a dark screen that gradually brightens as a shot appears.

The film is shot at less than 24 frames per second so that when it is projected at normal speed, action appears to move much faster. (A slow motion is achieved when film is shot faster than 24 frames and projected at normal speed.) Also called accelerated motion.

field or location Mixer - A mixer that is used on site at the location of a film, tv or radio production that allows the location sound supervisor to both connect together and then mix the sound sources from different sources on a film or TV location, including presenters, actors and location sound sources.

The mixer is usually much smaller than mixers used in recording studios and will either be a table top mixer with 8-12 channel inputs (often mounted on a rack of sound equipment) or worn over the shoulder by the location sound supervisor.

Shoulder worn location mixers usually have fewer inputs - between 2 to 6 inputs)

In both cases the OUTPUT of the mixer - which can be 2,3,4 or more sound signals) is sent EITHER back into the main camera (which can often record 2,4 or 8 tracks of audio at the same time) or a portable sound recording device.

lighting from a source less bright than the key light, used to soften deep shadows and illuminate areas not covered by key light. Also called filler light. See three-point lighting.
