Overheating during video

Go try 30 minutes with your nex and see what happens. It probably won't shut down, but the quality will be substantially degraded as the time goes by, if you're shooting over 800 iso. Heat doesn't work well with these high megapixel sensors w eave nowadays.

I may try it and see, but I know it has already been tried and proven to work. Sony A6000 Review - Shooter's Report Part III

I also know there are other sub $1000 cameras that can go much longer - the Panasonic GH3 is reportedly unlimited. I don't know what $1000+ cameras you are using that have such severe limits to recording time.
 
OK just to make sure I had the details correct, I went back and looked: between 10:29 am and 11:05am I took videos of 0:31, 4:17, 3:48, 0:45, 0:23, and 4:56. So 14 minutes and 40 sec over the course of 36 minutes.

Please re-read what I said, as I didn't say it wouldn't work at all.

Video capture, especially at HD or higher resolution, causes a lot of heat from the sensor and the processor. With a standalone camera, they are made to be more efficient, and can handle the stress better. But not completely.

I primarily shoot Olympus and Nikon now, but have used lots of others over the years. Olympus specifically hasn't done 4k with their cameras because of the strain it puts on them, especially due to their optical stabilization. Your panasonic gh3 doesn't have stabilization, and Panny is a world leader in video. But even their new gx8 camera, which has optical stabilization, disables the in body stabilization during video because of it.

My point is this: HD or higher video capture causes a good amount of heat no matter the equipment used. In our little phones, it's going to be even worse. If you're going to capture long sessions of video with a phone, your best bet is to either turn down the capture resolution, turn off OIS, or both. But regardless, you've got to be mindful that over heating could still happen.

Yeah, I understand. I am just saying I was a bit disappointed in the amount I was able to capture at 1080p in this set of circumstances, basically less than 14 minutes over 35 minutes.

I also wasn't aware that image stabilization could be de-activated - where is that option?
 
My 5x shooting 4k will only shoot video for 5 minutes before turning the camera off due to overheating. I've not tried 1080p yet, waiting for phone to cool down.
 
I too experienced the same issue with my google pixel today. I was shooting something for 10 minutes. The phone started over heating and the finally shut downs. I rebooted the phone and could not play the video (showed error and blank screen). Tried uploading and it didn't work either.
