Since he shot it at 48 fps with a 270 degree shutter, in theory it (the 24 fps version) should look like a 24 fps film shot with a 135 degree shutter (ie. a slightly shorter shutter than normal). 270/2=135. Films normally use a 180 degree shutter. So, using every other frame of the 48 fps original in this case (assuming nothing else was done) would give slightly less blur for the 24 fps version than in a normal 24 fps film, and therefore slightly more strobing.
Normal 24 fps films: 180 degree shutter (normally). Shutter is open 1/48th of a second per frame.
The Hobbit 24 fps version: 135 degree shutter (270/2=135, if they used every other frame of the original 48 fps version). Shutter is open 1/64th of a second per frame. A little bit less blur (unless they added some fake blur) and more strobing.
With even shorter shutters (eg. 45 to 90 degrees) it would have a "Saving Private Ryan", "Gladiator (battles)" or "Robin Hood (2010) (battles)" type look.
Now I understand how those effects are made.
Fast shutter speed played back at 24 fps, (less blur per frame) = strobing effect with fast movements.
Slower shutter speeds played back at 24 fps, (more blur per frame) = more fluid motion during fast movements.
I've always said, the 3-D HFR format would be great for porn and sports because of the realism portrayed by that format. Soap Operas would not fair because the portrayal on those afternoon shows pictates unrealistic situations and would come across even worse in the HFR format (3-D or flat) than they already do!
On the other hand, 3-D HFR could also be useful at major Amusement Park Attractions such as Disney Land, Universal Studios, Kings Island and for documentaries.
At the end of the day, I personally believe the HFR (3-D or flat) format is horrible as a movie presentation format.
