Description

Nachsynchronisierungsverfahren für Bildtonfilme, bei dem den die Synchronerzeugung der Töne veranlassenden Leitmitteln ein Vorsignal vorausgeht Die Erfindung bezieht sich auf Nachsynchronisierungsverfahren für Bildtonfilme, bei denen den die Synchronerzeugung derTöne veranlassenden Leitmitteln ein Vorsignal vorausgeht. Bei den bekannten Verfahren wurden als Vorsignale andere Leitmittel verwendet als die, die zur Synchronerzeugung selbst dienen, z. B. wurden auf dem Bildfilm für die Aufnahme vor dem Teil, der die Bilder trägt, sichtbare Signale angeordnet, auf Grund deren die bekannte Synchronklappe betätigt wird. Die Verschiedenheit des Vorsignals und des die Synchronerzeugung der Töne veranlassenden Impulses erschwert das Arbeiten, da sich Ohr und Auge auf verschiedene Impulse einstellen müssen und daher schwer reagieren.Post-synchronization method for picture-sound films, in which the synchronous generation the control means causing the tones is preceded by a distant signal. The invention relates on post-synchronization methods for picture-sound films, in which the synchronous generation the routing means causing the tones is preceded by a distant signal. With the known methods other means of guidance than those used for synchronous generation were used as distant signals serve yourself, e.g. B. were on the pictorial film for recording before the part that which carries the images, arranged visible signals, on the basis of which the well-known synchro-flap is operated. The difference between the distant signal and the synchronous generation the impulse that causes the sounds makes work more difficult, since the ears and eyes are open have to set different impulses and therefore react difficultly.

Gemäß der Erfindung sollen als Vorsignal dieselben Leitmittel dienen wie die die Synchronerzeugung selbst veranlassenden Leitmittel. Hierdurch werden die beiden Leitmittel leicht erfaßbar und das Arbeiten bei der Nachsynchronisierung erleichtert. Zweckmäßigerweise können zwei inhaltsgleiche Bildfilme vorgeführt werden, deren einer als Vorsignal um eine Bildhöhe gegenüber dem anderen vorauseilt. Auf diese Weise hat z. B. ein Kapellmeister, der für eine bestimmte Szene die Musik dirigieren soll, den Vorteil, bereits durch Ablauf des ersten Filmstreifens auf die Einsatzstelle aufmerksam gemacht zu werden, und kann sich dadurch viel besser auf das kurz darauffolgende, für den Einsatz maßgebende gleiche Bild im zweiten Film vorbereiten. Dasselbe gilt für jede andere mechanische oder sonstige Erzeugung von Tönen oder Geräuschen, deren Synchronaufnahme verlangt wird.According to the invention, the same guide means should serve as the distant signal like the control means which cause the synchronous generation itself. This will be the two control means are easy to grasp and the work with the post-synchronization relieved. Appropriately, two image films with the same content can be shown, one of which, as a distant signal, is one picture height ahead of the other. on this way has z. B. a bandmaster who plays the music for a certain scene should conduct, the advantage of already running through the first film strip the place of work to be made aware, and can be much better as a result to the same picture in the second, which is decisive for the application shortly afterwards Prepare the film. The same applies to any other mechanical or other production of tones or noises which synchronous recording is required.
