Use svcd/2 pass for best results, you also set your output size,although
it tends to run a hair "large".
avidemux-2.0.22 (possibly earlier) can also dump mpegPS aka vobs, as
well as load mythtv nuvs directly, (mpeg4 OR rtjpeg) then import into
vobcopy and dump to iso with an "i" keypress.

>I've been using nuvexport to transcode my 480x480 RTjpeg recordings to
SVCD. It's worked well. Now I have an M-179, and want to make an
SVCD. My recording profile is set to 480x480, and I've already used
avidemux2 to cut the commercials (on keyframe boundaries). Now I need
to turn down the bitrate to something in the SVCD range. The question
is, exactly how do I do this in avidemux2? I looked at the Video Codec
options, and there was an SVCD preset. However, I have to choose
between setting the bitrate or setting the quantization. Which do I
want? Is one faster, or will one give better results?
Hopefully I'll only need to do this on a few recordings, as I'm changing
my profile to record at 1/2 D1 so I can burn CVDs instead of SVCDs.
TIA,
JAC
