{"slug": "show-hn-diffusion-studio-plugin-for-codex-launch", "title": "Show HN: Diffusion studio plugin for codex launch", "summary": "Diffusion Studio released a Codex plugin, published as a private GitHub repository at Teseife/diffusion-studio-codex, that lets users create and edit video projects from OpenAI's Codex client and continue editing in Diffusion Studio. Installation requires a local Codex client with plugin support, Diffusion Studio on the same computer, and the `dapi` CLI installed via Settings → MCP & CLI; users register the diffusion-studio-community marketplace and run `codex plugin add diffusion-studio@diffusion-studio-community`. The plugin supports title cards, motion graphics, captions, previews, and 1080p MP4 export from prompts.", "body_md": "Create and edit video projects from Codex, preview your work, and continue editing in Diffusion Studio.\n\n## Diffusion-Studio-Plugin-Launch-v2-final.mp4\n\n**1:12 · 1080p · music and sound effects** — installation, a prompt in Codex, preview playback, and the editable Diffusion Studio timeline.\n\n- Create title cards, motion graphics, and short videos from a prompt.\n- Edit footage and arrange scenes in a local project.\n- Add readable captions.\n- Check a composition and capture previews.\n- Export a finished video when you're ready.\n\n- Install a local [Codex client](https://developers.openai.com/codex/cli) with plugin support and terminal/file access.\n- Install and open [Diffusion Studio](https://www.diffusion.studio/download) on the same computer.\n- In Diffusion Studio, go to **Settings → MCP & CLI** and install`dapi` for terminal workflows.\n\nWhile this repository is private, your GitHub account needs repository access to install it.\n\n1. Keep Diffusion Studio open and make sure `codex` is available in your terminal.\n2. Clone the repository, register its marketplace, and install the plugin:\n\n```\ngit clone https://github.com/Teseife/diffusion-studio-codex.git\ncd diffusion-studio-codex\ncodex plugin marketplace add .\ncodex plugin add diffusion-studio@diffusion-studio-community\n```\n\n1. Start a new Codex chat. In **Plugins** , search for`diff` , open**Diffusion Studio** , and choose**Try now** or select the plugin in your chat.\n\nKeep the cloned folder in place: Codex uses it as the local marketplace source. If the plugin doesn't appear, reopen the Plugins view or restart Codex after saving your work.\n\n## Alternative: install directly from GitHub\n\nWith authenticated Git access, you can register the GitHub marketplace without a manual clone:\n\n```\ncodex plugin marketplace add Teseife/diffusion-studio-codex --ref main\ncodex plugin add diffusion-studio@diffusion-studio-community\n```\n\n## Ask Codex to help install the plugin\n\nUse a local Codex chat on the computer running Diffusion Studio:\n\n```\nHelp me install the Diffusion Studio plugin from\nTeseife/diffusion-studio-codex on this computer.\n\nCheck existing installations first and use my existing Git authentication.\nRegister the diffusion-studio-community marketplace and install\ndiffusion-studio@diffusion-studio-community. Check that the plugin is\nenabled and run its bundled connection diagnostic. Explain any missing\ndependencies or repository-access problems. Preserve my existing projects.\n```\n\nStart a new chat after installation to load the plugin's tools.\n\nFirst, ask Codex:\n\nCheck my Diffusion Studio connection and explain what I can do with it.\n\nThen try the prompt from the demo:\n\nCreate a short animated video showcasing this plugin's capabilities: create and edit video, add captions, preview, and export. Use kinetic typography and show me a preview.\n\nReview the preview, ask for changes, and open the project in Diffusion Studio to work with its canvas and timeline. When you're happy with the result, ask Codex to export the video.\n\nCreate a five-second title card in a new project that says \"Made with Diffusion Studio.\" Show me a preview.\n\nEdit this footage into a short video and add readable captions.\n\nMake the title orange, tighten the pacing, and show me the updated preview.\n\nExport the current composition as a 1080p MP4.\n\nFor the local clone installation, run these commands inside the cloned repository:\n\n```\ngit pull --ff-only\ncodex plugin add diffusion-studio@diffusion-studio-community\n```\n\nFor the direct GitHub marketplace installation:\n\n```\ncodex plugin marketplace upgrade diffusion-studio-community\ncodex plugin add diffusion-studio@diffusion-studio-community\n```\n\nStart a new Codex chat after updating.\n\n**Plugin missing?** Check the installation:\n\n```\ncodex plugin list --marketplace diffusion-studio-community --json\n```\n\nLook for `diffusion-studio@diffusion-studio-community` with `enabled: true`, then open a new chat.\n\n**Editor connection unavailable?** Open Diffusion Studio and check **Settings → MCP & CLI**. From the cloned repository, run the optional diagnostic with Python 3:\n\n```\npython3 plugins/diffusion-studio/scripts/doctor.py\n```\n\nA ready connection reports `mcpReady: true`.\n\n**Clone or download fails?** Sign in to GitHub with an account that has repository access. You can also download the repository ZIP while signed in, extract it, and run the two `codex plugin` install commands from that folder. Keep the extracted folder in place; download a fresh copy when updating a ZIP installation.\n\n**Duplicate Diffusion Studio entries?** If you also have the personal `diffusion-studio-local` version installed, enable one copy at a time.\n\n- This is an independent community plugin, unaffiliated with Diffusion Studio or OpenAI. It isn't listed in the OpenAI public plugin directory.\n- Codex connects to Diffusion Studio's local MCP server at `http://127.0.0.1:3274/mcp` . Use local Codex execution on the computer running the editor; cloud execution cannot reach that local address.\n- macOS has been tested. Windows support has not been verified. Optional generation and analysis features use the services configured in Diffusion Studio.\n- The demo combines recreated GitHub, terminal, and Codex interactions with real Diffusion Studio project output and an editor capture.\n- Plugin code and the independent plugin icon are [MIT licensed](https://github.com/Teseife/diffusion-studio-codex/blob/main/LICENSE) . Diffusion Studio is a separate dependency with its own terms; third-party branding in the demo and screenshots is not covered by this project's MIT license.\n\nSee [validation and limitations](https://github.com/Teseife/diffusion-studio-codex/blob/main/VALIDATION.md), [release notes](https://github.com/Teseife/diffusion-studio-codex/blob/main/CHANGELOG.md), and the [plugin package guide](https://github.com/Teseife/diffusion-studio-codex/blob/main/plugins/diffusion-studio/README.md).", "url": "https://wpnews.pro/news/show-hn-diffusion-studio-plugin-for-codex-launch", "canonical_source": "https://github.com/Teseife/diffusion-studio-codex", "published_at": "2026-10-02 04:33:41+00:00", "updated_at": "2026-10-02 04:46:11.493125+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools", "ai-tools", "agent-protocols", "ai-products"], "entities": ["Diffusion Studio", "Codex", "OpenAI", "Teseife/diffusion-studio-codex", "dapi", "diffusion-studio-community"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-diffusion-studio-plugin-for-codex-launch", "markdown": "https://wpnews.pro/news/show-hn-diffusion-studio-plugin-for-codex-launch.md", "text": "https://wpnews.pro/news/show-hn-diffusion-studio-plugin-for-codex-launch.txt", "jsonld": "https://wpnews.pro/news/show-hn-diffusion-studio-plugin-for-codex-launch.jsonld"}}
