What it does

This skill provides step-by-step guidance and templates to generate programmatic motion graphics and short animated videos in a sandboxed environment. It explains how to choose resolution, duration, and framerate, how to render frames programmatically (Pillow / matplotlib) or via FFmpeg filters, and how to assemble frames into a playable MP4 using FFmpeg with compatible settings. The skill includes practical tips for resource management and encoding compatibility so outputs play across devices.

When to use it

Use this skill when you need: a quick intro animation, animated data visualizations, text-based motion graphics for social clips, or diagrammatic animations for documentation. It is especially useful in environments where writing a frame-by-frame renderer or assembling frames with FFmpeg is preferred over heavier video tools.

What's included

Scripts: template generator script referenced (scripts/generate_motion.py) for frame-by-frame rendering (frame export + ffmpeg assemble).
References: technique notes covering FFmpeg filters and animation best practices.
Instructions: clear workflow — define animation params, pick an implementation strategy (frame-by-frame, FFmpeg filters, or matplotlib), implement drawing logic with a progress variable, export numbered frames, then assemble with FFmpeg and clean up temporary files.
