Took some outside shots with GH2 and noticed these things while masking in Premiere Pro. I suppose those are the results of 8bit footage and codec compression?

Any ideas how to deal with this?
 
The GH2 has a tendency to band colors across a subtle gradient. Not sure if it will assist whatever you're masking, but the colors get a bit better as you increase the ISO towards 640. I've shot skies at 160 and there are rainbow-esque color bands. Shoot at 640 and they'll blend a lot better across the nice textured noise.
 
Thanks for the tips...I always thought lower ISO = better. Since most cameras I've dealt with before looked more horrible every ISO step up.
