Re: [vox-tech] mencoder - slower and scaled?

I sympathize with you, Bill.  Getting the frame speed right is a pain in
the rear (especially if you got sound and need to video to it *and* get
the frame speed correct.)

As I recall, mencoder has an option for setting the input frame speed and
the output frame speed.  Try setting those.  Also look into "3:2 Pulldown"
option for converting 24.9fps to 30fps (which you may or may not need.)

Good luck!
