SONY A6300 Video Test 2 (S-Log2/PP7)

Compare to RX10 II, graded S-log2 clips are generally far less noisy and thus much more usable. However, in some cases, I experienced heavy chrominance noise and banding in some scenery clips (not included in this clip). I am still testing and understand the exact behavior. I wonder if it is the issue suggested by some video forum.
