One of Blender's strengths is the tight integration of modeling, rendering, and compositing. Blender 2.61 has made this integration even tighter with the new camera-tracking module, the MovieClipEditor. Importing footage, tracking and solving the camera motion, rendering, and compositing can now all be done in one smooth workflow, all inside Blender.
