One of the features of Blender that is not directly related to 3d modeling, rendering or animation that impress most people in my classes is the video sequence editor. A lot of people, specially those users from 3ds Max, Maya and other softwares are used to work with a non-linear editor to edit their animations, like Adobe Premiere. When I mention that Blender has his own internal video editor they simply love it!
For those of you that never had the opportunity to use the video sequence editor, I found a great tutorial that shows how to use transform strips in the sequence editor. This might give you a good starting point to use the video sequence editor in Blender. This tutorial was created by David Mcsween.
Cool,
this is actually not about transforming like I think but about After Effects-like-adjustment layers and using HD proxies for smoother playback.
