This invention relates to sound pictures and particularly to a composite sound record, and has for-one object the production of a .sound film having two photographic 5 sound records superimposed on the film to form one com osite sound record.
Another ob ect of this invention is the addition of a musical accompaniment to a synchronized s h film.
In the soun picture art, it is sometimes necessary to have the sound record made up of two sound records taken at different times; For example, it may be desired to have a musical accom animent for a speech or to fill in periods in which there is no h.- It is not practical to have the music recorded at the same time as the speech, due
to the difiiculty and expense of having the musicians present in all of the locations in which the action is filmed. If the sound film, for example, is a newsreel of some important event, it would be impossible to have the musicians present, yet there might be comparatively long periods of action without p 1 One method at present in use is to make a print of the sound film and project the picture, reproducing the speech through the regular equipment. A musical accompani ment is played in synchronism with the action and the combined sound of the reproduced speech and the music recorded. A sound filmis then made from the action film and the combined sound record. This method, however, will result in a serious degradation of tone quality of the speech due to the accumulative errors of reproduction.
Another method heretofore suggested is to have separate sound records on the two margins of the film, but this method requires two separate devices for changing the record into sound and unduly reduces the space on is made from the action negative and profilm, to add to the artistic appeal of the film bled in the desired order. A positive 'film' printed superimposed on the speech, the film developed, and printed, giving a commercial negative filmhaving action pictures and a synchronized composite speech and music sound record. i
In the drawing which shows one embodiment of this invention,
Fig. 1 represents a portion of the negative picture film; 1
Fig. 2 represents a. portion of the speech record on negative film;
Fig.3 represents a positive print of the picture film;
(Fig. 4 represents a portion of the music recor v Fig. 5 shows a positive print of the picture film-combined with the speech record;
Fig. 6 shows the film of Fig. 5 with a music record superimposed on the speech record.
In the production of a sound picture film in accordance with this invention, the action is filmed in the usual manner and a synchronized record made of the accompanying speech. The negative films of the action and speech, which may be on the same or separate films, are then cut and edited, the final form having corresponding portions of the films'in corresponding order. In Fig. 1, the final form of the picture film negative has been diagrammatically represented. In Fig. 2 the corresponding final form of the speech record negative has been represented, though it will be obvious that both these negatives may be combined on one film. The picture film negative is then printed, and in F ig. 3 the resulting positive film is diagrammatically represented. The speech record may be printed also on this positive though it is not required for the carryingout of this invention. The picture film positive represented in Fig. 3 is then projected in a room having suitable acoustic properties and in the presence of musicians, whoplaysuitable music to accompany the action. A photographic soundrecord of the music is made, the. movei in a sound picture projector, to project picment of this sound record film being syn-r chronized with the movement of the picture film projecting the action. This negative sound record film of the music is represented in Fig. 4,.
The picture film negative of the action 1 is then printed, and on the same positive film the sound record 03'": the speech is print-= ed, producin the positive film re resented in Fig, 5.. This positive film is again passed through the printing machine, and the sound record of the music printed, superimposed on the sound recordor" the speech, to form a composite sound record The positive film is then developed, and will show pictures of the action, accompanied by a composite sound record of both the speech and the music, synchronized with the action, as represented in Fig. 6.
- The positive film Fig, 6 may then be used tures of the action, The sound record is reproduced by well known means to give speech synchronized with the action, and a musical accompaniment also synchronized with the action.
To produce duplicates of-the positive film Fig. 6,'the positive film is printed in the usual manner to make a negative film from which positive duplicates may be printed,
What is claimed is:
1. A photographic sound record comprising a composite photographic real image developed from a latent image forming a complete record of a sound and a second latent printing one sound record on a sensitive film then printing a second sound record on the same film superimposed on the first print to form one composite sound record and developing the film.
ly making a negative film record of speech synchronized with the action, making a pos itive print of said action negative, projecting said positive print, making a negative film record of music played in synchronism with the projection of said positive print, printing imposed on the print of said speech negative and developing said positive film.
In witness whereof, I hereunto subscribe my name this 31st day of May, 1929.
