Artifacting on small moving objects on presets 12-10
On presets 10 to 12, there's very noticeable artifacts around the snowfall against the sky in this clip. These kinds of artifacts seem to be characteristic to these faster presets, since they are reduced with preset 9 and basically gone with preset 8 (when normalized for VMAF).
