This is a great little short produced by the San Francisco Exploratorium interviewing experimental filmmaker (and SFMOMA projectionist) Paul Clipson about the process of exhibiting film. A solid introduction to the subject for people of any age or experience, though it’s hard not to feel elegiac while watching this—like you know this could be shown as a historical document of a lost process already…

There’s a point near the two-minute mark where Clipson pulls out a binder of notes he’s made for other projectionists about where to make reel changes. “I started making notes for the projectionists, which is just something I specifically do. Not everybody does this, or…I don’t know if anybody does it,” he admits, and then he pulls out these gorgeous sketches, more detailed storyboards than mere notes. The love for the medium, for the material itself is so evident here.

Clipson has a couple of screenings in November—one in San Francisco, the other in Paris. If you can’t make it to either, his vimeo page is always worth your time, featuring experimental shorts made in collaboration with Jefre Cantu-Ledesma, Gregg Kowalsky, and others.
