I love my Sony a6000, but it is not a great video camera. 15-20 minutes max. Overheating is a major issue. I do not know if it has been resolved either in the 6300 or 6500. That said, it runs circles around my DSLR's for stills.
The newer Sony cameras do overheat less. However, there is still that annoying 29m59s time limit... due to a tariff. Sony's full frame A7s II is the low light video champ. No doubt, they will make more and more capable hybrid cameras.
The Panasonic Lumix GH4 and GH5 do not overheat, and do not have the half hour recording time limit in the USA. The GH5 has no time limit, anywhere. They are engineered from the ground up to be *both* stills and video cameras. There is an excellent balance of the two capabilities. The menus are incredibly well laid out. The controls are in the right places. You can customize the buttons and dials on the cameras in a wide range of ways to suit your habits. The feature lists go on and on.
The GH4 was ground-breaking. It was the first stills camera that many serious filmmakers and video pros respected as worthy of at least B-roll work. The GH5 extends that by an order of magnitude. I've had a GH4 for a while, now, and I'm still finding cool features I hadn't noticed before. I use it for stills and video, and sometimes I extract stills from the video.
Panasonic has been smart about updating their cameras, too. The GH4 went through two major firmware upgrades and many minor ones. Most of the upgrades added features, in addition to fixing bugs. Mine is fully updated to version 2.6. When Panasonic announced the GH5, they also pre-announced several firmware updates. They were waiting for media manufacturers to make faster SD cards to support some of those features! So the camera you buy gets better and better. All the updates are free. There is a firmware upGRADE to add V-Log-L video capability, and that costs $100. It's for very advanced users who need maximum dynamic range for filmmaking. There's another update or upgrade coming which will add anamorphic capability.
The inherent problems with most dSLR cameras that record video include overheating during video recording, poor AF performance for video, lack of a real viewfinder for video, cheap, noisy microphone pre-amps with automatic gain control that cannot be turned off, lack of a headphone jack for audio monitoring, high crop factors when recording video, inability to control picture parameters in ways video professionals are used to, lack of overexposure zebras and focus peaking, and more. Panasonic has eliminated or at least addressed all those concerns and limitations. They are listening to the professional "hybridographer," cinematographer, and pro videographer communities in a way only Sony can (or will) compete with.
Canon and Nikon have so much invested in dSLR "market inertia," they have to protect it. They are afraid to kill the cash cows that keep them alive. Those cash cows are dSLRs and lenses. About 80% of stills photographers use their dSLR systems, so there are tons of Canon and Nikon lenses in circulation. Canikon want to keep it that way, so they have paid lip service to mirrorless camera technologies. Canon, of course, makes pro video gear. They want to protect that market, as well. On the other hand, Sony and Panasonic have chosen a different path...
Canikon will probably not release seriously better mirrorless/hybrid camera designs any time soon. They don't have to, yet. But I hope for their sake, they don't wait too late. We need them in the market.
I used Canons and Nikons from 1968 to 2012, and have enormous respect for what they have achieved. However, my needs took me in a different direction. I got tired of traveling with several cases of gear, just so I could record stills and video of the same things, separately. I needed to streamline my workflow, too. The GH4 has done that for me.
