Some year ago (when transcode stable was 0.6-something), I had a
vobs-to-xvid-script with everything tuned to suit my DVD-player (which
plays Xvid-files on data-dvd). After a HD-crash I have reinstalled
transcode (from cvs), and am trying to produce the same nice
xvid-files that were produced before the crash. It works mostly well
(isn't it way faster now?!), but there is one big obstacle left which
I don't know how to deal with. I have tried with both xvid2 and xvid4,
with the same results. The avi is vertically stretched.
The commandlines are (they used to work with the old transcode stable):
transcode -c 0-00:01:00
-J extsub=2:0:0:0:1:255:0:1:1,normalize \
--export_prof dvd \
-M 3 -R1 -i vobdir/ -x vob,null \
-N 0x50 -b 128,0,0 \
-o /dev/null \
-y xvid2,null \
-w 1400,250,100
transcode -c 0-00:01:00
-J extsub=2:0:0:0:1:255:0:1:1,normalize \
--export_prof dvd \
-M 3 -R2 -i vobdir/ -x vob,vob \
-N 0x50 -b 128,0,0 \
-o preview.avi \
-y xvid2 \
-w 1400,250,100
The produced avifile becomes vertically stretched. Comparing a new,
streched file, and an old correct file, shows that there seems to be a
difference in import frame size: "720x576 [720x576] " has become
"720x768 [720x576] (*)". "--export_prof dvd" seems to be where the
difference is; if I remove it, the produced avi looks better (but
still a little stretched, maybe due to some aspect aspect):
tcprobe -i preview.avi

Here is tcprobe for an old file, produced by the same configuration
with the old transcode:
