Looking at sky footage I shot with almost the same settings with the same camera, I'd say the noise is normal. It looks a bit worse (blocking) after all the compression. Noise is just a fact of video life, and nobody notices. OK - maybe a couple of people. If you want to get it past them, put a little movement in the scene. Then it is completely invisible.

If you do have a huge still monochrome object in the frame, like an unmoving sky, and your shot lazes upon it for a very long time, with no other interesting things going on in the frame, then the sky detail setting on the camera is made for this. Frankly, though, your camera is ok.

Switch Noise Reduction 2 (NR2) to High and see how you go.

Cheers

I agree.

There is some other ways:
- sharpness set to 0 (-1)
- corring set to 0 (2)
- HDF set to M (from "sharp" L), it is a very good way how decrease a visible noise in the whole picture.
- DHV set to 0

you can probably set NR2 to low, but I don't like this way, becouse this setting remove detail from the whole picture. Try use the sky detail setting rather.

Use ND filtr and F4-4,5, for good sharpness of the glass.

Nope

Noise reduction settings in the camera cause a trailing effect in the image.

Correct - NR 2 does NOT cause a trailing effect.
