Tri-level sync is an analogue video synchronization pulse primarily used for the locking of high-definition video signals . It is preferred in HD environments over black and burst, as timing jitter is reduced due to the nature of its higher frequency. It also benefits from having no DC content, as the pulses are in both polarities. [1]
The first three chapters of Cinema 2, each outlining a number of ways of approaching what Deleuze calls "the time-image". The first chapter explores the works of various filmmakers who were, according to Deleuze, precursors to time-images.
Even in the silent film era, films were shown with sounds, often with musical accompaniment by a pianist or an orchestra keeping time with the screen action. The first synchronization was a turning recording device marked with a white spot. As the white spot rotated, the cameraman hand-cranked the camera to keep it in sync with the recording.
Film theory is a set of scholarly approaches within the academic discipline of film or cinema studies that began in the 1920s by questioning the formal essential attributes of motion pictures; [1] and that now provides conceptual frameworks for understanding film's relationship to reality, the other arts, individual viewers, and society at large.

The most complex part of telecine is the synchronization of the mechanical film motion and the electronic video signal. Every time the video (tele) part of the telecine samples the light electronically, the film (cine) part of the telecine must have a frame in perfect registration and ready to photograph.
Deleuze writes on the multitude of movement-images that "[a] film is never made up of a single kind of image […] Nevertheless a film, at least in its most simple characteristics, always has one type of image which is dominant […] a point of view on the whole of the film […] itself a 'reading' of the whole film".

Pilottone (or Pilotone) and the related neo-pilot one are special synchronization signals captured by analogue audio recorders. Also known as double system recordings, Pilottones were designed for use in the production of motion pictures to keep sound and film recorded and synchronized on separate media.
Errors can also be caused by the projectionist misthreading the film in the projector. Synchronization errors have become a significant problem in the digital television industry because of the use of large amounts of video signal processing in television production, television broadcasting and pixelated television displays such as LCD, DLP and ...
