> First of all thanks. I am using PAL standard. My movie has PAL resolution, if I cut it down to less pixels and then add black pixels that means I lose on resolution, don't I? Isn't there any other way? What command do you use to do this rescaling (for NTSC)?
You lose on resolution but you gain on effective bits

stuff that you can never see.
This filter chain is the one for NTSC video:
You can use it with mplayer to see what it does.
