Sharpness has nothing to do with frame rate.

"Sharpness has nothing to do with frame rate." ...
Are you sure ? So, all people who saw The Hobbit in 48p HDR are wrong, and all the people that are crazy about 60p/50p because is sharper (also with better motion) than 24p/25p/30p are wrong ? Peter Jackson about 48p vs 24p: 48p is "incredibly vivid, realistic looking image. And you've got sharpness because there's no motion blur, so everything is much sharper."
The sharpness depends mostly by other things (I can tell you which factors increase the sharpness, but you can find if you look at the professional camcorders) ... but frame rate is one of the things that help the sharpness, mostly in motion scenes, but also in static scenes (I know that is hard to believe in theory) ... it's about how compression works.
You don't see a RAW image, but a (heavily) compressed H.264/MPEG-4 AVC in AVCHD cameras (in the case of A99).
About A99: 60p/50p need more bit rate, so 60p/50 in AVCHD is at 28Mbps, and 24p/25/30p at 24Mbps. This higher bit rate (from 60p/50p) also helps the sharpness.
Other thing that helps the sharpness: in AVCHD, 60p/50p need at least Level 4.2, while 24p/25p/30p needs at least Level 4. Level 4.2 is better in everything, including sharpness, than Level 4. About these levels:

You want to say that 48p is NOT sharper than 24p in The Hobbit ?
Many people talk these days about how "sharp" "clean", 48p is:

Also, check the critic's comments for The Hobbit, how clear is 48p vs 24p:

You can watch at cinema both versions 48p (in fewer cinemas) and 24p.
