Canon t3i (600d) or Nikon d3200 for video?

I'm interesting in buying one of those 2 dslr's. I'm curious which one is better for video, and why

Neither. Look at Sony if you want to shoot video with a DSLR. If you really want to shoot video, you would be better off with a camcorder unless you need depth of field control.

Qrk is right. The Sony A-58 will blow a true DSLR out of the water for video, but it's a poor substitute for a camcorder.

You'd have to be Really stupid to consider a stills camera for video, and not look at Sony.

Neither. Buy a Camcorder or Video Camera, not a stills camera.

Canon

If you want to stay in these options then i would suggest the Canon T3i. Canon has better video making than Nikon
