The development of film technology led to film interpolation techniques, which improved the fluidity of “camera motion.” This advancement also made it possible to add sound to films, which was a major step in developing the medium. The next major step was the development of synchronized sound. This development enabled films to use slow motion and improve the overall effect.
Film interpolation techniques improved the fluidity of “camera motion.”
Motion interpolation techniques are a type of video processing that re-creates the motion of a moving image by generating intermediate frames. These techniques are widely used in modern filmmaking and television production and are useful for generating fake slow-motion effects. They can also produce artifacts but can result in smoother motion at slower speeds.
The first film slowed down by 50 times and was produced in 1895, and it was titled “View From the Window At Le Gras.” The Wachowski brothers further developed the technique by creating “bullet time,” a special effect that combines temporal and spatial movement. In addition, engineers at Manex Visual Effects pioneered 3-D visualization planning methods that went beyond mechanically fixed views and introduced digital compositing.
The synced sound was a major step in the technological evolution of film.
The introduction of sound to film has accelerated the technological evolution of slow motion cinematography. Initially, sound on film was limited, with sound machines able to record only a few minutes at a time. The film would jump out of sync if the sound disk was removed or replaced. Hollywood did not embrace this technology, and it was never used in mainstream films. Instead, the sound was translated into light and electrical pulses and hardcoded next to the images.
In 1919, Lee De Forest introduced a method to synchronize sound with pictures. The new method produced a composite print. However, it required perfect synchronization of sound and picture during recording. Theodore Case improved the system in the 1920s.
Using slow motion cinematography in audiovisual screen-based media
Slow motion can be used in a variety of audiovisual media, including movies and music videos. Although the motion can be viewed as a kinetic effect, it can also be used as a means of preserving a historical work. Often, institutions do not have the full rights to make the work available to the public, and this can be problematic. For example, a film might have the rights to be released commercially, and it may not be clear whether the institution has the original.
