What AI is used to create these Videos?

I recently saw several videos about Boxing Memes, It seems like it's done with AI,

EG: The boxer gets punched and he plays piano or rides a motorcycle etc,

I have been away from AI since last 5 months, and it seems like you can't blink, Because the new things that AI can do each day are surprising.

If any one who is keeping up with AI knows about how these are done. Share

Thanks in advance

For anyone curious, these AI-generated videos are typically made with a combination of deep learning models, motion capture technology, and video editing software, all of which allow for these surprising and creative transformations!

I think, you can try with this one too

Its video generator they take image from last scene and write prompt , then edit the two video original and ai

If you could publish an example of this kind of video it would be easier to answer
