A telesync TS [1] is a bootleg recording of a film recorded in a movie theater , often although not always filmed using a professional camera on a tripod in the projection booth. The audio of a TS is captured with a direct connection to the sound source often an FM microbroadcast provided for the hearing-impaired, or from a drive-in theater. Sometimes the bootlegger will tape or conceal wireless microphones close to the speakers for better sound quality. A TS can be considered a higher quality type of cam , that has the potential of better-quality audio and video. The true definition of telesync would include the film being synchronized to the camera's own frame rate and shutter timing as done by television companies when preparing celluloid film for broadcast. A bootleg TS rarely, if ever, uses this form of synchronisation which can lead to additional temporal aliasing.
