Clip #1 This is not an example clip, I was wondering however if this is an example of Halo artifacts? (the edges around the students portable game thing)
Clip #2 - This is the color banding (I hope) clip. It's 26MB and spans several scenes which each have varying degrees of banding. I have never been able to successfully filter them, or reduce noise without greatly enhancing the visibility of the bands.
These come from Death Note, Episode 1, R1 DVD
