The frame size of regular 8 mm is 4.8 mm × 3.5 mm, and 1 meter of film contains 264 pictures. Normally, Double 8 is filmed at 16 or 18 frames per second. Common length film spools allowed filming of about 3 to 4 + 1 ⁄ 2 minutes at 12, 15, 16, and 18 frames per second.
Standard 8 mm film stock consists of 16 mm film reperforated to have twice the usual number of perforations along its edges, though using the same size sprocket holes. There are 80 perforations per foot of film, exactly twice the 40 perforations per foot for 16 mm film, which gives a pitch of 0.15 in (3.81 mm) between adjacent perforations (and ...
First known film is the first film (not including tests) made with the format and intended for release. Negative gauge is the film gauge (width) used for the original camera negative. Negative aspect ratio is the image ratio determined by the ratio of the gate dimensions multiplied by the anamorphic power of the camera lenses (1× in the case ...
The sound was recorded 18 frames in advance of the picture (as opposed to 56 frames for standard 8mm). This short distance of just 3 inches facilitated the relatively compact size of the later sound cartridges. Some projectors used the balance stripe to provide a second channel for stereo sound. Super 8mm was also specified with an optical ...
Although the most common medium format film, the 120 roll, is 6 cm (2.4 in) wide, and is most commonly shot square, the most common "medium-format" digital sensor sizes are approximately 48 mm × 36 mm (1.9 in × 1.4 in), which is roughly twice the size of a full-frame DSLR sensor format.
Single-8, also known as 8 mm Type S, Model II, is a motion picture film format introduced by Fujifilm of Japan in 1965 as an alternative to the Kodak Super 8 format. Single-8 and Super 8 use mutually incompatible cartridges, but the 8 mm film within each cartridge shares the same frame and perforation size and arrangement, so developed Single-8 and Super 8 films can be shown using the same ...
A 35 mm film gauge illuminated with the flashlight of a smartphone.. Film gauge is a physical property of photographic or motion picture film stock which defines its width. . Traditionally, the major movie film gauges are 8 mm, 16 mm, 35 mm, and 65/70 mm (in this case 65 mm for the negative and 70 mm for the release print; the extra five millimeters are reserved for the magnetic soundtr
Some formats are referred to in terms of the ratio "perforations per frame/gauge size" to provide an easy way of denoting size. For instance, 35mm Academy is also known as 4 perf-35mm ; VistaVision is 8 perf-35mm ; the long-time standard Todd-AO 70 mm film is 5 perf-70mm ; and IMAX is 15 perf-70mm .
