A local, browser-based video editor that turns one long-form video into ready-to-post vertical Reels. Load your raw footage, pick the short you want, and it builds a 50/50 split-screen clip with captions, sound effects, transitions, and an optional Claude mascot that hops on every word.

Runs entirely on your machine. No uploads, no per-clip credits, no subscription. Your footage never leaves your laptop.

Free to clone, personalize, and make your own.

Want the full video pipeline? Six skills for rough cut, captions, YouTube descriptions, Instagram captions, reel overlays, and content series live in leadgenman-video-skills, and the standalone SFX generator lives in soundeffects-claude-code.

What it does

• Auto-clips long videos into shorts. Feed it a face-cam recording and a screen recording, and it reads the transcript, finds the strongest moments, and assembles a vertical 1080x1920 Reel.
• 50/50 split screen. Screen recording on top, face cam on the bottom, with a draggable split handle so you can favor whichever matters in each scene.
• Auto retake removal. Recorded a line nine times? It keeps the cleanest take and drops the rest, then tightens the silences.
• Captions, your way. Multiple caption styles including karaoke, bold outline, and a pixel Claude mascot that hops word to word. Fonts, colors, size, casing, bounce, all customizable.
• Sound effects and music. Drop contextual SFX and background music on the timeline.
• Full manual control. Delete words or whole scenes, reorder clips, set per-clip pan and zoom, import B-roll and screenshots as overlays, undo/redo everything.
• Local and private. Projects save to disk and reopen exactly as you left them, weeks later. Nothing hits a server.
• Fast export. Renders MP4 with your system GPU. Preview equals export, no quality loss from your raw files.

Quick start

git clone https://github.com/manthanpatelll/repurpose-studio.git
cd repurpose-studio
npm install
npm run dev

Open http://localhost:3000 and you land straight in the studio.

You will also need ffmpeg on your PATH (used for video remux, proxies, and thumbnails). See SETUP.md for the full step-by-step, prerequisites, and how to personalize it.

How you use it

1. Record your long-form video (face cam + screen recording, frame-locked, same start and length).
2. Drop the two video files plus the transcript into ~/Downloads.
3. npm run dev, open the studio.
4. Load your raw footage. The tool transcribes locally and populates the timeline with the keeper takes.
5. Pick the short you want, customize captions, add SFX and music, set your framing.
6. Export. Your vertical Reel downloads to ~/Downloads, ready to post.

Full walkthrough in SETUP.md.

Make it yours

This is a starting point, not a finished product you have to accept as-is. It was built by describing features in plain English to an AI coding agent, and you can extend it the same way with whatever agent you use:

• Add your own caption templates (describe the style you want, preview it, then import the one you like).
• Swap the mascot for your own brand character.
• Change the split ratios, transitions, fonts, and colors to match your channel.
• Wire in your own sound effect library.

You do not need to write code. Open your coding agent in the terminal, tell it what you want, and let it build the feature.

Tech stack

Next.js 15 (App Router), React 19, TypeScript, Canvas 2D (no WebGL), Zustand, WebCodecs + Mediabunny for export, Tailwind v4, shadcn/ui. Local-only, not deployed anywhere.
