here is a link to
MEncoder for Mac.
It can only be used from the command line, though. Search this forum and you will find a lot of examples how video conversion with mencoder for the M6 works.
Here is something for you to start from (posted by flyingbobo a while ago) :
Code:
mencoder Input.avi -idx -noodml -ofps 18 -vf scale=320:-2,expand=:240:::1,crop=320:240,rotate=1 -ovc lavc -ffourcc XVID -lavcopts vcodec=mpeg4:vbitrate=256:vmax_b_frames=0:vhq -sws 9 -srate 32000 -oac mp3lame -lameopts cbr:br=96:mode=0 -o Output.avi
Have fun !
