Oh, I try never to have a video at all. It's slow, hard to search, hard to go back, hard to jump useless stuff, hard to comprehend, and hard to interrupt.
Yet, the GP's point stand. If you see the video of a person starting a python project, it won't be missing the `virtualenv` parameters that he would omit in the text tutorial.
Video also beats anything else (except physical presence) on discovering what somebody did to cause a bug.
