Sony A57 grading your video footage?

I'm looking for a dslr under $700 for mostly video work but also photographing animals and movement. I know the GH2 is best but I want a larger sensor. Is there a good flat setting on the Sony A57 so you can grade your footage? I'm trying to pick between a Canon T3i and A57.
Maybe someone would be kind enough to shoot a clip for me with flat settings on their A57 so I can test out how well it handles grading?

thanks
