Slow Motion

Learning outcome P1

Theory

Slow motion in photography is realized by increasing the picture frame rate when recording and playing back the resulting film at normal speed.

The picture frame rate, is a term used in film and video technology. It describes the number of individual images that are recorded or reproduced per time period.

The human brain perceives successive images as a moving scene starting from around 14 to 16 frames per second. In the beginning of moving pictures (silent movies) 16 frames per second were set for this. With the introduction of the sound film, the frame rate was fixed at 24 Hz.

With my low budged Panasonic bridge camera I can take videos in 1280×720 with a picture frame rate of 100 pps. In video resolution 640×480 the camera can take 200 pps.
