The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest as a diode in 1906. Improved, it was patented as the first triode in 1908, consisting of an evacuated glass tube containing three electrodes : a heated filament (the cathode, made out of tantalum ), a grid , and a plate (the anode). It is important in the history of technology because it was the first widely used electronic device which could amplify . A low power signal at the grid could control much more power in the plate circuit.

In the 1950s, many telecine conversions of silent films at grossly incorrect frame rates for broadcast television may have alienated viewers. Film speed is often a vexed issue among scholars and film buffs in the presentation of silents today, especially when it comes to DVD releases of restored films , such as

He soon realized that his "vacuum" Audion had markedly different characteristics from the de Forest version, and was really a quite different device, capable of linear amplification and at much higher frequencies. To distinguish his device from the Audion he named it the "Pliotron", from the Greek plio (more or extra, in this sense meaning gain , more signal coming out than went in). Essentially, he referred to all his vacuum tube designs as Kenotrons,

The German film Tuvalu (1999) is mostly silent; the small amount of dialog is an odd mix of European languages, increasing the film's universality. Guy Maddin won awards for his homage to Soviet-era silent films with his short The Heart of the World after which he made a feature-length silent, Brand Upon
606-645: A much longer time for color to be adopted by the industry and an effective process to be developed. Blue represented night scenes, yellow or amber meant day. Red represented fire and green represented a mysterious atmosphere. Similarly, toning of film (such as the common silent film generalization of sepia -toning) with special solutions replaced the silver particles in the film stock with salts or dyes of various colors. A combination of tinting and toning could be used as an effect that could be striking. Some films were hand-tinted, such as Annabelle Serpentine Dance (1894), from Edison Studios . In it, Annabelle Whitford ,

Warner Bros. was the first studio to accept sound as an element in film production and utilize the Vitaphone, a sound-on-disc technology, to do so. The studio then released The Jazz Singer in 1927, which marked

His 1915 epic The Birth of a Nation used a number of colors, including amber, blue, lavender, and a striking red tint for scenes such as the "burning of Atlanta" and the ride of the Ku Klux Klan at the climax of the picture. Griffith later invented a color system in which colored lights flashed on areas of the screen to achieve a color. With the development of sound-on-film technology and

He then turned his attention to the Audion tube, again suspecting that its notoriously unpredictable behaviour might be tamed with more care in the manufacturing process.

This technique was designed to capture the effect of the live performances of Loie Fuller , beginning in 1891, in which stage lights with colored gels turned her white flowing dresses and sleeves into artistic movement. Hand coloring was often used in the early "trick" and fantasy films of Europe, especially those by Georges Méliès . Méliès began hand-tinting his work as early as 1897 and

Slow projection of a cellulose nitrate base film carried a risk of fire, as each frame was exposed for a longer time to the intense heat of the projection lamp; but there were other reasons to project a film at a greater pace. Often projectionists received general instructions from the distributors on the musical director's cue sheet as to how fast particular reels or scenes should be projected.

Musical scores for early silent films were either improvised or compiled of classical or theatrical repertory music. Once full features became commonplace, however, music
4444-411: The film did not exist, music was seen as an essential part of the viewing experience. "Silent film" is typically used as a historical term to describe an era of cinema prior to the invention of synchronized sound, but it also applies to such sound-era films as City Lights , Modern Times and Silent Movie which are accompanied by a music-only soundtrack in place of dialogue. The term silent film

Early studies by Thomas Edison for his Kinetoscope machine determined that any rate below 46 images per second "will strain the eye". and this holds true for projected images under normal cinema conditions also. The solution adopted for the Kinetoscope was to run the film at over 40 frames/sec, but this

Most early motion pictures are considered lost owing to their physical decay, as the nitrate filmstock used in that era was extremely unstable and flammable. Additionally, many films were deliberately destroyed, because they had negligible remaining immediate financial value in that era. It has often been claimed that around 75 percent of silent films produced in

A number of countries devised other ways of bringing sound to silent films. The early cinema of Brazil , for example, featured fitas cantatas (singing films), filmed operettas with singers performing behind the screen. In Japan , films had not only live music but also
5454-615: The lecturing circuit. The principle of stroboscopic animation was well-known since the introduction of the phenakistiscope in 1833, a popular optical toy , but the development of cinematography was hampered by long exposure times for photographic emulsions , until Eadweard Muybridge managed to record a chronophotographic sequence in 1878. After others had animated his pictures in zoetropes , Muybridge started lecturing with his own zoopraxiscope animation projector in 1880. The work of other pioneering chronophotographers, including Étienne-Jules Marey and Ottomar Anschütz , furthered

