What problem does it solve?

This Skill removes the time-consuming trial-and-error of manually designing and exporting short motion-graphic B-roll clips for talking-head videos.

Core Features & Use Cases

• HTML/CSS/SVG motion authoring: Create 1–6 second overlay animations such as icon morphs, label fades, self-drawing diagrams, side-by-side comparisons, and simple flow charts.
• Deterministic MP4 rendering pipeline: Renders frame-accurate MP4 output using Playwright + ffmpeg so clips can be dropped directly into a video editor.
• Script-driven clip generation: Supports multiple [ANIMATION] callouts inside pasted video scripts, treating each callout as a separate clip with consistent sequencing conventions.
• Brand-aware styling hooks: Stays brand-agnostic by default, but can pull colors/typography/voice from a brand-system skill when applicable.

Quick Start

Build a 5-second B-roll animation from your pasted script by telling the AI: "Use the animation callouts in my script to create the required MP4 overlays (default 16:9) and render each clip in order."
