A method for producing a dynamic lecture video from high resolution video recorded by an HDV camcorder is described. In this method, the high resolution video is cropped to focus on the region of interest, such as the instructor. Because this method uses virtual camerawork modeled on broadcast camera techniques, the generated video is very similar to professional broadcast video. Moreover, by focusing the viewer’s attention on the chalkboard, the generated video is useful for students. We evaluated our method with subjective experiments and confirmed its effectiveness.