His first success was in demonstrating that, contrary to what Edison and others had long asserted, incandescent lamps could function more efficiently and with longer life if the glass envelope was filled with low-pressure inert gas rather than a complete vacuum. However, this only worked if the gas used was meticulously 'scrubbed" of all traces of oxygen and water vapor. He then applied

Lillian Gish has been called film's "first true actress" for her work in the period, as she pioneered new film performing techniques, recognizing
5858-520: The new "talkies" around the mid-1930s. The visual quality of silent movies—especially those produced in the 1920s—was often high, but there remains a widely held misconception that these films were primitive, or are barely watchable by modern standards. This misconception comes from the general public's unfamiliarity with the medium, as well as from carelessness on the part of the industry. Most silent films are poorly preserved, leading to their deterioration, and well-preserved films are often played back at

In 1999, the Finnish filmmaker Aki Kaurismäki produced Juha in black and white, which captures the style of a silent film, using intertitles in place of spoken dialogue. Special release prints with titles in several different languages were produced for international distribution. In India, the film Pushpak (1988), starring Kamal Haasan ,

Originally developed as a radio receiver detector by adding a grid electrode to the Fleming valve , it found little use until its amplifying ability was recognized around 1912 by several researchers, who used it to build the first amplifying radio receivers and electronic oscillators . The many practical applications for amplification motivated its rapid development, and

