Suggest me a camera. I want to buy a DSLR camera?

Hi this is chocolate…
I want to buy a DSLR camera for video purpose and Photography… Canon 600D, EOS 60D, EOS 70D, Nikon D5200, D5300…
Among these cameras which is Best for video…
Or suggest me other cameras… But budget is important…

You mention video as your most important requirement, that says to me that you will be disappointed with a DSLR's performance. Since taking "still" pictures is a DSLR's "forte"! I have always though that video on a DSLR is a sales promotion kinda thing. And then finding out that the sensors in DSLR's are different and don't last as long as the sensors in camcorders, meaning the DSLR sensors heat up and shut the camera down until the sensor cools down. So I would go slowly in this decision if I were you.

While the Canon 70D has to be the better camera overall, the Nikon D5300 has one videography advantage, it can record 1080 at 60 fps, which gives you a slo mo option.
