Re: Panasonic G7 Video Noise

What is most clearly visible in your video is Youtube's compression artifacts. Any small noise will be magnified by rough compression, and this is most clearly visible in the black clothing the guy is wearing: large area with only small variation in color and brightness. I am sure the original video does not look at all like that.

In my own G7 4k video, I had earlier noticed only the noise in some ISO 800 footage of deers in fog right after sunrise. The lack of contrast (everything is milky grey) in that video made the noise visible, but not in a particularly disturbing way. It is just small grain-like noise, nothing comparable to what is visible in your Youtube video.

Now I had a new look at my other 4k video. Yes, there is some very minor noise even at ISO 200, but it is so minimal that I had never really thought about it. Much more disturbing than that noise is aliasing artifacts in some 4k footage when viewing on a 1920x1200 monitor (bypassing high-quality scaling from 4k to 1080p.)
