We like to experiment here at NMA. The Obama clip you’ve just watched above was produced using a technology known as facial motion capture (or mo-cap for short.) Motion capture involves using a computer to track the movements of a series of reflective dots attached to the body, or in this case, the face.
The model, for this video President Obama, is then driven using the recorded movement of the nodes.
The following series of photos shows how the nodes are attached before the motion capture takes place.
Photo 1 shows our mo-cap model (we used an English-speaking model for this job) having the locations of the nodes drawn on his face by our mo-cap experts.
Photo 2 shows the model’s face with half the reflective nodes in position.
Photo 3 shows the model with all nodes in position. He is practicing the poses needed to record a full set of facial expressions.
Photo 4 shows the model’s face as seen by the mo-cap cameras. As the voice model reads the dialogue, the computer records the movement of the modes using in this case 10 mo-cap cameras.
The Obama model is then integrated with the recording of the node positions. The finished product is what you watched at the top of this post.
Hope you enjoyed this introduction to motion capture technology. If you are still curious, you can read about another cool gadget we have in Taipei. Keep your eyes peeled for the next episode of Inside NMA.
Thanks for your support,
