Abstract: Authoring quality video content is difficult since proper camerawork is required for delivering content which appropriately reflects user’s expressive intentions. Based on an experimental result on non-expert users, the incremental interaction model was formerly proposed. The authors propose a system based on the model which compensates for user’s lack of cinematographic knowledge or skills by relating affective information such as atmosphere or mood to shooting techniques. After selecting a specific type of atmosphere to express non-verbal information, the system analyzes the shooting image and the camera operation including the camera angle and the zooming speed to assist the user. The appropriate parameters for shot sizes, camera angles and zoom speed are based on the analysis of extracted features from ten highly-evaluated films. The system evaluation has indicated that the system assists the user in reflecting user intention of the shot appropriately; therefore it enables the user to capture shots more appropriately and effectively without cinematographic knowledge or skills.
