I modified russiansexpat's script (borrowing something from paranouei's script too) to fix the aspect-ratio problem automatically. I fixed it like this:

Code:
scaleto=TARGET_HEIGHT-(480-MOVIE_HEIGHT)
for example a PAL SVCD where target resolution is 480x576. I encode a movie with original resolution of 640x360

Code:
scaleto=576-(480-360)
This seems to work, checked with Universal Studio's movie 2Slow2Calm, where the earthglobe comes, which is round with this script, with original russiansexpat's script the earthglobe looks like an egg.

Also, with this script you can encode subtitles. Might be good that you check the subpos variable after encoding a short sampleclip.

[EDIT]
Forgot to mention, that this script cannot handle subtitles, if encoded directly from a DVD.

Here's the script.

Thanks.

Just a few minor suggestions:

scaleto=`echo "$HEI-(480-${HEIGHT})" | bc -l`
scaleto=`echo "$HEI-($WID-${HEIGHT})" | bc -l`

Use http://mpgtx.sourceforge.net/
to get information from mpg source (tcprobe does not work with them).

VFILTER="hqdn3d,"
VFILTER="denoise3d," I could not mention any difference between quality but denoise3d is faster.

Bring back $SWS variable to choose type of software scaler
-sws 2 should be if you do upscaling either dimension.
Video filter time consumption is minor compared time spent by vcodec.

I did not try keyint=$OTHER gop sizes, but I saw ppl use 50.

Finally, if you use tcprobe or mpgtx to detect source resoluition and fps, and do calculations and scaling,
you can have static code with no need of editable section.

If you have toolame from http://mikecheng.d2.net.au/#tooLAME you can try to encode sound with variable mp2. Not sure if standalone players are capable of playing variable mp2.

Ooops, whipped that up too fast to think like that

I leave that for you

Great, gonna try that.

I don't have the slightest idea what that does or means.

That is very true.

I'll leave this one for you too

Did you try CQ mode instead of just VBR. I added this vqscale=5 to my script and the compression gained a lot(also I removed the VBITRATE).

2) I missed here something. My understanding is that quantisation matrix tells encoder how maintain quality in proximity of enconding frame and if bitrate is variable, encoder adjusts it accordingly.
Constant quality encoding is maintaining target quality and to adjust bitrate accordingly.
How you can mix these two different approaches - constant quality (CQ) and Matrix?

1) I have some doubts how mencoder actually processing the matrix. mencoder mpeg1video and mpeg2video codecs are based on libavcodec from ffmpeg. I can't see options in command line ffmpeg for custom intra and non-intra matrices;
then how mencoder can have them?

Constant quality and a matrix are two different things, but related

I use ffmpeg-0.4.8
I saw some scetches that next versions of ffmpeg have it, but
on this machine I can install .rpm only without compilation.

Below is a version of the script with constant quality.
It appears to be faster and easy to use, just watch output line of mencoder - last field of this line is a current encoding bitrate, and also in this line you can see estimated time of completion and file size, so you can terminate the script if you don't like them.
(some minor problem with maxrate - when you select high quality, the maxrate is exceeded; nevertheless tcmplex clipped bitrates to 2300 max and vcdimager didn't complain.)
Code:
#!/bin/bash

# Copyright (C) 2003-2038 russiansexpat

#
# requires:     mencoder mplayer ffmpeg tcmplex vcdimager cdrdao
#
# does not require: microsoft. This script has not been tested on animals.
