[ILUG] [May be OT, May not] Video recoding/transcoding

[Justin Mason]

Your best bet may be to ditch that MSware and get down and dirty with free
software and a command line ;)

e.g.:

  mencoder -oac mp3lame -lameopts cbr:br=64:vol=2 -srate 22050 \
      -ovc xvid -sws 1 -xvidencopts bitrate=150:max_key_interval=120:vhq=3 \
      -ofps 15 -vop scale=500:372 big.avi -o small.avi

that's a command line I used recently to transcode a large AVI file down to a
lower bitrate and size; mencoder is your best bet.

through conscientious man-page reading, and trial and error, you can probably
get something similar going for MPEG transcoding, to bring them down to
the compression, bit rate and size required for DVD MPEGs.   iirc, the
MPEG format used on DVDs is pretty simple and well-supported.
