How avar values generate to get realistic movement
There are numerous ways of generating avar values to get realistic movement. One way is to use markers on a real person (or whatever is being animated) acting out a part and track movements by video camera. Otherwise, avars can be set manually using a joystick. Software produces a level of quality for movie animation which would take several years to produce by hand and would use several animators/cartoonists. This all saves considerable money and time to the film and television producers.
