Report of Standards and Nomenclature Committee 41 camera men in order to bring the action back to normal when projected fast, and in the majority of studios the cameras are cranked at 85 to 90 feet per minute, though they thought they were taking at 16 pictures a second. President Porter: I should like to point out that according to our rules, any action today is not final ; they rest until the fall convention. Are you ready to act on the recommendation of the committee that the taking speed be 24 per second for sound pictures ? (Motion seconded and carried) Mr. Jones : Projection speed to be 24 pictures a second for 35 mm. film. (Motion seconded and carried) May I have the first slide again? The third item relates to the position and width of the sound track area on positive film as specified by this dimension drawing (indicating).

Mr. Jones: Item 4 relates specifically to the location and width of the sound track. We are not proposing any standard dimensions for picture area. If I am not correct in that, I should like Dr. MacKenzie to refer to this. Dr. Mackenzie: Mr. Jones is correct, and the question raised was left open by the sub-committee because certain people feel that the space should be black and others think it is not necessary. In such printers as the Western Electric Company uses one part is light and the other is dark, and it is generally accepted that the sound track itself should be 100 mils wide. For the variable area, as made by the RCA, to accommodate their sound track, it should be a track narrower than 100 mils, bordered by
