Long before DTS, magnetic striped 16mm films were available. The quality was quite a bit better than the optical. The speed of 16mm film is slightly over 7 and 1/4 inches per second. Home mag tape at 7.5 inches per second had great quality. The mag medium was never really successful (except in Scopitone machines). I guess the striping and recording process was just too expensive.
Probably with today's technology, classic 1.33:1 films would look quite good with a three chip DLP projector playing a DVD. The quality would probably exceed that of 16mm, since scratching, splices, and perf damage seem endemic on 16mm library prints.
The single perf design of 16mm is really a great flaw and an intermittent (rather than a pull-down claw) machine is almost imperative. Since, duplication is relatively cheap, many films are only available as poor dupes. The DVDs are generally remastered from original elements and are consequently sharper. Another interesting sidenote. 16mm was always on saftey film since 1923. I believe that safety film was invented in 1907. Nitrate was used for 35mm commercially until 1949. The industry rejected acetate because the cost was 1/2 cent per foot more. (The look of nitrate vs acetate is probably the subject of another thread). Aside from that issue, imagine the number of films that would not have been lost due to nitrate decomposition. Vinegar syndrome of acetate is less certain (I have 16mm prints from the 1920s in great condition -- no VS).
The "History of Kodak" says: [Safety film] produced acceptable images, but it broke very easily and the film cement used for splicing breaks was not effective on the acetate base. Added to these problems was the fact that the new stock cost one-half cent per foot more than nitrate film, a considerable amount of money to the cost-conscious producers of motion-picture entertainment. Eastman had hoped slowly to phase out the production of nitrocellulose stock, but so little acetate film was used that although Kodak continued to offer moviemakers both kinds of film, by 1911 hardly any nonflammable acetate stock was being manufactured."

quote: Edward Jurich I was told of a bad nitrate fire in a theater in Chicago by an operator some years ago. Guy running a cartoon show with many nitrate prints had stacked the reels on the floor, probably didn't have anyplace else to put them. Film breaks on a cartoon, he sees fire in head and opens top magazine to see if reel is burning. With magazine door open fire jumps around fire rollers and sets reel on fire. He then pulls reel out of magazine and tosses across room, right into pile of nitrate cartoons staked on floor. I know of a collector who had a nitrate fire and only lost a couple feet in the head. The fire rollers stopped the fire from reaching the reels.
I had no idea that Basil Fawlty was employed as a projectionist in Chicago!
I have no way of telling if this story is true; there are probably more 'tales' involving nitrate than anything else in the film world. If it is true, then:
quote: Edward Jurich Guy running a cartoon show with many nitrate prints had stacked the reels on the floor
Well, that should be enough to get him instantly sacked, at least it would have been if it had happened in this country.
quote: Edward Jurich he sees fire in head and opens top magazine to see if reel is burning
Unwise.
quote: Edward Jurich With magazine door open fire jumps around fire rollers and sets reel on fire.
There was a good reason for having the spools in spool boxes (magazines), with *closed* doors.
quote: Edward Jurich He then pulls reel out of magazine and tosses across room, right into pile of nitrate cartoons staked on floor.
Is this serious?
I've handled plenty of nitrate, and projected it a couple of times, though not in a public cinema.

Oh, the anecdotes get much worse. Some can be found in this book ('This Film is Dangerous').
John - I heard somewhere that Eastman decided on 16mm specifically because it could not be made simply by slitting 35mm down the middle, therefore reducing the risk of 'unauthorised' 16mm nitrate being manufactured by small-scale manufacturers buying unperforated 35mm nitrate base in bulk. As far as I know, the USSR and China were the only countries to have experimented with 16mm nitrate. I once had delivered a 16mm print of The Green River Flows East at the NFT, which had been sitting in the BBC archives, for a routine show. I thought I sniffed the telltale 'mothball' nitrate smell from it, and called in my chief. He thought I must have been off my trolley, because of course no-one made any 16mm nitrate. I persuaded him to put my mind at rest by cutting a foot or so off the head spacing of one of the reels and then igniting it. The resulting flare-up convinced us both! Sadly, the show had to be cancelled, but rather that than being kebabbed in the projection box.

quote: Steve Guttag An odd format that seems more popular than 16mm scope is 16mm 1.85 where the 1.85:1 ratio is hard matted on the 16mm frame.
Very common here in the '70s. few 16mm machines have either replacable aperture plates, or adjustable apertures, Bell and Howell being the main exception, though the movable blades were a long way back from the emulsion plane. Hard-matting was necessary to get the picture shown at the correct ratio.
I was never very keen on this; the 16mm frame is small enough, without masking off about a third of it. I saw a demonstration of 16mm 1.85 with a 1.5 ratio anamorphic lens, which used almost the full frame, just slight masking being needed at the sides. I think this was a much better way to do it.
16mm scope prints were rare, I doubt if I've ever run more than half a dozen. Most scope films that I've run on 16mm were either hard-matted to 2.35 within the 1.33 frame, or cropped to about 1.66-1.85, and hard-matted to this ratio. Neither option being very satisfactory.
