In cinematography, match moving is a visual effects technology to allow the insertion of virtual objects into real footage with the correct position, scale, orientation and motion in relation to the photographed objects in the scene.
This is really nice work by Druskq again. The footage is essentially tracked and rebuilt into a 3D environment using a powerful piece of match moving software called 'Boujou'. It allows you to completely duplicate both camera movement and depth, and to also composit CG-elements (the light beams in this instance) into the scene.
For example, points closer to the camera move faster, relative to points further away, and based on this difference in speed, the program will be able to derive the relative distance. You end up with a scene full of tracked points (or Nulls), and you'll be able to use these to reference where any CG-elements have been positioned.
The light strokes were actually created in After Effects - moving a light emitter and particular through 3D space. I'm going to run with this over reading week, and see if i can get into a decent position with it for when we get back.
