Are there any helpful calculus videos?

1.     a.        http://www.midnighttutor.com/math_tutor_online.php

                                                               i.      Has all sorts of videos (they even say you can email them questions and it’s quite possible they will get back to you within a day)(+ chem. Videos if your taking chem.)

                                                             ii.      There’s pre-calc video’s (more review)

                                                            iii.      There’s videos for limits and derivatives and everything we’ve learned in Calc 1

                                                           iv.      There are videos for what I assume  would be helpful in calc 2 and 3

                                                             v.      The guy who does the videos has a strong voice, and isn’t creepy

                                                           vi.      He uses a white board, in which everything is visible

                                                          vii.      Videos range from around 15min to 1 hour

                                                        viii.      Kind of long introductions

b.       http://www.khanacademy.org/

                                                               i.      Has many, many videos on everything calculus

                                                             ii.      Has videos for specific rules, such as (chain rule, more chain rule, and quotient rule)

                                                            iii.      There are videos for future calculus

                                                           iv.      There are videos for everything from algebra review to pre calc review

                                                             v.      Done on a computer screen with voice over

                                                           vi.      Easy to understand

                                                          vii.      Easy to find a the topic you’re looking for

c.        http://www.brightstorm.com/math/calculus

                                                               i.      Has a good amount of videos to pick from

                                                             ii.      Is colorful and easy to watch

                                                            iii.      The selection of videos is easy to watch

                                                           iv.      The way things are explained make sense, but is not my preferred way of learning. It may be to others

                                                             v.      Also has pre-calc videos

Conclusion

Out of the three sites I like (b.) the best. Although I did like that I could watch someone actually doing the problems in the first one the videos seemed to be a little drawn out and the sections were not cut up as much as (b.) and (c.). (b.) used color, they wrote out all the steps, had example, and explained concepts.
