In most cases, film slates provide basic information about the scene that follows. In our military holdings, the slates tell us the unit, who the cameraman is, and the film’s subject. Sometimes the camera model is identified and the location and date are included.
They usually look like this, an example taken from reel 8 of the unedited footage for Training During Combat:
Slates are meant to be functional and pass by quickly. In fact, we usually barely notice them at all.
Last week was an exception. After spending a good chunk of time transferring a researcher request that consisted of half-hour long reels of silent unedited footage of Vietnam-era river patrol boats (also called PBRs for their official name, “Patrol Boat, River“), I came across this slate:
I think I can safely say that in all the hours of unedited footage I’ve inspected or transferred, I have never before seen a shark boat. This slate serves as a reminder that when dealing with moving images, even the most ordinary aspect can contain extraordinary detail. Don’t blink or you might miss it!
Love it!!! One of the main reasons filmmakers used slates was to sync the sound and the picture, and that’s still one of its uses. That’s why they clack. https://en.wikipedia.org/wiki/Clapperboard
Thanks!
Having a point of reference in order to synchronize the sound and picture is definitely important. Most of our unedited footage is silent and doesn’t have clapperboards. I can think of some cases where I’ve seen them in the motion picture holdings, though. We recently had a bunch of astronaut interviews from the 1960s come through that all had clapperboards in order to establish the sync.
