Nice diagrams to explain what's going on. The main thing I'd suggest if you're changing it is on the hold time violation diagram (around 3m15) it'd be worth adding some headings to make it clearer that those are "good" and "bad" timing diagrams (or maybe "no clock2 skew" / "clock2 skew"). I also feel like it'd help to do something to tie the "part of the timing diagrams that is the left flip flop" and the "part of the timing diagrams that is the right flip flop" more directly to the actual flip flop diagram. Not entirely sure what's best there. Maybe having the pair of flip flops arranged vertically (instead of horizontally), at the same spacing as the timing diagram, and align "clock1" / "clock2" on the flip flops with the "clock1" / "clock2" on the timing diagrams? (The video also seemed to end very suddenly after the H clock tree explanation; but I'm guessing maybe you intended to add more explanation after that in the final version?)

Thanks for the feedback! Re the sudden ending, Yes I'm going to edit this into my interview with @mkk but wanted some feedback first.
