Original - A closeup of the printing of audio tracks on a 35mm film. From left to right: SDDS, Dolby Digital, analog optical, and DTS time code. The large white rounded rectangles are the film perforations: physical holes approximately 2.794 millimeters wide. Note that the Dolby Digital audio track is printed between the performations.
Reason
