24 frames per second is the standard frame rate or film speed for movies shot on film. It is the number of frames or images that are projected or displayed on screen per second. Before the filmmaking industry set a standard in the silent era, many films were projected at 16 or 18 frames per second, but that rate proved to be too slow when attempting to record optical film soundtracks. 24 frames per second is occasionally shortened to "24fps" or "24p."

The second assistant camera is the crewmember responsible for writing detailed shot information on the slate and holding it in front of the camera before each shot. The slate (or clapboard) is where production keeps track of the take number and provides a "clapper" to help sync sound.

The second assistant director is the crewmember responsible for distributing and organizing all production paperwork, such as scripts and call sheets, to the correlating cast and crew. The second assistant director also helps supervise the set with the 1st AD. It is typically shortened to "2nd AD."
