I am new to linux so I need a simple guide that tells which software you're using for each step of the KVCD making process

I think the first step is rip the dvd with DVD::RIP- is this correct?

I have Mencoder but I don't really know how to use it yet. I think I need to use Russiansexpat's script but I want to start out with one process at a time in order to learn. Also what bitrate allocation method is used in mencoder and is file-prediction necessary?

Also what software do you use to burn the disc- gnome toaster?

Thanks,
ren

I don't have experience in ripping from DVD's with DVD::RIP, so I don't know anything about that. I have just encoded .avi files to kvcd.

I wonder who _really_ knows how to use it

This is a good way to start. Also dig into the scripts and inspect all the different mencoder settings, the settings are explained in man-page.

I don't understand that "bitrate allocation method", so I'll leave that for someone else to answer. What comes to file-prediction, do you mean final encoded size prediction? If so, I can tell russian's and el mozo's scripts have worked perfectly well, allowing the files to fit on an 80min CD, so I guess it's unnecessary.

Don't know about gnometoaster, but k3b (VERY GOOD!) if you want a gui. I do it from a shell, with cdrdao. (That part is also in most of the scripts, just configure them before use)

I think I've good choice of mencoder settings now, so
after another few tests on TV capture sources
I'll try to encapsulate the script settings in one of these:
http://gmencoder.sourceforge.net/
http://fixounet.free.fr/avidemux/
http://acidrip.thirtythreeandathird.net/

Would be awesome if avidemux could output k(s)vcd's!

by my knowledge that can be done already .

load movie -vprocess-vfilter(halfd1res)-ok-vcodec-svcd(configure codec-matrices choose kvcd - etc etc etc

the kvcd or ksvcd play on standalone player .

also double pass for size will give me an working kvcd or ksvcd .

so iam trying to detect best settings , i have made an kvcd with a gop setting 12 sharp as a knife , now i read that converting to an pal movie the gop size should be 25 .

anybody know the best settings or standard settings to create an ksvcd ,using the picture of tab (url) below ?



below the tab for cofiguring codecs into avidemux :

Group Of Pictires size is not most important parameter (structure of GOP - sequence of I,P,B frames more important though).
What is the most important (I've spent days and days on tesing my setiings) is how macroblocks processed, and how quatisation value (aka quality) and bitrate follows video texture.
So I was asking: is it possible my setiings - mbd, naq, masks, movement predictors in macroblocks, bitrate control functions and video filters - to put into some configuration file of avidemux?

The big trouble is that he seems to use lavcodec which produce slightly incorrect mpeg streams, not readable for example on my pioneer.

Hence the question about mbd etc.. which are libavcodec options

It is equivalent to XSVCD codec in avidemux2

From time to time i try to make it works better, but with little luck so far
(submitted a couple of bug and patch to ffmpeg's)
----------------------------------------------------------------------------
i ask mean the developer he give me this answer , if you want to have a better answer you have to contact "mean"

Nah.. I went to electronics store and tried xvcds and x(k)vcds with my setiings on 4 different brands and 6 models of standalones. All worked except one model failed to fast fwd/backward and another one was worked but picture was not good, but it was high bitrated xvcd without K-matrix and produced by mpeg2enc, not mencoder.
and all models worked with variable audio bitrate.
Pioneer was not among these models I have to admit though.
If mpeg pass through mplex and vcdimager, then it is most likely the problem of standalone model, because
vcdimager strictly follows vcd and svcd standards, and vcdimager pdf manual is the most comprehensive description of (s)vcd.

Any progress on this?

I'm learning Python, and took myself as a first Python (with wxPython) project to program a GUI for these kvcd-scripts. I'd post some screenshots, but I don't know where to upload any, since I don't have a homepage.

Hi tetra,

Doesn't your internet provider give you a small (~5MB or so) space
Almost every provider gives a small home page, with every account

I don't have an internet connection (anymore), I'm at a friend using his connection, so I don't have a homepage either. But I'll see what I can do.

I finally got around to installing k3b- you're right, it's great!

Now I want to encode some video to kvcd (mpeg-1). How do I execute a script with mencoder? Should I encode the audio seperately? How do I deinterlace the video? Is there a web-page that can explain the basic steps to encoding video with mencoder under Linux?

I'm a little closer- but still extremely lost.

Thanks,
ren

edit: nevermind, I finally found it
