The high iso clearity of the D700 is insanely good. If you can't put up the money for a D700 you could get the D300s.. it does video and would be the one step down from the D700. Its not full frame though.. but neither is the canon 7D.
If you go canon then do the 5D mark 2 or mark 3
Nikon is known for killing canon in their image quality.. but canon is exceptional on their video... probably because canon started putting video in their cameras sooner than nikon.
I prefer nikon for their quality and how quickly I can change settings without having to take my eye off the view finder.
Canon to me seems like a lighter cheaper build quality..
