              Stop encoding at the given time or byte position.
              NOTE: Byte position will not be accurate, as it can  only  stop
              at a frame boundary.

              EXAMPLE:
                 -endpos 56
                      Encode only 56 seconds.
                 -endpos 01:10:00
                      Encode only 1 hour 10 minutes.
                 -endpos 100mb
                      Encode only 100 MBytes.

First approach, if you mean with mencoder, does not work.

$ mencoder -v -sb 409993216 video1.wmv -ovc copy -oac copy -mc 0 -noskip -o video2.wmv
