How the SmoothCam Filter Works

Unlike other filters in Final Cut Pro, the SmoothCam filter must analyze a clip’s entire
media file before the effect can be rendered or played in real time. Using the
SmoothCam filter requires two independent phases:

 Motion analysis: Pixels in successive frames are analyzed to determine the direction of

camera movement. Analysis data is stored on disk for use when calculating the effect.

 Motion compensation: During rendering or real-time playback, the SmoothCam filter

uses the motion analysis data to apply a “four-corner” transformation to each frame,
compensating for camera movement.
