So i understand the use of shutter speed for video but for picture I'm a little confused, like i understand that the faster the shutter speed the sharper the image but why are the uses for really high shutter speeds for example what would i use 1/1000, or 1/8000 shutter speed for or is it just there so that nikon can say it can. what is even the point of 1/500? would you ever use this for video? sorry if i sound a little clue less but i can't find it out anywhere
Shutter speeds were designed for photo so you can freeze action. 1/1000 will look the same as 1/8000 but at 1/8000 you could have an aperture of say f2.8 while at 1/1000 youd have to be at like f5.6 so you could play with your DOF.
As for video, you can shoot higher shutters but some people dont like it. I used to shoot 1/100 0 an 1/2000 alot but now i stick to 1/180 and 1/250.
for 60p... i dont shoot 24 very often unless its for a certain situation, im normally shooting skiing which i shoot 60p. I may bring it down to like 1/96 for 24p. I also use and ND filter so that i can keep my aperture between 2.8 and 11.
