The author describes the principles of an approach to video recording that does not use electromechanical components. The basis of the method is that analog modulation, after being converted to digital modulation, is photographically recorded on a film or transparency (square or rectangular), using the principle of matrix scanning. The speed of the scanning is determined by the characteristics of the matrix, type of digital coding, and the length of the recording and is controlled by an electronic clock, such as a quartz clock. The problems raised by this approach are discussed
