[MEncoder-users] Compressing the photo camera Canon A610 video to mpeg4 at the best quality.

[Strong]

I have photo camera Canon A610 that produces video movies (mplayer
says it is mjpeg) at 30 fps. Some second over 4 minutes of this video
takes 512Mb! I believe I can have *the very same* movie quality at less
capacity. So, as have tried not few the mencoder command line
combinations and was not satisfied with the quality, I give my
questions to those who are more expert with it.

My question is, What is the mencoder command line that will compress in
mpeg4 saving the same picture quality, visually?

Second question is, How to reduce the noise value the camera produces
at the least quality loosing?

Between quality/size choosing the choice must be given to quality.
