As you start thinking about your video and podcast projects, I thought I would post a couple tutorials about making videos from the Vimeo Video School. There are a lot more to be found if you follow the link, but here are a couple embedded right here on the blog that I think I particularly important. The first one includes some shooting basics and the second one discusses general video editing. Depending on which piece of software you are using for the editing, you can watch a more detailed video about using Microsoft Movie Maker (on a PC) or iMovie (on a Mac).
Video 101: Editing Basics from Vimeo Staff on Vimeo.
It seems to be a little more advanced, but Lifehacker also has a series of tutorials about video editing.
Finally, there is also a page on the UBC Wiki about video production that includes tutorials and a whole bunch of links to other resources.
Happy shooting!
