Sound Projector WILLI M • Showing method of threading sound track and picture films together in projector for trial run. Solid arrows indicate sound track A; picture is indicated by B. Most all modern sound projectors will transport two films safely. I FTER YOUR sound film has been /i completely edited and synchronized, l\ it is important to have a reliable means of checking the sync before sending the sound and picture films to the lab for combined printing. This can be done in several ways. The best and easiest, of course, is to use a 16mm. Moviola. This is a device which in corporates a small viewing screen and a sound head. The picture film is threaded in the viewer and the sound film is threaded over the sound drum. A small amplifier and speaker provide the sound. The entire unit can usually be mounted on the editing table. For the average amateur, the Moviola holds one disadvantage, that is, cost. The equipment is rather expensive, running in the neighborhood of a $1,000. Perhaps the more practical method for the amateur is to use a sound projector. The average sound projector can be adapted to run both the picture and sound films at the same time. The procedure is as follows: The picture film is threaded in the projector at the point where it leaves the gate. Film will either pass over another sprocket or will go directly to an auxiliary takeup reel, as shown in photos. It is advisable to • Showing use of auixilary feed and takeup reels when separate sound track is run with picture film through projector. Reel A Is takeup for sound film; B is supply reel for picture film; auxiliary supply reel for sound film is shown at C; and auxiliary takeup reel at D at extreme right. J . N M N N have the picture film pass over the sprocket immediately following gate, then the film will go to the auxiliary takeup. The sound film, placed on an auxiliary supply spool, is then threaded over the same sprocket as the picture film after it leaves the gate. The sound film is threaded over the sound drum in the normal manner and is taken up on usual projector takeup reel. The illustration shows this threading method with a Bell and Howell projector. By a little experimenting almost any sound projector can be adapted to run the two films. Some workers prefer to fit up the projector itself with additional supply and takeup. However, it is necessary to have a spring belt to provide takeup, but such a change in a projector is not beyond the capabilities of a good machinist. After you have determined the best method of running the two films in your own particular projector, you are ready to check the synchronism of the sound and picture films. If the film has already been advanced and the holes punched at the sound advance marks, as outlined last month, then thread your sound film in the projector as you would normally thread any sound film. The sync mark should be placed in the projector gate. Then remove the sound film, up to the point where it passes over the sound drum. The sound reel is then placed on the auxiliary supply spindle. The picture film is then threaded, with the picture sync mark in the gate, and the film goes to the auxiliary takeup, as previously explained. • CoiifimirJ oti Pa,?? 529 MIDSUMMER HARVEST scene at right is rare camera study by western pictorialist, Ross Madden, who offers it as timely title background for Home Movies' readers. A novel treatment of these photo backgrounds is to shoot picture first, then superimpose title text by double exposure. Be sure to arrange title letters on black velvet or other similar material. Shoot at distance of 30 inches, using 1 '/4 diopter cuxiliary lens. 484
