JCS - Can you use a base 5DMKIII still as an example and show the different methods of sharpening? Probably a lot of work, but I'm interested.
720p ALL-I from camera:

720p with the above 'manual' USM, followed by Sharpen, followed by custom GPU noise grain (runs real-time):

Sharpening was applied to the 720p video scaled up to 1080p and slowed down 40% (60-24fps). Looks better in motion- can't really tell it was 720p source when watched full screen (including on an HDTV).
