Lynda - 2D Animation: Character & Attitude Walk Cycles

Once you've completed a basic walk cycle, it's time to add character. Animator Dermot O' Connor shows how to take a basic walk and go beyond, building in personality, exaggeration, and attitude. Learn how to animate bipedal motion, stomps, sneaks, and goofy walks, and turn walks into full-on runs. Dermot also shows how to avoid common pitfalls such as jagged arcs. These techniques are 2D animation classics, and must-have skills for any animator, regardless of software.
Topics include:

Animating male and female walks
Changing weight and body type
Breaking joints for flexibility
Creating an attitude contact pose
Animating a jog or run in 10, 8, or 6 frames
