Examples of DVD to xvid4

Widescreen NTSC

export COUNT=$1 export IN=/input_dir/VTS_01_$COUNT.VOB export OUT=/output_dir/VTS_01_$COUNT.avi

The reason to use a separate work directory here is that xvid4 creates a file called "divx4.log" in the current working directory, so otherwise it would become overwritten if multiple instances of this script were to run:

cd /work_dir/$COUNT export RESIZE="-B 12,10,8" bitrate 1500. export BITRATE="-w 1500,250,100" If you see thin horizontal lines on fast motion, you need to deinterlace: export DEINTERLACE="-I 3" If you want to keep the original AC3 soundtrack rather than encode it to mp3, e.g. if you are using an external "receiver", use this: export AC3PASSTHRU="-A -N 0x2000" Invoke transcode. Use "-M 2" to keep audio in sync. First pass: transcode -i $IN -M 2 $BITRATE $DEINTERLACE -a 0 -b 128,0,0 $AC3PASSTHRU -V -f 25 $RESIZE -R 1 -x vob,null -o /dev/null -y xvid4 Second pass: transcode -i $IN -M 2 $BITRATE $DEINTERLACE -a 0 -b 128,0,0 $AC3PASSTHRU -V -f 25 $RESIZE -R 2 -x vob -o $OUT -y xvid4
