A film's sound is just as important as the visuals on screen.
BS 5550-2.4.4 provides you with the specification of width dimensions and lateral positions of the magnetic head gaps in which the magnetic head gaps are physically in line at an angle of 90° ± 5½ to the direction of film travel. BS 5550-2.4.4 also provides the velocity in which the sound records are intended for use at velocities of 24 perforations (approximately 18,3 cm or 7.2 in) per second or at 25 perforations (approximately 19,05 cm or 7.5 in) per second.
Overall, BS 5550-2.4.4 exemplifies the required dimensions and specifications that help you in cinematography.
