If you want to learn more about video editing it does not hurt to have as much information as possible. Videomaker Magazine has a variety of free e-mail news letters that contain tips on how to work with video.
I just subscribed to the editing newsletter and got a bonus pdf of Videography Essentials. I've been a reader of the magazines on and off for a long time so I know the style of writing and instruction. They do deliver on giving solid information.
In addition to free content there are tutorial pdfs for sale, webinars and workshops that you can attend. If you are a self-directed learner of video this is a good web site to spend some time exploring.
