3D Walk

Here's my 3D walk animation. Can anybody help me on the butt sway, I got so confused at which sides to go up or down and then the whole thing screwed up. x_x"

Also, I realized that my Fcheck program is different than the one Kaveh uses in that it doesn't have a "Save as Movie" option. It only has a "Save as Animation" option but it doesn't let me save as a MOV. It is definitely Maya 8.5 though. Crap, what will I do about my fruits... All 240 frames... Should I use Playblast instead I mean isn't that basically the same thing as rendering...? :[
