Hi all,

I have been going through some test shots I taken under different settings and noticed a noise reduction option.

For those who not know, under Video-Pro mode you have an option for Noise Reduction.

I presummed this is a function to smooth out high ISO noise. But is it?
I compaired my test shots under low light and there was a slight difference in sharpness (option on is a tiny bit blurier) but not much of noise reduction effect on both.

So I suspect it might be a sound noise reduction function for a mic to reduce wind noise or similar. But in comparison of shots in windy situation, shows not a listenable difference.

So what is it really for?

It is noise reduction for the microphone.

Is it ? I am not sure?

Could be wind noise reduction or some sort of rolloff control but it's the usual fun of trying to decipher Chinese translated menus..

Hi Tide, the Noise Reduction is about the audio, please let us know if you have further concern.

Ok great- but can you share *what* is does - what noise it is meant to reduce?

It mainly will reduce the noise of the environment.

Can we turn off audio noise reduction always without pro mode? I think it changes all the sounds too much except for the voice.