Three-point lighting, the close-up , long shot , panning , and continuity editing all became prevalent long before silent films were replaced by " talking pictures " or "talkies" in the late 1920s. Some scholars claim that the artistic quality of cinema decreased for several years, during the early 1930s, until film directors , actors, and production staff adapted fully to
7373-515: The silent film era and the era of talkies. Sunset Boulevard shows the disconnect between the two eras in the character of Norma Desmond , played by silent film star Gloria Swanson , and Singin' in the Rain deals with Hollywood artists adjusting to the talkies. Peter Bogdanovich 's 1976 film Nickelodeon deals with the turmoil of silent filmmaking in Hollywood during the early 1910s, leading up to
7474-479: The silent film era that had earned the highest gross income as of 1932. The amounts given are gross rentals (the distributor's share of the box-office) as opposed to exhibition gross. Although attempts to create sync-sound motion pictures go back to the Edison lab in 1896, only from the early 1920s were the basic technologies such as vacuum tube amplifiers and high-quality loudspeakers available. The next few years saw
7575-427: The silents for nearly four decades. As motion pictures gradually increased in running time, a replacement was needed for the in-house interpreter who would explain parts of the film to the audience. Because silent films had no synchronized sound for dialogue, onscreen inter-titles were used to narrate story points, present key dialogue and sometimes even comment on the action for the audience. The title writer became
7676-465: The silver screen. The animated film Fantasia (1940), which is eight different animation sequences set to music, can be considered a silent film, with only one short scene involving dialogue. The espionage film The Thief (1952) has music and sound effects, but no dialogue, as do Thierry Zéno 's 1974 Vase de Noces and Patrick Bokanowski 's 1982 The Angel . Audion amplifier tube Audions had more residual gas than later vacuum tubes;
7777-438: The size of the exhibition site, musical accompaniment could drastically change in scale. Small-town and neighborhood movie theatres usually had a pianist . Beginning in the mid-1910s, large city theaters tended to have organists or ensembles of musicians. Massive theatre organs , which were designed to fill a gap between a simple piano soloist and a larger orchestra, had a wide range of special effects. Theatrical organs such as
7878-413: The space current path greatly improved the sensitivity; in his earliest versions, this was simply a piece of wire bent into the shape of a gridiron (hence grid ). The Audion provided power gain; with other detectors, all of the power to operate the headphones had to come from the antenna circuit itself. Consequently, weak transmitters could be heard at greater distances. De Forest and everybody else at
7979-438: The spot in the manner of the silent-era theater musician. Interest in the scoring of silent films fell somewhat out of fashion during the 1960s and 1970s. There was a belief in many college film programs and repertory cinemas that audiences should experience silent film as a pure visual medium, undistracted by music. This belief may have been encouraged by the poor quality of the music tracks found on many silent film reprints of
8080-476: The stage door, he sees Marguerita and Maurice walking out arm in arm. Blinded with jealousy, Pedro disguises himself as a blind beggar in order to spy on Marguerita. One night as Pedro is playing the violin on the street corner disguised as the beggar, Maurice and Marguerita are attracted by the beautiful music. Marguerita offers to buy the violin, but Pedro tells her that he cannot sell it because he made it especially for an old sweetheart. She sees an inscription on
8181-462: The standardization of the projection speed of 24 frames per second (fps) for sound films between 1926 and 1930, silent films were shot at variable speeds (or " frame rates ") anywhere from 12 to 40 fps, depending on the year and studio. "Standard silent film speed" is often said to be 16 fps as a result of the Lumière brothers' Cinématographe , but industry practice varied considerably; there
8282-419: The telephone industry for at least two decades. (Ironically, in the years of patent disputes leading up to World War I, it was only this "loophole" that allowed vacuum triodes to be manufactured at all since de Forest's grid Audion patent did not mention this application). De Forest was granted a patent for his early two-electrode diode version of the Audion on November 13, 1906 ( U.S. patent 841,386 ), and
8383-404: The time greatly underestimated the potential of his grid Audion, imagining it to be limited to mostly military applications. It is significant that de Forest apparently did not see its potential as a telephone repeater amplifier at the time he filed the patent claiming it, even though he had previously patented amplification devices and crude electromechanical note magnifiers had been the bane of
8484-484: The time. Since around 1980, there has been a revival of interest in presenting silent films with quality musical scores (either reworkings of period scores or cue sheets, or the composition of appropriate original scores). An early effort of this kind was Kevin Brownlow 's 1980 restoration of Abel Gance 's Napoléon (1927), featuring a score by Carl Davis . A slightly re-edited and sped-up version of Brownlow's restoration
8585-547: The title character's non-talkative nature to create a similar style of humor. A lesser-known example is Jérôme Savary 's La fille du garde-barrière (1975), an homage to silent-era films that uses intertitles and blends comedy, drama, and explicit sex scenes (which led to it being refused a cinema certificate by the British Board of Film Classification ). In 1990, Charles Lane directed and starred in Sidewalk Stories ,
8686-629: The traditional approach include organists such as Dennis James and pianists such as Neil Brand , Günter Buchwald, Philip C. Carli, Ben Model , and William P. Perry . Other contemporary pianists, such as Stephen Horne and Gabriel Thibaudeau, have often taken a more modern approach to scoring. Orchestral conductors such as Carl Davis and Robert Israel have written and compiled scores for numerous silent films; many of these have been featured in showings on Turner Classic Movies or have been released on DVD. Davis has composed new scores for classic silent dramas such as The Big Parade (1925) and Flesh and
8787-607: The two papers was reprinted in other journals such as the Annals of the New York Academy of Sciences . When Armstrong and de Forest later faced each other in a dispute over the regeneration patent, Armstrong was able to demonstrate conclusively that de Forest still had no idea how it worked. The problem was that (possibly to distance his invention from the Fleming valve) de Forest's original patents specified that low-pressure gas inside
