Le Prince also recorded trams and the horse-drawn and pedestrian traffic on Leeds Bridge, [43] and a few more short films. Le Prince used paper-backed gelatin films for the negatives, from which the paper could be peeled off after filming. He also investigated the possibilities of celluloid film and obtained long lengths from the Lumiere ...
Sound-on-disc is a class of sound film processes using a phonograph or other disc to record or play back sound in sync with a motion picture. Early sound-on-disc systems used a mechanical interlock with the movie projector, while more recent systems use timecodes.
The film also used the first "reverse angle" cut in film history. [64] The following year, Williamson created The Big Swallow. In the film. a man becomes irritated by the presence of the filmmaker and "swallows" the camera and its operator through the use of interpolated close-up shots. [65]
In the early 1920s, Western Electric was developing both sound-on-film and sound-on-disc systems, aided by the purchase of Lee De Forest's Audion amplifier tube in 1913, consequent advances in public address systems, and the first practical condenser microphone, which Western Electric engineer E.C. Wente had created in 1916 and greatly improved in 1922.
The 1920s was also the decade of the "Picture Palaces": large urban theaters that could seat 1–2,000 guests at a time, with full orchestral accompaniment and very decorative design (often a mix of Italian, Spanish, and Baroque styles). These picture palaces were often owned by the film studios and used to premier and first-run their major films.

[1] A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films ...
However, this recorder was later adapted for recording speech and was used in 1921 to record speeches by President Calvin Coolidge and others which were broadcast over Station WGY (Schenectady). This recorder was called the Pallophotophone. In 1925, GE began a program to develop commercial sound-on-film equipment based on Hoxie's work.
Phonofilm is an optical sound-on-film system developed by inventors Lee de Forest and Theodore Case in the early 1920s. In 1919 and 1920, de Forest, inventor of the audion tube, filed his first patents on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically ...
