An AI agent skill that turns one talking-head clip into a finished vertical video, in your own style. Give it a
take; it cuts the edit, writes the captions, builds the motion graphics and lays the sound, then shows you a
storyboard to comment on before anything renders.
Works with Claude Code, Claude Cowork, Codex and ChatGPT Work. Runs on your computer, on your footage. Free and
open source.
One edit, three style packs. Same cut, same effects, same timing; the look is the pack's. Every image in this
README is drawn on a stand-in figure.
What it makes
- A clean edit of one take: dead air out, the last good take of every line, J-cuts on every join, two framings
from one camera, lip sync checked before and after the render.
- Captions that land on the words, in your fonts and colours.
- Words and numbers behind your head (you stay in front of the type).
- Hand-built motion-graphic cards for the numbers in your script: charts that draw, figures that roll, data kept
to scale.
- Sound effects under every visual moment, mixed under your voice to streaming loudness (-14 LUFS).
- A storyboard first: every beat with real frames, what moves, what you hear, and what the agent needs from you.
Leave notes on any beat. Nothing renders until you say go.
Three modes
- **Hi-fi**: produced. A sit-down take, full-screen data cards, type behind your head.
- **Lo-fi**: selfie. A phone take where you never leave the frame; screenshots and clips land on top of you or
behind your head, captions light up word by word, native-looking text boxes carry the hook and the call to action.
- **Showcase**: the show-off edit. Every line gets a different hand-built motion graphic the words call for (kinetic
type, a magazine cover behind your head, a grade that wipes across, a grid of you, a timeline that builds), a
different transition on every cut, and dense sound. Seventeen effects ship in the library.
Your style decides how each mode edits for you, not just its colours: the hook shape, how captions move, what the
camera does, which transitions you use and how a big word lands all come from your brand and your inspiration.
The effects
Seventeen hand-built motion graphics for showcase videos, each one driven by your style pack: kinetic type, a word
stamped behind your head, giant captions, a typing prompt bar, comment threads, a magazine cover, an editing
timeline built from your own video, a grade that wipes across, a grid of you, a frame that recurses into itself,
and more. What each one does and when to reach for it: fx/LIBRARY.md.
Your style, not ours
The first time you run it, the agent builds your style pack:
1. **Have a brand file?** A brand guide, a DESIGN.md, a PDF or your website. It reads your fonts and colours.
2. **No?** Send 2 or 3 links to videos whose style you like. It studies them: pace, captions, colour, motion.
3. **Neither?** Four quick questions.
Then it shows you a style board: your type and colours, a frame of your own footage in each of the three modes,
and a few cards in your look, and asks if it looks like you. Change anything, any time: "update my style".
The pack lives in ~/reel-kit/style/, outside the skill, so updates never touch it. Each video keeps a copy of
the style it was made with.
Install
It runs on your own computer, on your own footage: a Mac or Linux (Windows is untested; WSL should work) with
