Slow-motion is relating to or being motion-picture or video photography in which the action that has been photographed is made to appear to occur slower than it actually occurred. It is the process of remapping the time in the film. It was invented by the Austrian priest August Musger in the early 20th century. Slow-motion is generally used in dramatic or action scenes in movies or science and nature shows on TV. Shooting slow motion is generally the easiest method to accomplishing slow motion as little to no processing work is needed, however, this is usually the most expensive. Expensive cameras, such as Bolt or Phantom, are generally required to shoot higher frame rates as cheaper consumer cameras do not have this capability. It's especially useful in tabletop industry.

How to make slow-motion videos?

Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. A term for creating a slow-motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow-motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay than to film. A third technique that is becoming common using current computer software post-processing (with programs like Twixtor) is to fabricate digitally interpolated frames to smoothly transition between the frames that were actually shot.
