Blender is really cool in that you can mix your modes of editing between projections of that video in 3D space, 2D-based compositing, and 2D-based mixing in the VSE, all at the same time. An uber-cool idea is to use your video to texture something - a plane, or a sphere commonly, and then film that texture using the camera (orthographic or lens-based) to get all sort of very cool distortion effects. I came up with this simple but versatile rig that I use in a lot of the remaining tutorials, so set one up for yourself!

BTW, please <3 the tutorials you like, and subscribe, and contact me if there are any errata or other areas you want me to go into.
