Thnx for the shootout! However, while there are indeed differences (when you view side by side at 200% and really know what to look for - pixelpeeping) this quality increase is really not THAT significant at all.

The differences in 'stairstepping' around edges is hardly noticable, even in this worst case scenario where you have the black background, red shirt and look at 200%!

Sometimes (like here) technical details are exaggerated (Look mum, if I press and hold this button, turn my camera up while running and select frame 374...) You get the point... It's forgotten how this 'problem' translates into real movies, music clips etc. (if being a problem at all in the first place!) I mean, we're not making movies for the technical guys at ILM

And if there is a problem with the EX1 codec which the Nano fixes, it would be the motion artifacts on specific scene's (water, leaves that move because of wind and pans in other shots with very fine detail...) This keying example however just doesn't look like that 'significant' problem that needs fixing. At least not for 3000 dollars :)
