What CEB 4D human is?

The CEB 4d humans addon  is a tool that can make you animation work much faster by using a single video as input and export a very good animation that can be used in many ways:

  • create an animation reference for you to create your own animation, understanding better how the body moves
  • you can use it with he smoothing tools to fix th jitter that usually comes with markesless mocap solution
  • you can select key poses (and erase everything else) to use as the first pass on your animation project

What you can do with CEB 4D Humans:

  • you can easily create animations using almost any video with one or more people
  • use the provided tools to remove jitter 
  • use the foot height to lock the foot on the Z axis (in case you have some unexpected results where the body goes away from the floor when it shouldn't)

What you can't do:

  • you can't have finger tracking
  • you can't have face tracking

Computer Specs needed:

Total 15gb of free space on the hard drive which is:

10gb free on windows user folder (usually drive C)

5gb free for venv data (any drive you select)

A CUDA compatible card with 6gb (users reported that it works) to run the full process on your pc.

If you dont have CUDA card or less then 6gb of memory you can run animation generation on google colab and import it on the addon to finalize and import the data.

How to use the animation on your own character

Tutorial using google Colab + CEB 4D Humans

link to official 4d humans google colab was not working in October 2023, try this colab instead:



This tools uses SmoothNet ( to clean the data created with CEB 4D Humans.

this smooth will only work with animation created with CEB 4d Humans or the google colab one.

Smooth 2 "j4ck (Giacomo Spaconi) Method"

this smooth tool can make the animation much better than the raw data, and this tool can be used on other animtions, not only in CEB 4d Humans ones.

Foot height lock

This tool can help to make the animation not to fly around. Select the place where it should start to be locked to the floor, and when it should stop. this selection is necessary because you can have some action where the character jumps

Pack of free animations

This product also comes with a pack with several raw animations created with CEB 4d humans, that can be loaded loaded in blender using the addon.

Expect more animations to come in the future.
