a problem.

[Prizm]

Yeah, I might have to see if it's Vob2Audio that's giving me these hassles...

Doesn't DVD2AVI only convert to AC3? Do you convert that into WAV afterwards, or do you keep the AC3 track?

AC3 is the audio format that is used on dvd's, vob2audio has to be decoding this to output wav.
You can use dvd2avi to decode the track as well, even downmix etc. but I get it to just demux the ac3 track which I transcode with oggmachine. For 2cd rips I usually just keep the ac3 audio.
I'm not sure how vob2audio handles it but dvd2avi includes the audio delay in the filename when it save the ac3 audio. This makes it easy to take into account and the tools written by DSPguru (eg. Besweet) automatically take it into account when transcoding.
It's sounds like the delay may be the cause of your problem, many movies don't have any and some are small enough that you wouldn't notice while watching the ripped version. If the delay is not taken into consideration it can cause the problem your having where the movie gets further and further out of sync.

when i run into sync problems i just extract the audio with xmpeg and then encode and mux with vdub, you'd have to mess around with the volume abit to get the loudness right but that's how i do it. gk is usually good with audio length when i use it though, so far i've only had to do that once.

[crusty]

I had to stretch the audio on about a dozen episode of the second Enterprise series to get them correct.
I was converting them from mpeg to xvid. Somehow the mpeg audio would not get properly demuxed with either Vdub or Vdubmod. Either that or there were framedrops by the TV-capture while the audio wasn't dropped.
I used WLA after founding Soundforge 5 to be not accurate enough. (LOL)
I preferred to adjust the audio because I wanted to keep the original NTSC framerate.

Never. I have encoded NTSC, PAL & Zone Free (Chinese NTSC) DVD's.
