Please help with AutoGK <audio&fps>

[junglemike]

Hi everyone. I recently discovered AutoGK for myself and really satisfied with it's result. I made couple of DVD backups with superior quelity only on one cd.
But i have couple of minor problems when trying to convert video for palm. Would be very glad if somebody can help me.
Here's specs needed for palm:
320x200 (or smaller resolution)
usually half frame rate (11-12fps)
preferably mono audio (48kbps44khz mono or 24kbps 22khz mono or lower.
Movie has to fit in (usually 128mb sd-card) or 256mb.

I've done couple of encodes with with surprising results, 83mb result file (video only) 1.5 hours and still pretty acceptable qulaity.
But the I have 2 problems:

Problem 1:
since i cannot use lower than 64kbps audio i need to encode audio separately. So can i disable audio in AutoGK? And if not, how do i calculate a final size? Is there a way to know how much video part takes ?

Problem 2: Frame rate
Since i need in most cases half frame rate (11-12fps) and AutoGK does not have a way to change it, i need to open a result file in VD and choose "process every other frame" and then make a "direct stream copy". Is there any way to do it easier, like add something to the avs script before AutoGK starts to encode? Manono advised me to add SelectEven(), but i don't know where and when (at what stage) to add it? Will it affect filesize calculations?

I think the full Gordian Knot suits your needs better for what you want. The idea for AutoGK is to have an easy DVD to DivX/XviD transcoder without the need to tweak around a lot. If you want to do some tweaking, you want to use the full GKnot.

1) You can select any bitrate for the audio you want and GKnot takes into account the filesize calculation. In custom settings for audio you can make your mp3 mono.

2) I don't know if you can add things to the AVS script with AutoGK. I think you're not supposed to. With the full GKnot, it is easy to do. You want to put the SelectEven() as one of your first things in an AVS script (before cropping). I think there are other solutions as well. For example ChangeFPS (or something like that) or Decimate. But I'm not an expert on that. To go in depth on that, you would better ask on the AviSynth forum. It doesn't affect your filesize calculations as the AviSynth script is used before the compression (and calculation) takes place.

Thanks for the reply, i also think that regualr GKnot suits more for my purposes. But the problem is that GK doesn't work on my system. Every time i try to open d2v file (after DvdDecriptor and DVD2avi) i get this error:

I tried 2 different version of GordianKnot, tried 3 version of Dvd2Avdi ,(thought that it is it's fault), and 2 DvD disks. Also tried on another computer, reinstalling everything from scratch - no luck, Every time this damned error. Only AutoGK works without problem (on same computer with same disks.) That's why i'm trying to work around with AutoGK.

Are you using DGIndex to create your .d2v files? You should have it in your Gordian Knot folder.

[junglemike]

No, i can't find anything called "gdindex" in GK folder, or in GK itself. Where do i get it? Will it help me solving this error?
I treid to search for "gdindex" and did't find anything useful.
I just installed GK codec pack 1.7 and rip pack 0.32 - the last one To make sure i do everything right - still don't see any gdindex and same error.
Can you explain what is it? and whre to find it?

[piscator]

Note: DGINDEX not gdindex... It is in subdirectory 'DGMPGDec\DGindex.exe' in your GKnot install folder. If it's not there, you didn't install everything.

And I still find it easy to use robot4rip 0.5. It rips from DVD, prepares the D2V (also works with DGIndex), demuxes the subtitles and chapters. If you want to setup multiple projects, it still is a time-saver. The package 0.32beta doesn't include it anymore and the link in the Doom9 software section is outdated (0.4). If you want to use that, you have to get it from the 0.28.8 package or try to find it elsewhere on the web.

Thanks again. I want to try this Robor4rip. But do you know what do i write in lame settings so audio track will be 24kbps 22khz mono? In this window?

You can transcode the audio in robot4rip, but also in gknot after pressing 'save & encode'. see Doom9 Guide (http://www.doom9.org/index.html?/gknot-xvid.htm). I prefer to do it in GKnot, but it doesn't make much difference. Don't forget to add the '-m m' switch for mono.

Great thanks. It almost working. '-m m' is what i needed. Maybe you also know how do i choose sampling rate frequency? becaus when i put 24kbps it results in too low frequency (16khz) while i need 22khz.
I don't know why it chooses frequency automatically. I know there MUST be option for 24kbps 22khz mono, becaue i can see this option in lame settings in Vritual Dub. Do you know how to do this? Thanks
