Adds big keyword captions to a talking-head video: the one to six words that matter land in large type, word by word, as they are said, with a word in the accent. 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 wants the main phrases of a short (a Reel, a TikTok, a Short) to hit in big type as they say them.

About this skill

You say

Make "600 hours a year" and "dropped by 40%" land as big keyword captions in talk.mp4.

It said back

I rendered talk-graphics.mp4 in the work folder, with both phrases as big keyword captions. It is 1920x1080 at 30 fps and 24.3 s long. I checked the settled frames in the check sheet, but I haven't watched the rendered video through.

The sound is hers and unchanged.

What do I get when I buy Keyword Captions?

The Recaply plan opens it too, with every other premium skill and prompt.

How do I install Keyword Captions?

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 ./keyword-captions-overlay with your agent's flag.

What do I get from Keyword Captions?

Your video with the overlay timed to the words, sound kept. Each part lands as they say it, placed from the transcript. 16:9, 9:16, 1:1 or 4:5.

What does Keyword Captions need?

13 files, about 79,967 tokens in all. The SKILL.md is about 2,305 tokens, and your agent reads it only when the job fits.

What does a run cost?

Our 1 runs took 1 min 51 s to 1 min 51 s and $0.13 to $0.13 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 Keyword Captions to use it?

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