These have dealt with the picture quality obtainable by various printing techniques and the sound quality obtainable by photographic and magnetic methods. Suggestions have been made for changes in perforation size to permit improvement of sound quality. These publications have emphasized the difficulties encountered in obtaining satisfactory quality in 8mm release prints, and have led us to consider many additional factors which may influence quality. Optimum utilization of the 8mm sound color print area requires consideration of such factors as minimum practical perforation size, optimum perforation pitch, maximum picture area and appropriate position of picture, type, positioning and economics of the soundtrack, and similar factors. A number of these factors are discussed. Although many problems are anticipated in reaching a decision concerning a modification of the 8mm format to obtain improved picture quality consonant with a suitable soundtrack, it is felt that these can be resolved to afford better results than are obtainable using the present 8mm format. The study and evaluation of the many factors involved will require critical consideration.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J09331.xml)", "source": "parsed", "updated": "2026-05-22T19:19:44.900Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ { "affiliation": "Research Laboratories, Eastman Kodak Co., Rochester 4, N.Y.", "name": "C.
