I just bought this camera for filming in my kitchen. I thought it would perform well:
>1/1.3-inch CMOS
>Aperture: f/2.8
>ISO Range: 100-12800
>Max Video Bitrate: 130 Mbps

But the footage is awful. I tried at night with the lights on and that looked bad. But even during the day time with all the shades open it's the same quality.

The camera needs to go up to ISO 1600 to expose itself well at a 1/60 shutter speed (using 30fps) and the footage is very soft and glowy. It's not the stabilization, same with it off. It's definitely the aggressive noise reduction. But even setting the noise reduction to -2 (lowest it can go) it's not great footage.

It seems to lose it's sharpness at ISO 800. So the only usable footage is ISO 100-400 before it looks like 480p footage. But that's too dark indoors.

I mean my phone produces a night and day better image in the same lighting conditions. So is it just bad image processing?

Do most standalone cameras just perform terribly at ISO 800+? Or is this one particularly bad? I'm thinking of just returning it.
