As you might know, MAPPA Studios produced the last season of Attack on Titan. Part 2 of the final season is going to air on January 2022, but from this interview, it looks like they are still finishing the animation as we speak.

I find it rather odd, given that the live panel I posted back some months ago mentioned their production notes as "finished". This would be logic since Jujutsu Kaisen, Chainman and other productions were already scheduled while AOT S04 P1 was being finished.
I did not produced the above video. I found it through the animator's network I'm usually checking. Please note that this video can be taken down at any moment, so please watch it, as it has some important methodology that can help you produce better animations in an anime studio like MAPPA.
