Great, now, which values should I pass to the crop parameter, the ones that are 
constant to the rest of the movie?

I'm using -scale 640:480, for a movie of an 1 hour an half and a bitrate of 
1900, and the vcodec:mpg4 vhq vqlim, vlelim, dark_mask and lumi_mask parameters 
that appear in the encoding-tips.txt that comes with the documentation.

Thanx for your time.
