It is helpful in understanding the flow of 3D animation production, but overall, it is a very disappointing lecture. The volume is different for each lecture, and it seems like they explain what they think of on the screen at that time without a lecture script.
Although it is not mentioned in the current lecture introduction, Mixamo is mainly used for rigging and animation, and then some modifications are made to complete it. However, things like breaking objects with iron balls or shark swimming motions that are mentioned in the lecture introduction are not learned. It seems less necessary for those who know Mixamo to take this course.
