Rar Jay

Yes of course it's multiple frames at different exposes fused together. Tap the shutter button and it's done for you, by a neural network no-less, with AI. And certainly more than just 3 frames fused together, due to the speed of the sensor.
The GFX 100 burst isn't fast enough for this to work.
It does show that small, fast smartphone sensors can overcome shortcomings like dynamic range, with computational photography.
They have never been able to beat a medium format camera, massive 44x33mm sensor with 100 megapixel before.
The Huawei is the first to do this.

R5 seems a good trade off between body size and video recording capability. I think its great to be able to shoot such high spec video in a compact easy to handle system. I shoot travel/active/lifestyle stock footage and rarely need more than 1 or 2 minute clips.  Also like that R5 seems to have Panasonic level IBIS.
For video work, long takes and on-set, I'd use a suitable camera with cooling fans. 
I think those R5 recording times are expected and perfectly acceptable

I’m pretty sure S1H has IBIS from talking to Panasonic rep, not a definitive yes, rather a ‘I can’t say but I’d expect so ?’ answer
I picked up an S1 for £1750 at a store open day, and free V Log! Awesome camera. I’m just using Voigtlander VM 35/1.2 at the moment. Amazed how good the IBIS is compared to A7iii 
I prefer S1 to S1H I think, 10 bit 4K 30p will do me and the camera is smaller without the vents. To be fair, the 8 bit codec already looks superb, 10 bit is a bonus.
