The story of 8mm
Home video making begun in 1932, when Mr. Eastman Kodak announced the 8mm film format. 8mm was a cheaper, more portable alternative of the 16mm film format. Around those times 9,5 mm films and recorders were still available. 8mm is a step back in picture quality but in prize too. It`s cheapness and the advertising campaign convinced the people to buy the new 8mm recorders. This decision meant the end of 9,5 mm filming.
Normal 8 film is a 16mm film, perforated on both sides. User had to expose the two sides, then came the processing, and the cutting in the middle. After this there were two 8mm films.
One spool (15,2m) with 7,6 cm diameter contains 4 minutes at 16 frames per second.
Normal 8 was followed by Super 8 in 1965.
-50% larger image size;
-18 or 24 frames per second;
-Easy film refill with cartridge;
-Battery powered cameras.
These had not got such a stable image as the N8, but at least was not rewindable. In this case it is an advantage; many footages were ruined by accidental rewinding. Sad news for video enthusiasts: tricky crossfade effects were not available anymore.
Super 8 with sound
In 1973 Kodak refreshed the technology; they developed the sound able version of the Super8. The camera could record sound on the tape`s magnetic row. Customers were able to record with 24 frames per second, this was close enough to cinema feeling. S8 reels were produced until 1997. By many opinions Kodachrome gave the best picture quality. These rolls have great colors even nowdays too. The low quality materials, the bad storage conditions, made the recordings worse year by year. Most frequent problems are: tape mould, color transformation to red or blue. The red or blue colors can be reduced, but will not disappear from the film.
