The OP was using norm=PAL so this frame-rate is not useful for him.

Any reason you are using mjpeg? It typically should lead to huge files and/or
worse quality than mpeg4 ...
(Does vbitrate really work with mjpeg? I don't know.)

This is almost never correct: In my case (PAL), the input is either progressive
(then lb hurts quality) or interlaced (then yadif is always better), I suspect
in your case, it might be telecined, in which case better filters exist afaik.
