When I was at primary school, our art teacher invited a cartoonist who told us that he had to create 12 images per second, i.e. between 15,000 and 16,000 images for a 22 minute episode. But this is an approximation, as the number can increase depending on the quality of the images. However, in the old days, we did things by hand, but I think now, with new processes and AI, things are much easier.
