Time remapping in After Effects allows you to manipulate the speed and duration of a layer or composition by adding keyframes to the timeline.
When you enable time remapping for a layer, two keyframes are added to the timeline: one at the beginning of the layer and one at the end. You can then adjust the position of these keyframes to change the speed and duration of the layer.
In the case of creating a looping video, you can use time remapping to repeat a specific section of the video by moving the second keyframe to the beginning of the video. This will cause the video to play from the beginning again after reaching the end.
Keep in mind that you can also use time remapping to create slow motion or fast motion effects, as well as other creative uses like creating a freeze frame or stuttering effect.
If you want to create a looping video using After Effects, follow these steps:
- Import the video file into the software. This can be done by going to File > Import > File… in the top menu.
- Once the video file has been imported, you will need to drag it from the “Project” panel to the “Composition” panel in order to add it to your project.
- Next, you will need to select the video layer in the “Composition” panel and enable time remapping by going to the “Layer” menu and selecting “Time > Enable Time Remapping”. This will add two keyframes to the beginning and end of the video.
- To create the loop, you will need to move the second keyframe to the beginning of the video by clicking and dragging it to the left.
- To preview the loop, you can press the spacebar to play the video.
- If everything looks good, you can then proceed to render the video by going to Composition > Add to Render Queue in the top menu.
- From there, you can choose your desired output settings and click “Render” in the “Render Queue” panel.
