In this case, the sprocket wheels engage film perforations in the film stock.
The Commission's logo is a multi-color graphic based on a traditional Serbian weaving pattern featuring film perforations.
Fourth, it can cause subsequent processing difficulties for the negative, because the registration pins will be engaging the film perforations on their opposite sides to normal.
Pulldown claws - number of claws which engage the film perforations to transport the film while the shutter is closed.
Registration pins - number of pins which engage the film perforations during exposure in order to ensure consistent image stability from frame to frame.
Negative pulldown is the manner in which an image is exposed on a film stock, described in the number of film perforations spanned by an individual frame.
It was the first film to demonstrate the Theatre Optique system developed by Reynaud in 1888, and is also believed to be the first usage of film perforations.
Cine 160 is a 35 mm film projection process proposed by Allan Silliphant whereby a single frame of film would occupy a length of six film perforations.
Most cameras use pulsed timing marks along the edge of the film (either inside or outside of the film perforations) produced by sparks or later by LEDs.
Film perforations, also known as perfs, are the holes placed in the film stock during manufacturing and used for transporting (by sprockets and claws) and steadying (by pin registration) the film.
The tape may be pre-perforated for the film perforations, or the splicer may make perforations as the splice is made (this type of splicer is sometimes referred to as guillotine splicer).
They patented a number of significant processes leading up to their film camera, most notably film perforations (originally implemented by Emile Reynaud) as a means of advancing the film through the camera and projector.
Silent films were shot at a 1.33 aspect ratio (also known as a 4:3 aspect ratio), with each frame using all of the negative space between the two rows of film perforations for a length of 4 perfs.
The results of the meeting were an agreement no longer to sell films, but only to lease them for four-month contracts, only to rent films to members of their own organization and to adopt a standardized film perforation count on all films.
There are various, albeit minor, technical differences in the film perforations between Kinopanorama, which at the time of its invention was milled to accept the Kodak Standard (KS 1866) 'positive perforation' 4740 short-pitch camera negative stock, and those of the Cinerama and Cinemiracle cameras.
Film perforations were originally round holes cut into the side of the film, but as these perforations were subject to wear and deformation, the shape was changed to what is now called the Bell & Howell (BH) perforation, which has straight top and bottom edges and outward curving sides.
Stereo optical sound prints are compatible with films with any aspect ratio and with normal print film stocks with KS-type film perforations, whereas stereo magnetic sound prints require film stocks with the narrower CS-type film perforations.
