Abstract: A balance of the functions to be performed by the film in obtaining high-quality 8mm release prints is described. Dimensions and experimental results are presented for an improved 8mm motion-picture film format in which the perforations are smaller and closer to one edge while the soundtrack is placed adjacent to the other edge. The space between the perforations and the soundtrack permits a wider picture, which, when coupled with an increase in pitch, yields a film format having approximately 50% more projected picture area. Image sizes are a 1.8 to 1 reduction from 16mm dimensions. The film dimensions and the reasons for their selection are described in relation to both picture and sound quality in a system for making 8mm commercial prints.
