Adobe After Effects - Loop-Pro
Do you want to create a GIF that loops perfectly? Loop-Pro was designed with looping wiggles and keyframes in mind to help you take the guesswork out of seamless loops. With the Loop-Pro preset, you don't need to set a single keyframe.
Even if you aren't making a looping video, Loop-Pro provides the user a unified interface for creating great looking wiggles that allow you to customize the effect without touching a single line of code.
