By default, the Video Intelligence API examines a video, or video segments, by frame. That is, each complete picture in the series that forms the video is examined. You can also have Video Intelligence annotate a video, or video segment, according to each shot that it detects in the input video.
Shot change detection annotates a video with video segments that are generated when detecting abrupt shot changes in the video. In the output annotation, the beginning frame of each video segment indicates an abrupt shot change (i.e., the frames before and after that frame are visually different).
To detect shot changes in a video, call the
annotate
method and specify
SHOT_CHANGE_DETECTION
in the features field.
Check out the Video Intelligence API visualizer to see this feature in action.
