 Three frames of 9.5mm film showing central sprocket holes 9.5 mm film is an amateur film format introduced by Pathé Frères in 1922 as part of the Pathé Baby amateur film system. It was conceived initially as an inexpensive format to provide copies of commercially-made films to home users, although a simple camera was released shortly afterwards.

Pathé or Pathé Frères is the name of various businesses founded and originally run by the Pathé Brothers of France. ...
It became very popular in Europe over the next few decades and is still used by a small number of enthusiasts today. Over 300,000 projectors were produced and sold mainly in France and England, and many commercial features were available in the format.

The format uses a single, central perforation (sprocket hole) between each pair of frames, as opposed to 8 mm film which has perforations along one edge, and most other film formats which have perforations on each side of the image. The single hole allowed more of the film to be used for the actual image and in fact the image area is almost the same size as 16mm film. The perforation in the film is invisible to viewers as the intermittent shutter blanks off the light as the film is pulled through the gate to the next frame. In most 9.5mm projectors, the shutter also operated once whilst each frame was stationary in the gate to increase the apparent frame rate. In the later sound films, a 1 mm magnetic soundtrack was added, reducing the width of the image by 1 mm. 8 mm film is a motion picture film format in which the filmstrip is eight millimeters wide. ...
In photography, a shutter is a device that administers the exposure by admitting light to the film for a specific period of time. ...
Frame rate, or frame frequency, is the measurement of how quickly an imaging device produces unique consecutive images called frames. ...
The width of 9.5 millimeters was chosen because 3 strips of film could be made from one strip of 35 mm film. This was useful when duplicating films because only 1 strip of 35 mm had to be processed. Then the sides, which contained the 35 mm sprocket holes, were cut off, the remaining film was cut into 3 strips, and the central sprocket holes added to each new strip. A millimetre (American spelling: millimeter), symbol mm is an SI unit of length that is equal to one thousandth of a metre. ...

The projection system also incorporated a way to save film on non-moving titles. A notch in the film was recognised by the projector which would then project that same frame for 10 seconds. By this method, 10 seconds of screen time was available for 1 frame of film, rather than the 160 frames required if the film was projected at the normal rate.
