I was trying to encode sections of a *.vob file to avi
using mencoder. The source of the vob file is a NTSC
region 1 dvd. It was transferred to the hard drive
using vobcopy. The main movie was then stored as a
single vob file using the "cat" command.
Here an example of the command I used to make an avi
mencoder movie.vob -ovc lavc -lavcopts
scale=640:480,lavcdeint -oac mp3lame -lameopts
abr:br=128 -o movie-part2.avi -ss 00:51:40 -endpos
(I did the same command with vpass=2 for the final avi
It works great except the timing I enter after -ss
doesn't agree with the actual timing. The discrepancy
increases the further into the movie you go. The
-endpos timing seems to work (it encodes 45 min). I
worked around it by trial and error guessing -ss
timing and encoding a few seconds to see where I
actualy was. Any ideas on how to correct this?
