Abstract This paper proposes processible video codec on camera operations (PVCC) which uses two video data (camera parameters and image contents) to improve the efficiency of video editing. Image data are separated in the coding; they are selected and synthesized in the decoding. Conditions are set for the relationship between the positions of a camera and its object so that data separation is simplified in the decoding. The system using test patterns shows that the system has an average SNR of about 50 [dB] with accurate camera parameters, the value being sharply deteriorated with an increase of errors in the parameters. Simulations of camera operation and data editing successfully confirm the expected effect of the proposed method. A simple language describing the camera improves the speed of video editing and increases content readability.
