Selecting the Filming Speed
The filming speed selector sets the number of frames to be fed per
second. Turn the filming speed selector and set the index to the
desired filming speed graduation. 18 fps is the standard filming
speed for Super 8 cameras.
■ When shooting at 54 or 35 fps, the motor requires a sufficient power
level of the batteries.
■ Do not turn the filming speed selector while depressing the shut­
ter release button.
■ The camera will function properly only at the graduations on the
filming speed scale.
■ Avoid operating the camera at high filming speeds when film is
not loaded.
Filming Speeds and Projection Effects
Film shot at filming speeds other than the standard speed of 18
fps will have varying effects when projected.
1 When shooting at high filming speeds of 54 or 36 fps, the pro-
I jected pictures will have a slow-motion effect. For example,
when a film is shot at 36 fps and then projected at the standard 18
fps, the projecting time will be lengthened by two times, thereby
slowing down the speed of motion by one-half. High filming speed
is, thus, very effective when slowing down fast moving subjects or
when analyzing movements. Exposure time is also speeded up and
is, therefore, effective for eliminating blurring during panning. 24
fps is also used for shooting standard sound film.