8888-468: The viewing experience. Among the contemporary ensembles in this category are Un Drame Musical Instantané , Alloy Orchestra , Club Foot Orchestra , Silent Orchestra , Mont Alto Motion Picture Orchestra, Minima and the Caspervek Trio, RPM Orchestra . Donald Sosin and his wife Joanna Seaton specialize in adding vocals to silent films, particularly where there is onscreen singing that benefits from hearing
8989-404: The violin, director Maurice Puello hears the girl play and persuades her to give a recital at his theater. Her first appearance is a great success, and Pedro applauds her from the audience, not realizing she is falling in love with Maurice. Pedro decides to make a special violin for the girl. He finishes the violin, the finest instrument he has ever made, and brings it over to the theater. Waiting by
9090-416: The wire wrapped around the outside of the glass, they caused disturbances in the current which produced sounds in the headphones. This was a significant development as existing commercial wireless systems were heavily protected by patents ; a new type of detector would allow de Forest to market his own system. He eventually discovered that connecting the antenna circuit to a third electrode placed directly in
9191-409: The wrong speed or suffer from censorship cuts and missing frames and scenes, giving the appearance of poor editing. Many silent films exist only in second- or third-generation copies, often made from already damaged and neglected film stock. Many early screening were plagued by flicker on the screen, when the stroboscopic interruptions between frames lay below the critical flicker frequency . This
9292-680: Was a black comedy entirely devoid of dialog. The Australian film Doctor Plonk (2007), was a silent comedy directed by Rolf de Heer . Stage plays have drawn upon silent film styles and sources. Actor/writers Billy Van Zandt and Jane Milmore staged their Off-Broadway slapstick comedy Silent Laughter as a live action tribute to the silent screen era. Geoff Sobelle and Trey Lyford created and starred in All Wear Bowlers (2004), which started as an homage to Laurel and Hardy then evolved to incorporate life-sized silent film sequences of Sobelle and Lyford who jump back and forth between live action and
9393-415: Was compiled from photoplay music by the pianist, organist, orchestra conductor or the movie studio itself, which included a cue sheet with the film. These sheets were often lengthy, with detailed notes about effects and moods to watch for. Starting with the mostly original score composed by Joseph Carl Breil for D. W. Griffith 's epic The Birth of a Nation (1915), it became relatively common for
9494-478: Was controversial, the door had been opened for a new approach to the presentation of classic silent films. Today, a large number of soloists, music ensembles, and orchestras perform traditional and contemporary scores for silent films internationally. The legendary theater organist Gaylord Carter continued to perform and record his original silent film scores until shortly before his death in 2000; some of those scores are available on DVD reissues. Other purveyors of
9595-451: Was expensive for film. However, by using projectors with dual- and triple-blade shutters the flicker rate is multiplied two or three times higher than the number of film frames — each frame being flashed two or three times on screen. A three-blade shutter projecting a 16 fps film will slightly surpass Edison's figure, giving the audience 48 images per second. During the silent era projectors were commonly fitted with 3-bladed shutters. Since
9696-850: Was famous for saying that he "didn't know why it worked, it just did". He always referred to the vacuum triodes developed by other researchers as "Oscillaudions", although there is no evidence that he had any significant input to their development. It is true that after the invention of the true vacuum triode in 1913 (see below), de Forest continued to manufacture various types of radio transmitting and receiving apparatus, (examples of which are illustrated on this page). However, although he routinely described these devices as using "Audions", they actually used high-vacuum triodes, using circuitry very similar to that developed by other experimenters. In 1914, Columbia University student Edwin Howard Armstrong worked with professor John Harold Morecroft to document
9797-403: Was later distributed in the United States by Francis Ford Coppola , with a live orchestral score composed by his father Carmine Coppola . In 1984, an edited restoration of Metropolis (1927) was released with a new rock music score by producer-composer Giorgio Moroder . Although the contemporary score, which included pop songs by Freddie Mercury , Pat Benatar , and Jon Anderson of Yes ,
9898-514: Was no actual standard. William Kennedy Laury Dickson , an Edison employee, settled on the astonishingly fast 40 frames per second. Additionally, cameramen of the era insisted that their cranking technique was exactly 16 fps, but modern examination of the films shows this to be in error, and that they often cranked faster. Unless carefully shown at their intended speeds silent films can appear unnaturally fast or slow. However, some scenes were intentionally undercranked during shooting to accelerate
9999-669: Was released in 1926, would become known for her naturalistic acting. According to Anton Kaes, a silent film scholar from the University of California, Berkeley, American silent cinema began to see a shift in acting techniques between 1913 and 1921, influenced by techniques found in German silent film. This is mainly attributed to the influx of emigrants from the Weimar Republic , "including film directors, producers, cameramen, lighting and stage technicians, as well as actors and actresses". Until
10100-575: Was solved with the introduction of a three-bladed shutter (since 1902), causing two more interruptions per frame. Another widely held misconception is that silent films lacked color. In fact, color was far more prevalent in silent films than in the first few decades of sound films. By the early 1920s, 80 percent of movies could be seen in some sort of color, usually in the form of film tinting or toning or even hand coloring, but also with fairly natural two-color processes such as Kinemacolor and Technicolor . Traditional colorization processes ceased with
10201-454: Was the cause of this outburst from director Marshall Neilan in 1917: "The sooner the stage people who have come into pictures get out, the better for the pictures." In other cases, directors such as John Griffith Wray required their actors to deliver larger-than-life expressions for emphasis. As early as 1914, American viewers had begun to make known their preference for greater naturalness on screen. Silent films became less vaudevillian in
