There's not really anything to show in a video. One moment it's correct, the moment I tap the keyframe it changes to the messed up one. Before attempting to use the keyframe bar, all joints can be manipulated normally.Looks to me like the process of painting the bones onto the models surface are not correctly done, causing deformations. Export to video it would give us a better idea of what is going on.
