Time remapping is a feature in After Effects that enables users to modify the timing of layers and clips, allowing for greater control over animation and video playback speed. This technique allows you to stretch, compress, or manipulate the temporal aspect of a video or animation layer, effectively letting you adjust when a layer appears or how long it remains visible.
Using time remapping, you can create slow-motion effects by extending the duration of clips or speed them up by compressing their timeline. It also allows for intricate keyframe animation, where you can adjust the timing of different effects and transitions to create a more dynamic visual experience.
The other functionalities mentioned, such as layer styles, frame interpolation, and rendering, serve different purposes. Layer styles focus on the appearance of layers rather than their timing. Frame interpolation relates to improving the smoothness of animations by generating intermediate frames, but it doesn’t change the timing per se. Rendering is the process of exporting your project into a final output format, which also does not involve manipulating timing within the composition.
