What software exists for taking notes on videos? (e.g. lectures, political speeches, video games, or even music videos.) Having a clean and easy way to annotate video content according to timestamp would have lots of educational value. I've found these two sites which seem to do the job, but they seem clunky or non-intuitive:

Can anyone suggest other options?
