This is an example of Video Artifact Premium motion denoise filters. The original video is a Full HD file from Nikon 1 V2.
I used 6 motion denoise filters with different settings for Y, U and V channels separately.
Difference / Before / After
The denoise result, 1x crop. Patches of light are changed because of influence of motion denoise filters.
Note: YouTube has additional denoise and high compression. Download mp4 file to see actual quality.
