Displaying control points over a timeline

摘要

On a display monitor (102) the first region is displayed representing a first timeline (601) showing transitions between a first set of image clips. A second region is displayed representing a second timeline (602) showing transitions between a second set of image clips. Control points (621,622) are displayed over said first timeline (601) and over second timeline (602). The location of the control points controls an effect upon a first clip (601) and upon a second clip (602).
