I don't understand. According to the article, the format uses a "single, central perforation". Wouldn't this kinda annoying to always see perforation in the middle of the projected picture? I guess this is not the case, but the article really makes it sound like this.
The shutter blade should minimize this. Otherwise, in regular 8 and super 8 film you would see the black top/bottom margins, but you do not because of the shutter blade.

9,5 mm film -> 9.5 mm film - Decimal point rather than comma seems to be the dominant formatting by English speakers. (See also decimal separator.) Girolamo Savonarola 04:20, 3 January 2006 (UTC)
The claim, "The width of 9.5 mm was chosen because three strips of film could be made from one strip of 35 mm film." is a very dubious. A better choice, if this was the reason, would be 11.5 mm. With that width, less of the 35 mm would have been wasted (in fact only 1+1⁄2 mm as opposed to 6+1⁄2 mm). DieSwartzPunkt (talk) 16:55, 4 March 2015 (UTC)
One thing that is not covered in any history I have been able to find is the nature of 9.5mm film at its introduction. We know about when it was introduced, but when and by whom was it conceived? Was it originally conceived as a reversal film or is that something that was adopted after Kodak introduced 16mm reversal in 1923? If the former, who has knowledge of the system's development? Did Pathe set up commercial processing stations at the beginning, or was the film originally supposed to be home processed? All of these things should be addressed.

I have since found a little more information, but conflicting from different sources. The most likely says that the projector was introduced in time for Christmas 1922 and that the camera and reversal film were announced in April 1923. Still like to know how it came about. Was Pathe's reversal process in answer to the system Kodak was about to introduce, or did it come about independently? There seems to be little detailed company history, but my instinct tells me that because Kodak and Pathe were close, Pathe was probably aware of the reversal experiments from fairly early on, and initiated their own. It's not something you develop overnight. PastReflections (talk) 02:19, 28 September 2019 (UTC)
