avimerge - video faster than audio

[mousemurder]

hi, i got 6 unencrypted vob's from a dvd i own and i noticed this on a few dvd's i want to put on my portable media player.

i did this command on the vob's so now i got 6 xvid-avi's:
then i use avimerge to assemble the 6 avi's together...


[mousemurder@doom9 vob]$ transcode -y xvid,xvid -F mpeg4 -M 2 -N 0x55 -s 3 -w 750,75,90 -b 64 -B 12,10,8 -i VTS_01_3.VOB -o VTS_01_3.VOB.avi

notice that the first vob has a framerate of 29.970 and all the rest of them have a framerate of 23.976 (is this some sort of counter-reproduction measure ?)

is there some way to make it so that the first vob is transcoded with the framerate as the others ?

thanks,

Hi!

You can likely overcome your problem by initially creating ONE .AVI from your DVD (rather than 6 .AVIs)...

good idea, but my transcode keeps crashing at around 65% thru the moo-vee.

any other ideas...

Join the 6 video clips into 1 big AVI. Then join the 6 sound clips into 1 big soundtrack (if possible, transcode the big soundtrack in one go). Finally mux the big AVI and big soundtrack together.

thanks, i didnt explain the problem well... when i did avimerge, after about 20 mins into the moo-vee (after vob-1 is transcoded) the avi would go about 1.5 speed with the audio at normal speed.
...
the VTS_01_3.VOB file was bad. i re-ripped it, put them all in a directory then did transcode -y xvid,xvid -F mpeg4 -M 2 -N 0x55 -s 3 -w 750,75,90 -b 64 -B 12,10,8 -i vob -o moo-vee.avi
not sure why vobcopy originally copied the vob wrong (must've been some dust on the disk).

thnaks,
