Rotoscope is like when people paint over film frames like they are photos.
It looks like maybe you used some kind of AI art painting program on a photo -- I'd guess. Or maybe you commissioned someone, or maybe you painted it yourself.
Rotoscope is like if you took a video of yourself, and just painted or used an AI art program for each frame, then linked it together in animated sequence.
Like a GIF would be the easiest way.
Kind of a neat idea, actually.
