The Sony a6300 is a small mirrorless camera that just blew my mind with it's autofocus. It is stupid fast and the camera features a AF-C or autofocus continuous, meaning while you are recording your videos, the camera will stay on point.
If you are getting started with video and are partial to Canon, this is a great starter camera, Articulating screen means if you are shooting overhead you can still setup your shots seeing what the camera sees.
I am biased because I own and love this camera. Full Frame mirrorless which takes wonderful pictures but really shines with all of its video features. If you are looking for more advanced features but don't want to break the bank, this guy is good.
The newer version of the a7 but with some new features.
