In this paper, we propose a novel user-friendly augmented video compositing and editing system, and we present core functions and GUIs implemented in the system. The core functions consist of image-based modeling, light estimation and shadow generation, and dynamic image-based lighting and rendering. Since the user-friendly GUI dose not require complicate manipulation or special skill level, it enable users to create composed and edited photo-realistic videos by quite simple operation. We present the details of the functions, and show that the system efficiently allows the user to compose and edit given videos.
