He can prepare 20 animations per week. But the most important work is rendering, drawing graphics, according to the template set by the author. This requires computing power. And now this speed is 10 animations per week. The processing speed depends on the complexity of the animations, but I don't think this process can be greatly accelerated. It still adds the rest of the static renders, which slows down the animation processing a little, taking up the power of computers. But there are so few of them that when he finishes it, we can count on a small increase to 12-13 animations per week, no more.
I am very interested in why the work on animations has slowed down compared to Ep. 7-8 and I'm looking forward to seeing their quality.
