Improving color gradients and static noise!

As it so happens, I just got back from a shoot earlier today in which I had to resort to shooting at ISO 400, 500, 640, 800, and 1000 at times. This was all with the C settings in 60i wrapper (24p was not selected in Ptool). The shots just finished transcoding to ProRes422 in FCP and I must say they look fantastic. Very clean. No noise, no banding, no FPN even at ISO 1000. They actually seem more filmic than the shots I got at ISO 100 or 200 for some reason. I'm really liking this camera now with the improved bitrate. Incredible!

=D I hate to say I told you so... but...

That's what I had been saying when the D90 hit and then the GH1. The lower the ISO, the stranger things get. 320 and above on all of these things seems to produce the most pleasing image.
 
Yep. I was always afraid to increase the ISO because of all the noise. I really think the bitrate increase changes all that. It probably changes everything about this camera. All settings and options need to be re-evaluated.
 
I think, this is just what I THINK though, that there is STILL noise reduction and sharpening in camera even when it's dialed down to -2.

If there's a way to turn it OFF, I wonder what sort of image difference we'll see with banding etc?

In the Zacuto Part 2 Test with ISO's, the banding around the light bulb didn't go away until ISO 1250 on the GH1. Here are the frame grabs from that test:

I did a quick and dirty test last night with various ISO's. You'll notice that the Mjpeg files hold better in the shadows as to codec banding. I feel that if we can get the bit rate to give more attention to the darks/shadows that would be awesome in AVCHD. Also when playing back mjpeg, it records the fine noise more fatefully coming off the sensor- grain like, however the AVCHD codec smooths it out a little more. This just might be that the AVCHD formulas/numbers are still a work in progress.
