BPC: Art and Computation – Fall Animation example – slow

BPC: Art and Computation – Fall Animation - timing Speed of action Synchronization of actions Synchronization with sound –Sound track recorded first –Animation made to match sound

BPC: Art and Computation – Fall Animation – timing control Fixed speed projection –Film 24 fps –Video 30 fps –Computer graphics 60, 72, 75 Hz refresh rate Image redraw may not match this speed How vary action speed?
