Introduction• Motion capture is the process of recording human movement
through specialized camara’s and mapping them into a character model
• Motion capture technology involves sensing,digitizing,andrecording that object in motion
• It is also known as MO-CAP, Virtual, theater, Real-time animation or performance Animation

The Birth Of Motion Capture• Historically motion
capture in animated movies was created using the extension of “ROTOSCOPING” technique

•A Rotoscoping is a device that enables animation to trace live action movement,frame by frame,for use in animation

• Capture Video :
Rotoscoping works by first capturing a video of a real actor around props that resembles elements of scene

ROTOSCOPING• Tracing :
• Animation then
trace over each
frame of the
recorded video
this would result
in a figure that
moved in a very
realistic fashion

Post Processing :
Finally true animated figured would be colored and then integrated with various background layers to create the final shot

Marker Placement
• Location should move rigidly with joints
• Stay away from bulging muscles
