think of it like a still camera... if you shoot at a shutter speed of 1/2000 of a second, you would do that to catch a fast moving object clearly, or you may use such a high shutter speed to control your exposure under extremely bright circumstances to get in the sweet spot of your lens. that's shutter speed.

if you shoot at a rate of 24p or 30p... but you set the slow motion setting in "slow and quick motion" to 60. when you play back the footage recorded at 24/30p the image will play at half the speed or slower. 60fps/24p or 60fps/30p. that's slow and quick motion or frame rate converting.

sorry i am sure someone else can probably state this more simply but i think that's the gist of it.

hope it helps

Olof and Greg - - thank you. I finally understand.
And Tito, I appreciate the link... I'd checked out some stocks like this, but I have to shoot Canadian coins, so I'm going to have to get the footage myself.
Cheers everyone, Malcolm
