Keyed is a Python library for creating programmatically defined animations. Named after key frames, the defining points in an animation sequence, Keyed makes it easy to create sophisticated animations through code.

Features

  • Reactive Programming Model: Built using the reactive programming library signified to make declaratively defining highly dynamic animations a breeze
  • Vector Graphics: Cairo-based rendering for crisp, scalable graphics
  • Flexible Shape System: Define basic lines, shapes, curves, and complex geometries
  • Code Animation: Animate syntax highled code snippets

Installation

Keyed requires a couple system level dependencies (e.g., Cairo and ffmpeg).

For detailed installation instructions visit our Installation Guide .

But, once you have the necessary system dependencies installed, installing keyed is as simple as,

pip install keyed

Project Status

This project is in beta, so APIs may change.

Alternatives

While I find keyed very fun and useful (particularly for animating syntax highlighted code in my YouTube videos), there are several other excellent and far more mature animation libraries that you should probably use instead.

Before you decide to use keyed, be sure to check out:

  • Manim: Comprehensive mathematical animation system originally created by Grant Sanderson of the YouTube channel 3blue1brown, but later adopted and extended by the manim community.
  • py5: A Python wrapper for p5, the Java animation library.
