Video / Motion / Animation / Film
About
A video is :
- a sequence of image called frame
- shown at the frequency called frequence rate (per second)
- compressed to follow a bitrate.
Movies at first were called moving pictures. A good example to see is the Garden Scene 1888 (The oldest fragment of film shot in Roundhay, Leeds, UK by Louis Le Prince.
In fact, motion is an illusion created by quickly changing static images at a consistent speed. In a movie/video context, this image are referred as frames.
