Vinegar syndrome camphor w/ no bend cooking stains.



Film was mounted on 2 x 1600' reels and printed on Eastman color film stock. No Vinegar Syndrome. Print has leaders and countdowns. Some people want to know, "how long is this film"? Well that's an interesting question. Sound films run at 24 frames per second, but silent films were often shot at a slower rate, 18 frames per second. This means that while a 400' reel of sound movies runs about 11 minutes long, a similar 400' reel of silent movies will run 14.5 minutes or so if projected at the proper speed. Similarly, a 100' reel of film will run three to four minutes. People ask about vinegar odor and/or the "mothball" smell. The mothball or camphor smell is a residue left over from camphor oil which was recommended by Kodak to keep films supple. Back in the 20s and 30s Kodascope film cans actually had a paper filter built into them which could be saturated with a drop of camphor oil, and it seems to have worked effectively. Camphor use on movie film was discontinued during WWII due to military use of camphor. But, a different situation is if a film is emitting a vinegar odor, that indicates it is beginning to deteriorate. Films that have light vinegar odor are almost always projectable and can be telecined. Films with heavier levels of odor or full blown "vinegar syndrome" -- an extreme version of the problem - require care, treatment with chemicals or molecular sieves, or other handling or repair before transfer. In some extreme cases they may not be salvageable. That was not the case with this transfer, thankful;ly (intended typo in order to play with my new mechanical loud glow keyboard).
