on the CGCookie site, there are a few older ones (You can filter on Visual Effects, when you go to the 3 little lines on the top left > All Courses)
https://cgcookie.com/courses/compositing-a-3d-monster-into-a-live-action-scene
https://cgcookie.com/courses/compositing-transformer-vfx-in-blender
Still a lot of good information there!
