I finally got a chance to try this out with a DNG that had a fair amount of moire in it. The subject was a fine pattern (think jeans or backpack), the moire was pretty obvious.
Lightroom, Resolve, and PhotoNinja all look the same to my eyes as far as debayering goes. But someone with a more analytical view on this should do comparisons.
LR4's chroma noise reduction removed a fair amount of the chroma aliasing/moire but still left something to be desired.
PhotoNinja, however, removed damned near one-hundred percent of the chroma aliasing/moire and I sincerely cannot tell if it's impacting overall detail. Like, there's no moire whatsoever. Unfortunately, I can't export the actual DNG or a full res JPEG because I do not have a license, but here are screenshots from PhotoNinja, before and after. his was "test" footage from last November so Moire COULD be improved in the new firmware, I don't know how that would work but:
Before PhotoNinja, DNG straight out of camera, 28/1.8 Canon I think:
After PhotoNinja Noise Ninja Reduction, Chroma all the way to the right, detail slider at 0:
Click either photo for a larger PNG screenshot and judge for yourself.
I can also send this DNG for someone to try chroma reduction in Resolve. If Resolve 9 can do this just with chroma noise reduction* then I think my final issue with this camera is ... well... resolved.
*I understand that this is not a moving set of images, and that may also have an effect on how it works in Resolve 9. I would rather do everything in Resolve, to be honest, as the other software do not export DPX or similar. =[
