I think I have found the problem. One of the AVIs giving me errors has a frame rate of 23.976fps (NTSC pulldown) and the other has one of 25fps (PAL) and I was using an fps of 29.97.

Am I able to convert PAL to NTSC simply by decreased the framerate or will I still get synch problems? If I do not lower the framerate of a PAL source to NTSC will the resulting KVCD play properly on my DVD player? I guess there's only one way to fine out, eh?

It would be nice if the FRC parameters were abstracted to a command-line parameter, eg. menkoder [base] [source] [quality] [source fr] where [source fr] is one of
  • NTSC = 23.976 fps
    NTSCFILM = 29.97 fps
    PAL = 25 fps

Check this first:
http://www.kvcd.net/forum/viewtopic.php?t=7771&start=62
and try to avoid changing frame rate, i.e. choose resulting frame rate equal to source frame rate, if possible.
(and if you change frame rate, you have to use FRC with telecine or filmdint parameters).

You try to use frame rate conversion from NTSC to NTSC pulldowned:
FRC="-fps 29.97 -ofps 23.976 -vf filmdint=fast=3,"
If it is a PAL source 25 fps, I would suggest to leave the result in PAL:
FRC="-vf "
or
FRC="-fps 25 -ofps 25 -vf "
Also, check audio sample rate; audio resampling can produce sound distortions.

Russianexpat, I testing this and this working full... i not have more problem with sound delay.

Code:
FRAMES=`tcprobe -d0 -H 10 -i $2 |grep frame.rate|awk '{print $4}'`
FRC="-vf " # fps not changed

if [ $FRAMES == 25.000 ]; then
        FRC="-fps 25 -ofps 25 -vf "
fi

if [ $FRAMES == 29.970 ]; then
        FRC="-fps 29.97 -ofps 29.97 -vf "
fi

if [ $FRAMES == 23.976 ]; then
        FRC="-fps 23.976 -ofps 23.976 -vf "
fi
but, i not like use tcprobe ... have another method to get FPS ?


Other question, have method to create chapters ?

thx my friend.

Hi and thanx for a great script.

There's something, however, I haven't really got:
I've got an avi that's 640x272 and I'd like menkoder to give me a 4:3 letterboxed SVCD.
From what I understand using the recomended ASPECT="2.35" will get me a full blown 4.3 image,
when mplaying the .mpg it seems to be that way at least.
I haven't burned the bin/cue (or even menkoded the whole movie) yet.

Have I got the above wrong or do I need to dribble with crop/expand (which I really don't understand fully in the first place) ?

Regards,
Peder

Your source aspect is 640/272=2.35 because for AVI files
view aspect is equal to pixels ratio.
(for mpeg files, on the other hand, aspect view is stored in a header and is not the same as pixel ratio).
Read these pages:
http://hkfanatic.com/widescreen/
http://www.uwasa.fi/~f76998/video/conversion/
and you have to do letterboxing or/and pan&scan
if you want to change aspect view to 4/3.

Well, I ended up using http://dvdripping-guid.berlios.de/en...ncoder-quantum with some modifications instead and that worked well
(except for some choppy audio, but that might have been my CDRW-disc. I'll try a CDR next and see what happens).

Edit: Nope, the choppy audio remains albeit to a lesser extent. Have to search the forums a bit methinks.

You have an older version of mplayer (0.92), you need the newer ones, like 1.0 or newer
