 Make something worth watching

From a quick social clip to a longer edit, OpenReel gives you a timeline, a live preview, and control over the details.

| What you want to do | What you can use |
| :--- | :--- |
| Get to the good part | Trim, split, crop, ripple delete, rearrange clips, and change playback speed. |
| Build your story | Stack video, audio, text, and graphics on multiple tracks. Add transitions and animate with keyframes. |
| Make every word readable | Create and style captions, import SRT subtitles, and add animated titles. |
| Make it sound right | Mix music and dialogue with waveforms, volume controls, fades, EQ, compression, and audio ducking. |
| Find your look | Adjust color with wheels, curves, HSL controls, and LUTs. Add effects, masks, and chroma key. |
| Fit the platform | Work in landscape, portrait, or square, then choose export resolution, frame rate, and bitrate. |

 Edit with an AI assistant

Connect your own OpenAI, Anthropic, or compatible endpoint to make reversible timeline edits. Model connections and session keys are configured in Settings → AI Editor. See the AI editing guide for setup, supported tools, and edit-sharing behavior.

 Start editing in minutes

1. Open OpenReel and create a project.
2. Import your media and drag clips onto the timeline.
3. Shape your edit with cuts, captions, music, color, and transitions.
4. Export your video using a preset or your own settings.

The browser editor needs no installation. For a native app, download a macOS, Windows, or Linux build from Releases. Desktop builds are currently in alpha.

 Keep control of your footage

Core editing and rendering happen on your device. You can import, cut, preview, and export local media without uploading it to a server.

- No export watermark. Your finished video stays yours.
- Open source, MIT licensed. Use it for personal or commercial work, inspect the code, or host your own copy.
- Save as you work. Local autosave and undo/redo help you recover edits. Export project files for backups and moving between sessions.
- Choose when to connect. Optional AI and connected services use network requests; their data handling depends on the provider and feature you choose.

Browser storage can be cleared by your browser. Keep backups of your project files and original media for work you want to keep.

 Export for the next step
