Easy Interpolation

Inbetween frames for Aseprite 

Easy Interpolation is a free Aseprite extension that generates inbetween frames for pixel art animation. Select two drawings on the timeline, right-click, and it creates the frames in between.

It works like a motion tween for Aseprite: the extension detects what changes between your two keyframes and interpolates it. You can tween cel position, opacity, pixel crossfade, rotation and scale around a clickable pivot. Every channel uses easing curves, ease in, ease out, quad, cubic, sine, expo, back, elastic, bounce, so the motion feels natural instead of linear.

Typical uses: smooth sprite movement for games, fade transitions, rotating coins or items, squash-and-stretch style scaling, breathing/idle animations, and quick inbetweens between two hand-drawn poses.

Crossfade needs an RGB sprite; position, opacity, rotation and scale also work in indexed and grayscale mode.
