The paper describes a method for analysing a sequence of images by building static images, representing the environment on which shapes move. From the background and moving objects it is possible to reconstruct the original image sequence as well as to generate new ones. The analysis uses a linguistic interface that allows to express the semantics of video's. Both background and movement analysis allows to extract the shapes contained in a video. The description of video shapes and of their spatio-temporal properties is performed by a Prolog program; so the program using facts describes the Syntax of the video's, while the layout of predicates contains the description of the semantics. Then the content of a 'video-base' may be extracted: the approach uses a prototype film, whose description is used as a dynamic query for automatic extraction of other film semantics.
