First of all, I'd like to thank everyone who has contributed to the GKnot development. I've been using GKnot since 0.26 and each release has made the chore of ripping DVDs seem like less of a chore ;).

I have one problem with GKnot 0.28 though. Once I've started using 0.28 I've been coming across a weird problem... every d2v file I load into GKnot winds up at 23.976fps.

I'm using robot4rip to rip the DVDs and I can see that all of my DVDs are 29.97fps and over 95% when DVD2AVI runs. Whenever I manually bump up the FPS to 29.97 after I load the d2v I get a completed AVI file has an audio delay that increases as the movie progresses.

I'm encoding all my movies in DivX 5.

I must be doing something wrong and I haven't come across this particular problem in the forums :(

Thanks for any help guys

that's why r4r automatically turns "force film" on and you have 23,96 fps in d2v file...

Can I turn Force Film off in r4r so that I can get 29.97fps? I'd really like to keep my DivX files in NTSC instead of PAL.

Thanks

It *is* NTSC, just at 23.976. You may find this tutorial (http://www.doom9.org/ivtc-tut.htm) helpful.

Hi-

You don't want 29.97fps if it was originally film material. You want 23.976fps for a variety of reasons. But the best reason is because of the large quality improvement for the same file size that you'll get by encoding 20% fewer frames. Read the tutorial to which jggimi linked.

And as jggimi said, 23.976fps is NTSC. 25fps is PAL. So all this time you've been making your movies at 29.97fps? Now you have to go back and do them all over the right way. :)

Boy that's a long tutorial (whew)!

Thanks for all the help guys! I'm soooo pissed now that I have to re-encode everything again :angry:

Oh well... guess its better to do it right the second time than never at all right? I can't thank you guys enough for all this help. I guess I should stop everything right now and really try to *understand* what I'm doing before I do it.

Cheers:)
