You can use Ai video clip and turn into FBX 3D motion

Using Move.Ai. You can create your own motions for use with Iclone. The motion I created was from Hailuo.Ai. I prompted in image to video of a woman doing chin ups. Took that video to Move.Ai and it converted to FBX and I converted using 3DXchange 7. It needs some more cleanup work.
