Before we move to part 2 where we use the compositor like in the video above I always like to brush up on my basics. The two videos below demonstrate the user interface, how to add files and other things. These videos aren't by me but from part 2 and on out I'll be doing the tutorial videos.
For people who want a more USER FRIENDLY video editor should check out Openshot.
OpenShot 1.2 Highlights from Jonathan Thomas on Vimeo.
Simple. Powerful.OpenShot Video Editor is a free, open-source video editor for Linux licensed under the GPL version 3.0.
OpenShot can take your videos, photos, and music files and help you create the film you have always dreamed of. Easily add sub-titles, transitions, and effects, and then export your film to DVD, YouTube, Vimeo, Xbox 360, and many other common formats.
Another honorable mention for Open Source Video Editor would be KdenLive. Kden's usability is between cinelerra and openshot, as such it is powerful if patience is applied, but can also be quick and easy to use. kde-files.org has transition images and other extras worth checking out.
