Re: Is slow motion dictated by shutter speed?

Normally you shoot video at 2x the frames per second, i.e. if you are shooting at 30 FPS then you want a shutter speed of 1/60 of a second. This provides a very slight motion blur which makes the frame to frame viewing more comfortable and slightly less jerky.

If you plan on creating slow motion in post process using After Effects' "TimeWarp" or the Twixtor plugin, then you want a very fast shutter speed so that the frames are very sharp and distinct. That gives the software better data so that it can calculate the intervening frames.
