what determines amount of motion blur??

i was curious as to how i can figure out how much motion blur will be picked up by a certain camera setting. Im quite new to cinematography and i will be filming a dance video soon and i want to make sure i dont set the camera incorrectly so there is loads of motion blur. Is there at all a way of fine tuning how much motion blur you will get when setting up the camera, i think its something to do with shutter speed and exposure??? but im not sure
could someone please enlighten my poor old brain - by the way i am using the sdx 900.

On a video camera, if you're trying to emulate the motion signature of film, you want 24 frames per second and a shutter speed of 1/48. I think some consumer cameras try to make themselves more sensitive by just having no shutter and exposing for the entire frame duration, which doubles motion blur and in my opinion makes everything unpleasantly smooth.

You also want to take care not to have too little motion blur. Without motion blur, there is no illusion of motion, and your film looks like a very rapid sequence of still frames.

Since you're shooting on video, you can do an instant test. Pick your frame rate and exposure time, shoot some motion, do some pans, and look at it. Try a few combinations and see what you like. When you've decided, just rewind and record over your tests.
