The animation was called “Zeotrope,” some people may call the method “scanimation.” I made this animation in each shape with eleven continuous action frames. All eleven frames are minused back by underlying black slats. When the main black slat passed over, it perfectly align each frame for a moment in time. I created shapes in Illustrator then I output as PNG to After Effect to animate the black slats. Lastly, I put video with background music together in Premiere Pro.
This was not s super easy animation, but it is worth the time to learn the principle. It was amazing to look at as these dogs started running, although, my animation didn’t turn out as good as other video I found on the web.
