Marked start point in an audio file enabling precise location access during the cut.
Technical Details
Cues are synchronized using SMPTE timecode on a 1/24-second basis (at 24fps) and are typically composed with a pre-roll of 2-8 bars. Numbering follows a systematic reel structure: "1M1" denotes the first music cue in Reel 1. Modern Digital Audio Workstations (DAWs) like Pro Tools work with cue lists that include start TC, end TC, fade-in/out points, and hit points (exact sync moments). Streamers – visual countdown aids with 3-2-1 markers – prepare musicians for cue entries.
Distinctions are made between Music Cues (orchestral or electronic compositions), Source Cues (diegetic music from within the film's world), and Effects Cues (atmospheric soundscapes without melodic structure).
History & Development
The cue system originated in 1927 with the transition to sound film, when Warner Bros. first cataloged synchronized music-to-picture assignments for "The Jazz Singer." In 1933, Max Steiner established the cue sheet system at RKO for "King Kong," which is still valid today, with 47 individually numbered cues. In 1950, the major studios introduced standardized cue lengths of 10 feet of film (6.67 seconds at 24fps) as the smallest unit.
Digitalization brought more precise synchronization in 1985 with MIDI timecode. Since 2010, cloud-based systems like SessionWire have enabled real-time collaboration between geographically separated composers and orchestras.
Practical Application in Film
John Williams structured the 134-minute "Star Wars" score (1977) into 21 main cues, with Cue "1M1 Main Title" lasting exactly 5:20 minutes. For "Inception" (2010), Hans Zimmer developed the modular cue concept: base cues in various tempos that can be adjusted according to the final cut.
The spotting process defines cue placement: the director and composer mark entry points in the rough cut, typically 25-40 cues per 90-minute film. Modern temp tracking uses existing cues as placeholders for the final composition.
Comparison & Alternatives
Cues differ from Stings (short accents under 10 seconds) and Beds (continuous background music without a defined endpoint). Bumpers – 2-5 second transition elements – function as mini-cues between scenes.
Adaptive Music Engines in video games replace static cues with algorithmically driven, endless variations. Streaming platforms favor longer cues (3-6 minutes) over the TV-typical 30-90 second segmentation, as commercial breaks are eliminated.
