Open-source AI video editing, run by your agent
Captioning a week of clips means opening an editor, waiting on a transcript, styling the text, and exporting one file at a time. OpenEdit takes the whole job off your hands. Install one command, tell your AI agent to add subtitles to your video, and it will transcribe the audio, design a caption style that fits the footage, and render the clip.
OpenEdit edits footage rather than generating it, so bring your own from wherever you already work. The editor is free and open source, and rendering happens on your own machine. It suits anyone shipping Reels, Shorts, TikToks, or podcast cuts every week, and anyone who wants an open-source AI video editor they can wire into a pipeline they already run. Need the same job as a hosted endpoint instead? That is what VEED's Subtitles API is for.
How to caption a video with OpenEdit:
Step 01
Install the skill
Run npx skills add veedstudio/open-edit in your terminal. That is the only setup step. Open your agent afterwards, and it handles the rest itself.
Step 02
Ask your agent to add subtitles
Say, "Add subtitles to my video [VIDEO]," or run /open-edit on a selected clip. Your agent transcribes the audio, reads the transcript, and designs a caption style automatically. No manual timing, no styling step.
Step 03
Get your captioned video back
One to three minutes later you get an MP4 with subtitles burned in, and a preview window opens. Keep prompting to change the color, the placement, or the emphasis. Prefer to work in a timeline instead? Add subtitles to a video in the VEED editor.

A week of captioned clips, without opening an editor
Ship reels, shorts, TikToks, and podcast cuts straight from your agent. One prompt returns a finished MP4 with subtitles burned in. No timeline to build, no UI to learn, no subscription to keep paying for.

Captions that look like your brand made them
Point OpenEdit at a reference image, a Figma layout, or your brandbook, and every clip after it matches. Ask for something dynamic, something clean, or a specific color and placement, and it reworks the result. Caption styling happens in HTML and CSS, so anything you can express there, you can render.

Built to run at volume, inside the tools you already use
Batch a client's week through a multi-agent session instead of paying studio rates. Connect any MCP or API, make OpenEdit part of your existing workflow and skillset, or build something new around it. For hosted, high-volume captioning without an agent in the loop, see VEED's Subtitles API, or compare the wider category in the best subtitles APIs.
FAQ
OpenEdit is VEED's agent-native video tool: an open-source editor your AI agent runs, paired with VEED Engine, the renderer behind it. Tell your agent to add subtitles to a video, and OpenEdit transcribes the audio, designs a caption style that fits the footage, and returns a ready-to-post clip. It edits footage rather than generating it, so bring your own. It is in beta and available now on GitHub.
The OpenEdit editor is under Apache-2.0. Read it, fork it, ship it. The renderer binaries are closed source, under PolyForm Shield 1.0.0, and you can sell what you make with them at no cost to VEED. You are not locked to them either: composition does not depend on VEED's renderer, so if a closed binary is a dealbreaker, you can render through Chrome instead. Both licenses are in the repo.
OpenEdit is agent-agnostic. It has been tested with Claude Code, Codex, and Gemini. The skill prepares the runtime and loads its AGENTS . md explicitly, so it is not tied to one model.
Both let an AI agent drive video captioning, and both let you style in HTML and CSS. The difference is underneath. Remotion renders with a headless browser. VEED built its own HTML-to-video renderer with no headless browser in the pipeline, and it runs locally on your machine. In VEED's early internal benchmarks, it ran up to 2.2x faster than tools that drive Chrome. That is VEED's own testing rather than a published comparison, and reproducible benchmarks are coming in the next few weeks.
OpenEdit is free to use. No subscription, no paywalls. One veed.io account for transcription. Transcription is built in. The default workflow gives you access to VEED's transcription when you provide a VEED account. Your audio — not the video — is uploaded and stored to transcribe it, and the limits are whatever your VEED account already has.
OpenEdit runs on Apple Silicon Macs on macOS 26 (Tahoe). Not Intel, and not earlier versions of macOS. Windows and Linux support is something VEED intends to build, and how it gets prioritized depends on the demand. V1 is built around captions, and the engine already renders motion graphics, charts, and brandbook-matched styling, which is worth pushing on and is also where it is roughest today.

More than a captioning skill
OpenEdit edits footage you already have. When you need the footage itself, that is a different job, and it lives in VEED, an AI video creation platform where generation is the starting point rather than the finish line. Generate a talking head from a script with Fabric through the VEED MCP, remap lips to new audio with the Lip Sync API, or caption at volume with the Subtitles API. Refine what comes back with transcript editing and Auto Edits, apply your brand kit so the result looks like your brand made it rather than AI, and export post-ready video in minutes. OpenEdit brings the same rendering to agent-native workflows, open source and running on your own machine.
