Adds one bar split into its parts to a talking-head video, each part drawing in as it is named, with a legend: what something is made of. Timed to the words they say, on their own footage, with their sound kept; 16:9, 9:16, 1:1 or 4:5. Renders locally with Chrome and ffmpeg: no video model, no key and no cost. Use when someone breaks something into its parts (an ingredient list, a price, a day).

About this skill

You say

In talk.mp4, when I say 600 hours a year, split the 600 hours into the parts of a status call: 250 going round the room, 150 reading the board aloud, 120 on side topics, 80 on real blockers. These are my own numbers and words, put them on screen as they are.

It said back

I rendered talk-graphics.mp4 in the work folder: 1920×1080, 24.3 s, 30 fps. I checked the settled frame in the check sheet and it showed no layout warnings. I didn't watch the rendered video itself.

  • What's on screen: one bar, "600 hours a year", split into Going round the room 250h, Reading the board aloud 150h, Side topics 120h and Real blockers 80h. The speaker slides to the right half while the bar fills the left.
  • Timing: it starts as you say "600 hours a year" at about 7.9 s and stays until about 14.9 s.
  • Look: paper, the warm off-white panels with a tomato accent.
  • Sound: yours, unchanged.
  • Unit: I wrote the values as "250h" and so on. With plain numbers the tool adds a "%" to the legend, which is wrong for hours. "250 hrs" wrapped onto two lines in the narrow segments, so I shortened it to "h".
  • Parts not tied to your voice: your transcript doesn't name the four parts, so they appear on the tool's default stagger within the beat rather than as you say them.

Questions

Is Composition Strip free?

No. Composition Strip costs $9.99 once and stays in your Recaply account, or it comes with the Recaply plan ($19.99 a month), which opens every premium skill and prompt.

Which agents can use Composition Strip?

Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode.

What do I get when I buy Composition Strip?

A ZIP of the whole skill folder (105 KB): the SKILL.md your agent follows and its 12 other files, the references, templates and scripts it uses. You download it from this page whenever you need it, and install it in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot and OpenCode. The Recaply plan opens it too, with every other premium skill and prompt.

How do I install Composition Strip?

Buy it, then download the ZIP from this page. For Claude Code, unzip it into .claude/skills/ in your project. For Codex, Cursor and Gemini CLI, unzip it and run npx skills add ./composition-strip-overlay with your agent's flag.

What do I get from Composition Strip?

Your video with the overlay timed to the words, sound kept. A single bar fills part by part, each in its colour, while a legend names them. 16:9, 9:16, 1:1 or 4:5.

What does Composition Strip need?

Node 22+, Chrome and ffmpeg, and no API key. Each use costs nothing beyond your agent.

How big is Composition Strip?

13 files, about 79,918 tokens in all. The SKILL.md is about 2,256 tokens, and your agent reads it only when the job fits.

What does a run cost?

Our 1 runs took 1 min 58 s to 1 min 58 s and $0.21 to $0.21 of API use each, in Claude Code with claude-sonnet-5-5. On a Claude plan, a run counts toward your usage instead.

Do I have to name Composition Strip to use it?

Type /composition-strip-overlay first to make sure it loads. Without it, Claude Code may judge a small job simple enough to do without the skill.
