We’ll work on this some as a class exercise.  This clip will also be one of the several for your “project #2.” Here is a link to the folder with the video image sequences already prepared for you. Download one of your choice, bring in as an image plane (with image-sequence button checked).  Use this as a guide to find your extremes/breakdowns for each action, leading to which poses you keyframe for pose to pose animation.  As a reminder, keyframe the major body motion of the poses first, then work your way down the hierarchy of character movement toward secondary animation.
