In another forum, there was a discussion about shutter speed and frame rate. I realized my understanding was limited, maybe even ignorant.


I found a video that helped and I think I almost get it.



What I can't figure out is why my camera lets me shoot 60 frames per second and allows me to set 1/30th of a second. The math does not seem to work. To get 60 frames at 1/30th it should take 2 seconds!


Thanks...

That's only for people who really must have the best low light abilities possible. Low shutters should only be used for low frame rates such as 24p and 30p unless your camcorder does only 60i or 60p. You can do it but it's sort of a catch 22 situation. It gives you more light but your essentially cutting frames away.

I have three camera/camcorders that are always set at 1080p60. Perhaps I should try the catch 22 and see how the frames are cut away.


Thanks.

Yep, you effectively have 30fps in a 60fps stream. If you want to have full 60fps you should not go lower than 1/60. But you may want to do so to improve sensitivity when you really need it. Or if you deliberately going for the effect. Remember train scene from Risky Business? Starts at 3:40.
