Noise in UHD?

[Larry Chapman]

I'm seeing more noise in some UHD footage that I expect.

1) Shot in UHD 29.97 100M
2) Dropped into a 720P timeline (Premiere) with scale at 100% (so it's pushed in) and rendered in 720P.
3) F/W 1.81
4) Normal mode (not HIGH SENS)
5) 0Db gain
6) Iris WIDE
7) Scene file 4 "Still like" with NR at 0.

I think what I'm seeing is high frequency noise (swimming small black dots)....look at the wall near the pictures. What I see in the Premiere program monitor is nearly identical to what it renders.

Thoughts?

Noise is there for sure. What happens with the camera on auto?

Here is an example with the camera on auto and shooting UHD/60fps/150M. Again, no gain, "still like" scene 4, NR at 0. It's worse! I hope someone can tell me what I did wrong.

Better Manual 30 fps ISO250 / 500 Exposure 1/30 or 1/60, possibly GR control +2 or +3,
Aperture open at this light as I see on your example times this direction go.
