2.3 Regular 8mm/Super 8mm (standard 8mm/super 8mm frame) (Motion Picture Formats - original cinematography)
As mentioned above, there are two `varieties' of 8mm film, both of
which are still in use. Both of these varieties are commonly shot
`flat' (i.e. without any `anamorphic' horizontal compression), using
standard lenses.
Several frame rates are used in these formats: films shot for silent
projection (no sound-on-film) are usually photographed at 16 frames
per second (fps), 18 fps, or 24 fps. Films shot for sound-on-film
projection run at 18 fps, or, more commonly, 24 fps. Different cameras
provide different combinations of shooting rates.
Regular 8mm commonly comes in 25' and 50' spools, as well as 100'
spools (although the Bolex regular 8mm is the only camera which takes
the 100' spools). Super 8mm comes in 50' and, less commonly, 200'
cartridges. Most cameras are only capable of accepting the 50'
cartridge, though. Eastman Kodak (tm) once produced super 8mm `sound'
cartridges, which contained film with pre-applied magnetic stripes
along the edges, designed to be recorded in camera. Production of new
pre-striped super 8mm film was discontinued in the fall of 1997, due
to lack of demand.
