It’s image generation just like the prototypes that converted your drawings into “realistic” image are. It’s clearly completely redrawing the frame into a new one using the output of the game as a basis.

It’s not done 60+ times per second on phones. And I’m not even sure all this processing is done locally in the first place on Instagram and such.

Sounds nice, I personally like taking time to cook good food. Can we have the recipe?
