Fade Out: gradual darkening of the image to black by reducing luminance from 100% to 0%, typically over 24 frames (1 sec) in Avid or 30 frames in Premiere Pro.
Technical Details
In digital editing systems, the fade out is realized by multiplying the RGB values with a factor between 1.0 and 0.0. Avid Media Composer uses a standard 24-frame fade out (1 second at 24fps) for this, while Adobe Premiere Pro prefers a 30-frame standard (1.25 seconds). The mathematical curve typically follows an ease-out function with the formula f(t) = 1 - (t/d)², where t represents the elapsed time and d the total duration. Variants include Fade to White and Fade to Color (transition to defined color values).
History & Development
Georges Méliès first used manual fade effects in 1896 by covering the camera lens. D.W. Griffith established the fade out as a narrative transition in 1908 in "The Adventures of Dollie." Mitchell Camera Corporation developed the first mechanical fade device for film cameras in 1917. In the 1920s, optical printers with precise fade mechanisms emerged, remaining standard until the 1990s before digital post-production replaced them.
Practical Use in Film
Akira Kurosawa used 3-second fade outs between life stages in "Ikiru" (1952). Stanley Kubrick exclusively used hard cuts in "2001: A Space Odyssey," deliberately avoiding fade outs to enhance the cool aesthetic. Modern blockbusters like Marvel productions employ 0.5-second micro-fades between action sequences. In post-production, fade outs are typically applied as the last correction layer to avoid affecting color corrections.
Comparison & Alternatives
The fade in is the technical counterpart with reversed luminance progression. Crossfades combine simultaneous fade outs and fade ins of two image sources. Hard cuts are increasingly replacing classic fade outs in contemporary productions – Christopher Nolan exclusively uses direct cuts in "Dunkirk." Digital alternatives include iris wipes and morphing masks, which allow for more complex transition geometries.
