Title
(EN) PROCESS OF MASTERING AUDIO AND VIDEO USING MOTION PICTURE TECHNIQUES
(FR) PROCEDE DE MELANGE DE SIGNAUX AUDIO ET VIDEO EN UTILISANT DES TECHNIQUES D"IMAGES EN MOUVEMENT
Abstract
(EN)
Method of synchronizing audio and video information wherein standard motion picture techniques may be used to form a master finished audio track accurately synchronized with a recorded video signal. A standard master edited video tape is recorded (12) with a conventional SMPTE time code or other code identifying each of the recorded frames. The video signal and time code are transferred to a first sprocketed magnetic film (29) which operates at standard motion picture speeds. This film serves as a "work" print which is then used to build a plurality of audio tracks which are synchronized with the video information appearing on the work print. Thereafter, the audio tracks are mixed to form a master finished audio track on a second sprocketed magnetic film. The SMPTE time code is transferred from the work print to the second sprocketed magnetic film in synchronism with the master finished audio track. The master audio finished track is then transferred in synchronism to the master edited video tape with the stored SMPTE time codes being used (14) to drive the audio film and video tape in synchronism.

Procede de synchronisation d"informations audio et video ou des techniques d"images en mouvement standard peuvent etre utilisees pour former une piste audio maitresse finie synchronisee avec un signal video enregistre Une bande video standard maitresse est enregistree (12) avec un code de temps conventionnel SMPTE ou autre code identifiant chacune des images enregistrees. Le signal video et le code de temps sont transferes sur un premier film magnetique a perforation (29) qui fonctionne a des vitesses d"images en mouvement standard. Ce film sert d"impression "de travail" qui est ensuite utilisee pour produire une pluralite de pistes audio qui sont synchronisees avec les informations video apparaissant sur l"impression de travail. Ensuite, les pistes audio sont melangees pour former une piste audio maitresse finie sur un second film magnetique a perforations. Le code de temps SMPTE est transfere de l"epreuve de travail sur le second film magnetique a perforation en synchronisme avec la piste audio maitresse finie. La piste audio maitresse finie est ensuite transferee en synchronisme sur la bande video maitresse, les codes de temps stockes SMPTE etant utilises (14) pour entrainer le film audio et la bande video en synchronisme.
