Recently Microsoft made available videos of several sessions at their latest HTML5 Web Camp in Silicon Valley.
The series covers basics of HTML5 and CSS3, plus in-depth dives into the most popular features (Canvas, SVG, audio, and video).
Even if you're already somewhat familiar with the standards, the videos gel nicely together. If you're just starting to try HTML5, these videos will serve as a free substitute for a full-fledged web camp.
Video 1: Introductions to HTML5 and CSS3
