Audio/Video Glossary - FadingIn video, fading deliberately diminishes the video picture until it becomes totally black. Fading a video image is often used as an artistic tool in video productions. For example, gradually replacing one scene with another by cross fading*.
In audio, fading decreases the level of the signal until it is no longer heard. Audio fading is often used together with video fading resulting in the sound and image disappearing simultaneously.
