HyperFrames + Codex: How to Make a Free AI Launch Video

You do not need a video-generation model to make a product launch video. HyperFrames has an AI coding agent write HTML, CSS, and JavaScript, then renders that composition to MP4. The storyboard is a file. The preview is a local editor. The export is a normal video.

HeyGen's docs describe HyperFrames as free and open-source. Local rendering does not use HeyGen credits. Your coding agent (Codex, Claude Code, and similar) and any optional hosted voice, avatar, or generated-media services can still cost money.

What HyperFrames is

HyperFrames is a framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 files. You can run it from an AI coding agent with skills, from a local Studio-style preview, or from the CLI.

The official quickstart is here: Make your first video.

Install the skill, then generate from one prompt

In the video we copy the HyperFrames skill into Codex the same way as any other Codex skill. HeyGen's current documented install is:

• In your project folder run: npx skills add heygen-com/hyperframes --full-depth
• Choose Core Skills in the picker so the /hyperframes router is available.
• Open or restart the coding agent in that folder, then ask for a video.

The demo prompt was deliberately underspecified: generate a launch video for the MacBook Neo, with no product screenshots and no script. Codex still wrote a storyboard, built the composition, and produced a first cut. That is the point of the demo — the floor is now "one sentence." Your real launch should not stay that empty.

Edit the storyboard before you fall in love with the render

The storyboard file is where you inject taste. Change the beats, the on-screen claims, and the timing there instead of arguing with a black-box video model. If you have a logo, product screenshots, and a script, drop them in the project folder and tell the agent to use them. First-try quality jumps when the agent is not inventing the product.

Use the local preview, then export MP4

HyperFrames opens a local preview editor. You can restart it later with npx hyperframes preview inside the project folder. In the video we attach a real laptop photo, ask for tighter spacing, and let Codex inspect the image dimensions and update the composition. When the cut is right, export and download an MP4.

If the sandbox blocks a command, Codex will usually print the exact terminal line to paste. That is normal, not a broken install.

What is actually free

• The HyperFrames framework, local preview, and local render: free, no HeyGen credits.
• Codex, Claude Code, Cursor, or whatever agent writes the HTML: billed by that vendor.
• Optional HeyGen-hosted voice, avatar, or generated media: billed separately if you turn those on.

So "free launch video" is true for the renderer. It is not true if you burn a frontier coding model for an hour, and it is not a replacement for a designer on a flagship brand film.

When this workflow wins

• You need a 10–30 second launch, explainer, or changelog clip and you can describe the product in a folder of assets.
• You want revision control — the video is code — instead of regenerating a whole clip from a new prompt.
• You are already comfortable with Codex or another coding agent.

Skip it if you need photoreal talking heads as the core of the video, or if you will not review on-screen text for factual errors. The first cut is not a guaranteed final.

If you are new to Codex skills, pair this with the same skill workflow we use for other agent tools in MCP servers explained, then come back and generate the clip.

Bottom line

HyperFrames turns a coding agent into a video engine. Install the skill, give it a URL or a product folder, preview locally, export MP4. Add real assets if you care about the result. That is a better default for many launch videos than waiting on a specialist tool — and it is honest about what still costs money.
