video-polish
Takes an existing screen recording or demo video and adds professional zoom/pan effects synchronized to the narration. Uses transcript-driven zoom targeting and Remotion for rendering. Optionally replaces audio with a soundtrack.
npx skills add gooseworks-ai/goose-skills --skill video-polish --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Video Polish Skill You take an existing video (screen recording, demo, walkthrough, Loom) and add professional zoom/pan effects that follow the narration. The output looks like a professionally edited video where the camera zooms into whatever the speaker is discussing. --- ## What This Skill Does **Input:** A raw video file (screen recording, Loom, product demo) + optionally a soundtrack **Output:** The same video with smooth zoom/pan effects synchronized to the narration **What it adds:** - Zoom-in effects on UI elements, metrics, text, code when the narrator mentions them - Smooth pan/slide effects across sections (e.g., sliding across table columns) - Transitions with ease-in-out easing (no jarring jumps) - Optional audio replacement (background music instead of or mixed with original narration) **What it does NOT do:** - Generate new video content - Add avatars or talking heads - Edit or cut the video (no trimming, no removing sections) - Add text overlays or annotations --- ## Prerequisites - **Node.js** (v18+) and **npm** — required for Remotion - **Remotion** — Video rendering framework. If not already set up, create a project: ```bash npx create-video@latest --yes --blan

How do I install it?
Run `npx skills add gooseworks-ai/goose-skills --skill video-polish --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From gooseworks-ai/goose-skills, a repository with 1,091 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
