Audio Fade Out

Applies a fade-out effect to the audio track at the end of the video.

video-audio-fade-out accepts a float value in seconds between 0.0 and 1000.0. The audio gradually decreases from full volume to silence over the specified duration before the video ends.

For example, video-audio-fade-out=3 fades the audio out over the final 3 seconds of the video.

Use video-audio-fade-in to apply a corresponding fade-in at the start of the video.
