ABSTRACT
Reality is fine, but it’s not always what one wants. Sometimes one needs a captured movie to play back more quickly, more slowly, or backward, or to stop altogether. After Effects has options to Time Stretch a clip, which gives it a new constant speed, or Time Remap it, which allows the speed to change over time. The Time Stretch feature can be used to speed up or slow down video, audio, and nested comp layers. Time stretching affects any animation already applied to masks, effects, and transformations, so speed changes also apply to keyframes. If a movie layer contains audio, the audio will also be time stretched and resampled. If one does not want to time stretch the audio, before stretching duplicate the layer, then turn Audio off for the original and Video off for the duplicate. Any keyframes applied to layers inside the precomp will be adjusted accordingly, retiming the animation.
