it says "recommended fps 24" but the movie is 29.9! (hardsolving syncproblem)

[ChrioN]

I use smartripper to extract the vob's, then i convert the d2v to a fake avi using VFAPI Reader Codec.
I extracting the sound using Neo Sound Extraction (works damn good on other movies)
The last step is encoding in Virtual Dub. Here comes the problem, it says "the recommended fps 24fps", the movie is at 29.9 fps.
I encoded the movie in 24fps, then muxed the audio & video in nandub. BIG SYNC PROBLEMS!
Then I encoded the movie in 29.9 fps, STILL BIG SYNC PROBLEMS!
I dont get it! I´ve trying to manualy fix the syncproblem in Synchronizer but it doesnt get any better...i cant get the video to fit the audio or so to say!
I tried various fps, interleaving ms's and so on but the problem remains.
Please help!
FYI: Its a anime im trying to encode.

Enchanter is an expert on encoding anime's...PM him

oh dear!

I am sure Enchanter will read this thread

You should never ever use PM to discuss technical questions. It's much better to discuss these problems openly, where everyone can participate and benefit from the discussion.

I suspect that this is why enchanter has disabled PM.

[khp]

Of course my advice on the subject, would be to follow one of Doom9's Gordianknot guides.

[Enchanter]

I've never encountered Virtualdub complaining, "the recommended fps 24fps", the movie is at 29.9 fps." The program usually meekly accepts the pseudo-file.

Anyway, I'll ask the following questions. When you are creating the DVD2AVI project file, what is the reported framerate (by DVD2AVI in the Statistics Window)? If you're working on american NTSC disc, I'm sure you'll be seeing 29.97fps.

Next, assuming that it is NTSC 29.97 and that it is anime (which is almost always originally FILM material), you can use Inverse Telecine. Doom9 has done an excellent guide on this. The process will basically cut down the framerate down to 23.97 (Not 24.00, alright?) and remove interlacing artifacts.

After that, I'm sure you know how to create the DivX file of the anime show on your own. I'd like to know what format your sound stream is in and its bitrate and frequency. Be aware that you should not allow the frequency to go below 44.1kHz as this presents potential synch. problem.

Post back here for further guidance.

[ChrioN]

Its a NTSC disc (region 1), Trigun if you want to know and ofcourse it is 29.97fps. (not 29.9)
Im affraid I dont use dvd2avi, so I cant see the reported framerate :/

Im downloading gknot right now, very interresting guide there.
I'll try the Inverse Telecine but I think the deinterlancer in Virtual Dub worked damn good! well well...
the freq of the audio is 48khz.
I've also tried using the .wav file but without any progress...

By the way, whats pseudo?

- Big thanx from ChrioN.

How did you get the D2v file then ? from SmartRipper ?

This feature is very buggy in SmartRipper, and was only intended for PAL DVD's.

[ChrioN]

Yes, from smartripper, didn't know it was buggy though.
I'm right now encoding useing gknot, useing the doom9-guide...hope it works out fine.

[Enchanter]

I was going to ask the same question as khp. Oh well, you should use DVD2AVI to create the project file (.d2v). This is the basic of all frameserving methods.

Follow the guide from Doom9, on DIvX 3.11 Nandub. It is a very good guide, especially when it comes to NTSC materials.

I've done those things now.

I don't know if the final .avi is going to be 700mb as I (I think) choosed.
I'm encoding 2-pass with divx 3.11, the process has progressed 11% on first pass and the "projected file size" is 1154mb...is this normal? Or have I missed something?

[khp]

Yes this is perfectly normal. The first pass will be preformed at maximum quality, the second pass will create the real file.

[ChrioN]

I have now tried GKnot and followed Doom9's guide.
I can say that I'm VERY pleased with the results.
No synch probs and VERY crisp looking movies, it was a VERY big different in quality using Gknot from using "NeoDivx" automatical divx-encoding.
And on top of that, I REALLY get a 175mb file when type in 175.

Thanks Enchanter! /A very pleased ChrioN.

[Enchanter]

You're welcome. Glad I could help.
