To change the speed of a video in After Effects, you have a few options at your disposal.
These options include:
To use the Time Stretch effect in After Effects, follow these steps:
- Import your video into After Effects by going to File > Import > File
- Drag your video onto the New Composition button at the bottom of the Project panel. This will create a new composition with your video
- With the video selected in the Timeline, go to Layer > Time > Time Stretch
- In the Time Stretch effect, you can specify the amount of time you want to stretch the video.
For example, if you want to double the speed of the video, you would set the Time Stretch value to 200%. If you want to halve the speed of the video, you would set the Time Stretch value to 50%.
The Time Stretch effect is useful for quickly adjusting the speed of a video, as it provides a simple interface for setting the speed. However, it does not offer as much control as the Time Remapping feature.
