About the SmoothCam Filter
The SmoothCam filter reduces unwanted camera movement from your footage, such
as less-than-stable crane or jib arm moves, teetering from handheld walking shots, or
vibrations in automotive shots.
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.
