Animation Worksheet: Keyframes and In-Betweens

Animation and design lesson 4: Keyframes and in-betweens · Set 307 · 40 questions
TalentJR

Creator's tip (Keys, then in-betweens): Keyframes = the main poses; in-betweens = the drawings between them; tweening = the app makes the in-betweens. In-betweens between two keyframes = second frame number − first frame number − 1. Equal steps: one step = distance ÷ number of steps. Drawings in all = keyframes + in-betweens.
