Hi there

I am not really a newbie per se, because I have done lots of my other stuff and it came out okay. But this is really annoying, so here i am, the first time I have ever posted anything. I'm having a little bit of trouble with converting something, and I don't know what I doing wrong, because the sound starts out fine but by the end winds up really badly out of sync. The original thing was made for TV, and it's rather long.

So here are my steps:

1) Rip with DVD Fab HD Decryptor

2) Process with DGI Index. I have tried with both "Honor pulldown flags" and "Forced Film," neither seem to have any effect.

3) Open the D2V file in GKnot. Go through the whole interlacing, compression check, et cetera. I am only using Audio1, and thing I use is "Just Mux." I am not sure how to work the interleaving thing.

The audio lasts 163 minutes 28 seconds, the video lasts 170 minutes 31 seconds.

I tried changing it in VirtualDubMod, by doing a Direct Stream Conversion, to have the audio match the video. No luck. And I've tried it, like, 5 times.

Totally lost here. Can anyone help?

Hi!

What is the Title and Region of your original DVD?

It looks like you're having a framerate issue. The numbers you're are exactly the numbers you'd get if you incorrectly flagged a PAL video as NTSC Film.

163.5 * (25/23.976) = 170.48

Make sure your framerate is 25. If you're using avisynth, a simple assumefps(25) should fix your problem.

Okay, I did a little bit of research (as opposed to my first instinct, which was to wring my hands and confess I had no idea) and dropped the assume FPS=25 AFTER the source. So now my AVI script looks like this:

# SOURCE
mpeg2source("G:\NEW DVD\FullDisc\veronica mars s1 d3\Veronica
v")
AssumeFPS(25)

I think I did it right, but I am not sure. (And I probably won't know for a few hours)

The DVD is Veronica Mars, Season 1 Disc 2 (Discs 1 and 3 reacted the same way. And yes, I know that I'm too old for the whole teenage girlpower thing but I can't help it.) It's actually region 1, so why this happened is anyone's guess.

Thanks - let me know if I messed it up and I will try to change the script. This is the first time I have edited the scripts by hand.
