The video editing is also fine. If such minor issues break your rhythm, you might need to rethink your approach to the lessons.
Given that there are still thousands of students in the class and enjoying it, it didn't "fail" at all.
Video editing in AI class is against the knowledge that we have learned in 100+ years of movie editing. Cutting 1-2 seconds but keeping the same scene gives a jarring experience.
They cut out a few seconds so that you don't need to watch Norvig or Thrun to finish writing of a word or sentence, but that's saving time in the wrong place in my opinion. If you watch Khan Academy or ML class, those 1-2 seconds give a natural pause, that you can use to think about the subject.
I've nothing against the pen and paper approach, although occlusion is sometimes a problem. Based on my experience with Khan, AI and ML classes drawing by hand is the essential thing, is it less important if it's done electronically or by pen and paper.
Anyway, my main point is that execution of e.g. Khan Academy and ML class are better than AI class, and I'd personally prefer that inspiration for new online education courses is taken from them instead of AI class approach.
On the other hand, the videos themselves are actually better (I love the pen-and-paper approach), and there's a lot more small questions within lectures, which helps keeping my ADD in check.
