Hi, I have seen this video in this website: https://www.tickling.ai. I asked the author how he made them and he wrote to me that he uses 3D human models to which he then adds animations. Then he transforms them either into cartoon format or into hyper-realistic animations in Unreal Engine. He also told me that the complete videos are on sale on Clip4sale in the TicklingAI Store, you can see the previews on the website www.tickling.ai. I purchased one in hyper realistic format and they are truly impressive in terms of realism. Women are all very beautiful.
