Abstract
There are at the present time two standards of 35 mm. film perforation, one known as the Bell & Howell perforation for negative films and the other the rectangular perforation for positive films, both of which have been approved and adopted by the Society of Motion Picture Engineers. Unfortunately, the use of these two standards introduces complications found detrimental in certain types of work, which indicate the advisability of having a single standard. It is felt that the rectangular style of perforation has advantages that it is desirable to retain. An alternative standard is proposed that will combine the advantages of both the present styles, and which, at the same time, can be used on practically all existing equipment without alteration of that equipment. Means are also suggested for shortening the transitional period of such a change-over.
