Shutter speed

 Shutter speed is the speed at which the shutter within the camera closes to take a photo if you have a high shooter speed you are more likely to capture moving subjects. High shooter speed settings are typically seen in sports videography or on sports photographers cameras as they have to capture every moment that is happening and things on screen can change quickly.

This screenshot is from 60 shutter speed which gives the vide a blurry effect on the moving object. This effect can be used in films but if you don't want it you will need to up the shutter speed which could effect other settings, it is important to take this into consideration before filming. 

This screenshot is taken at 125 shutter speed and although still not clear it does show the difference as you can see more detail on the object in motion as well as the hand while it is being swung.

When recording something in high shutter speed it will make the subject look frozen as you are closing the shutter very fast and capturing similar to a freeze frame of the subject. This means if you are trying to record something and show that it is moving fast having a very fast shutter speed is not the best way to film it, instead you should choose a slightly lower shutter speed as it will add a little blur and make the subject look like they are moving fast.
