Comments.Text: You're suggesting to reverse the animation and put it back to back with the forward animation. This solution doesn't look so good because the point where the animation switches from running forwards to running backwards is very noticeable and jerky, in contrast to the smooth and subtle forward animation

Comments.Text: Yes. It works *technically* but it doesn't work *visually*. It's because the animation itself flips direction. So for example a branch that moves clockwise starts suddenly to move counterclockwise in the same velocity and that *feels* unnatural

  In order to get a fluid and seamless loop, it's key to **enable Cycle Evolution** and **move the last keyframe 1 frame beyond the end** of the composition.
  
  1. Add the **Turbulent Displace** Effect onto the footage
  2. Open up **Evolution Options**
  3. Enable **Cycle Evolution**
  4. Go to the **first frame** in the timeline
  5. Click on the stop watch of the **Evolution value**:
  
     ![enter image description here](https://i.sstatic.net/0nxoM.png)
  6. Go to the **last frame** in the timeline and set the **Evolution Times** value to `1x`, this is equal to 360 degree (one revolution)
  7. Move the second keyframe **1 frame beyond the end** of the composition:
  
     ![enter image description here](https://i.sstatic.net/47sEr.jpg)
  
  ### Example
  
  ![enter image description here](https://i.sstatic.net/jsS5Z.gif)
  
  * Composition length: `51` frames
  * First evolution keyframe value: `0x` at frame `0`
  * Second evolution keyframe value: `1x` at frame `51`
  
  **Note:** This seems to work with all fractal effects.
