SMPTE

This standard specifies the dimensions of 1-in video magnetic recording tape, and the direction of magnetic orientation.

This standard specifies dimensions for the width, thickness, and width deviation of raw tape stock used to record reference tapes for 1-in helical-scan video tape recorders. Conditions before testing and testing environment are also specified.

This standard specifies test conditions, general video record system, video pole-tip locations, scanner parameters, scanner-guide locations, and the tape tension for 1-in type B helical-scan video tape reference recorders operating on the 525/60 monochrome or NTSC color systems.

This standard specifies the dimensions and location of video, audio, and tracking-control records on reference tapes for 1-in type B helical-scan video tape recorders, operating on the 525/60 monochrome or NTSC color system, as described in ANSI/SMPTE 29M.

This standard specifies the cutting and perforating dimensions for 35-mm motion-picture film having two rows of 16-mm type perforations, one row near each edge of the 35-mm film, and a perforation pitch of either 0.2994 in or 0.3000 in (7.605 mm or 7.620 mm). The width of the 16-mm strip after processing and slitting is also specified.
