To cut the high-ISO noise, do you lower the sharpness to -3?

"Video mode"

Some people have excellent video w/ little noise at high ISO.

The real question is if you film at night with -3 Sharpness, does it significantly remove the noise?  This is what camera companies do to mask the high-ISO issues.  I used to do everything at the maximum sharpness but if the plastic look doesn't exist it's ISO noise and it's not even set that high.

It will just soften the footage

And significantly reduce the ISO noise?  All this tech (type chatting) has lazified me.  I know I can just run a test real quick to see w/ the camera right now.

You don’t control the ISO through the sharpness - adjusting the sharpness to minus will simply soften the image - whether that will make the image look less noisy depends on the lighting conditions and the camera being used.

+0 Sharpness shows less noise than maxing it out.  See for yourself.

I know it does but it doesn't change the ISO

It removes the noise of high-ISO like denoise.

No, it doesn't remove the high ISO noise. It is camouflaging the noise the same way like de-noising in post, more or less, by un-sharpening. Well, de-noising process is a bit more complex than just un-sharpening, but may produce more palatable results when properly conducted. However, always at the expense of detail ...

Very good points - I'm trying to explain to Ant that adjusting the sharpness does not control the ISO but softening the image may reduce the noise in itself.

Again, that depends on the lighting conditions, other profile settings and the camera you are using. Test it with each drone at different times and gauge what works for you.

Do you do -3 for Night shots for denoise?

I use to on the M2P - though I only flew during sunset and never at night

Not that I'm trying to argue, but ....

" ... softening the image may reduce the noise in itself ..."

This is not true. The digital noise is always present, embedded in image forever. The higher ISO value, the more noise is introduced. Softening the image will not reduce the noise. It will camouflage the noise instead at the expense of detail (sharpness).

AS in the perception of the noise or as you put it, camouflage. I'm think we are singing from the same page

We definitely do! I'm just not sure that OP is holding the same book ...
