What describes a single image in a motion picture sequence?

• A. Frame
• B. Diegetic music
• C. EDL
• D. Dub

Answer: (A)

A frame is the single still image that makes up the sequence of a motion picture. A film or video is shown as many frames per second, so when these still images play in rapid succession, they create the illusion of movement. Each frame holds one moment in time with its own composition, lighting, and action, and the set of frames together forms the moving picture.

Diegetic music refers to music that exists within the film’s world and is heard by the characters. An EDL, or edit decision list, is a document editors use to outline cuts and transitions. A dub is the process of recording or replacing dialogue or other audio. Understanding that a frame is the building block of motion helps explain how film and video timing works and why frame rate matters for the smoothness of the playback.
