In the Contents pane, select the video clip for which you want to detect clips.
On the Tools menu, click Create Clips.
The video clip is divided into clips according to the video source. If the video clip is from a DV camera, clips are created based on the time stamps inserted by the DV camera. If time stamps or other file markers are not present, clips are based on each significant frame change in the video. If the video clip is from an analog source, clips are created based on each significant frame change in the video.
