My tape obsession was already slightly out of control, but when I found

to play these, we're they standardised?
What is the difference between 8mm and super 8, is it backwards
compatible?
Or is this all to analogue to care?
8mm consisted of half of 16mm. It was actually 16mm film, with twice as
many sprocket holes per foot. In eastern europe, supposedly you can still
get 16mm film reperforated!
The camera exposed down one side of the film, and then when done, you
flipped it over to expose the other side. Once it was processed, the film
was plit doen the middle, to create two 8mm films (with sprocket holes
only on one side.) Unexposed film was on 16mm reels, processed film had
an 8mm reel.
Usually at 16 frames per second.
Wittnauer made an 8mm camera that could attach on to a motorized base and
light source to convert into a projector! What am I offered for that
piece of esoterica?
There were even stereo cameras. I'm keeping the matched pair of Goerz
Hypar lenses for another project. I would like to get rid of my 8mm and
16mm cameras, and developing equipment.
Super-8 was a completely different format. Even the sprockets and reels
are different. The film was about the size of 8mm, but squeezed a
larger frame on it. Usually at 18 frames per second.
(16mm sound film is generally 24 frames per second; 16mm silent film
changed from 16fps to 18fps.)
https://en.wikipedia.org/wiki/8_mm_film
starts with an adequate diagram of the difference.
There existed some projectors that could do both "regular 8" and "super
8". Kludge.
Sound existed for both, but wasn't common.
Some 8mm cameras had interchangeable lenses, using "D" mount. (16mm and
some video are "C" mount).
Virtually all super-8 cameras have non-removable lenses, often "zoom".
(Notable exception was Leitz Leicina, one model of which used Leica
"M" mount!, although the few lenses produced for it would not fill a 35mm
frame, and most M-series lenses are too long a focal length to be of
practical use on Super-8) A 90mm lens would probably be about right for
photographing the eclipse. About 40 years ago, I used a 200mm Leica mount
Komura on a Bolex 16mm, . . .
OK, now think about how you would go about transferring 16fps, 18fps, or
24fps to 30 frames per second, . . .
