technically, blurring only occers for fast moving objects. its a way for the brain to sense motion and determine where something came from as well as speed, and our eyes are limited to a refresh of 30hz which increases to 60hz as you go towards perphiral vision. slo-mo motion blur would not occer. if anything, normal motion blur (ie see in the game during normal time) would be the only blur visible. though since this would make things more difficult to see (since the blur is more apparent then it was during realtime) we would have a more difficult time viewing the action. not to mention the massive increase in fillrate by an inverse factor of the timefactor used in the slomo. this increase owuld cause framerates to dip heavly during a slmo sequence since you need to blend more frames together, since effectivly you should be be blurring an avg of frames that occer in a certain time range. this time range (ie exposure time) would now have more frames then before (since time is slowed, frames per time unit increases). this is basically saying we are using a high speed camera (ie less blurring) and playing the frames back at "normal" speed.

retend we have a 20hz camera and a 100hz camera. now if we play the 100hz action back at 100hz its normal speed. if we play it back at 20hz we get slomo with sharp images. if we playback the 20hz at 100hz, we get fast motion. if we play back the 20hz at 4hz we get blurred slomo (since we are just showing frames longer then they should, just like the 100hz "film'' at 20hz example). starting to see how things change?

games tend to have cameras that are "perfect" )ie not blur at all), since motion blur is costly. even with some minimal motion blur, it appearence would not increase during slomo time, it merely seems increased due to seeing the normal frames of animation longer then usual.

long story short, motion blur while looking cool, would only be realistic if motion speed was increased. also even if added to slomo, it requires an increase in fillrate.

I have a brainwave about how to implement bullet-time in multiplayer. You design it as an area effect that is triggered by a player at a certain location . Bullet-time is then experienced as a speed modifier (exponentially) proportional to the distance from that location. To give the player responsible an advantage, you then allow them a slight positive speed modifier within that bullet-time bubble!

This way, you can have bullet-time with any number of players!

Yeah, I think area effect is the best way to go. It should be limited, and maybe you''d have two dimensions, normal speed and bullet speed. When players or objects are in a bullet speed area they slow down unless they enter bullet time themselves. Depending on how long bullet time lasts you could end up with cool fights where everything (bullets, cars, other moving stuff) except the players is in slow mo.

Better still, make Bullet Time part of the story. Make it so your lead character is holding some magic crystal that allows him/her to slow down time for the party. You could weave the crystal into the plot as some major plot element.
