Should i buy a MIRRORLESS or DSLR for shooting VIDEO? (My first camera)

[ruanitto]

Hi everyone!

I saved some pennies and i'm ready to buy my first camera. I'm a Graphic Designer and Film and TV student and would like a camera to get photos for professional use, as well as short independent films. I'm looking forward to buy an entry-level camera to get started, and reading in lots and lots of websites i came up with some options, and would like to have some professional advice to the final decision. My budget is around AU$500-750.


DSLRS:
Nikon D3300
Canon EOS600D
Canon EOS 60D


MIRRORLESS
Sony Alpha A5000
Sony Alpha A6000
Samsung NX300


Which one of the above would be my best option for take excellent quality PHOTO and VIDEO, considering AutoFocus for video (i don't get the concept very well)?
Still on video, a Mirrorless would really fit better than a DSLR? If yes, can i still get some "DSLR-level" photographies with it?

Thank very much for your help!!
