Telecine is a first place in film production chain, where it is possible to see, measure and do a quality evaluation of transmitted picture, by which it is possible to control the entire shot materials without major increase in postproduction expenses. In this paper, it is given a review on a telecine roll in film production, as well as use of telecine from the beginning of TV up to nowadays. In this paper a structure of film is explained, also possible formats of film picture and film sound, as well as resolution of film picture and video signal are explained. Main telecine suit elements are specified, and pulldown process is explained. Following signal trough a telecine, all main stages of video signal corrections are clarified and system of recording video signal is mentioned. In paper the procedure of quality evaluation of film picture is described by measurement of video signal, according to test charts as a reference value, comparing standard video signal level and video signal level from a telecine calibrated according to light conditions from shooting location. Described differences between levels of video signal are explaining the character of film drift, because of artistically created light conditions, comparing with film material from standard light conditions. By controlling on telecine established differences, it is determined and monitored a quality level of the shot film material from the same location. From all stated, a quality level of shot film material is maintained if determined differences are approximately constant value during the whole process of film making.
