# Render repeatable videos from HTML instead of a video model

> A hands-on test of HyperFrames, an open-source tool that turns timed HTML pages into MP4 with headless Chrome and ffmpeg. Same input gives the same video, so changes are code edits instead of another roll of the dice. The tester also wrote down the gotchas.

## What you end up with

Use this when you need text that stays sharp, brand colors that never drift, or many versions of the same video.

## What you get

- A plain-language summary of the workflow
- A fill-in prompt template
- What to watch out for
- A link to the original source

## Who it is for

Builders who already use AI agents and want a proven workflow they can copy into their own project.

## Tools needed

- HyperFrames: renders HTML pages with timing attributes into frames
- Headless Chrome: captures each frame
- ffmpeg: encodes frames to MP4
- Claude Code or Codex: writes the scenes using the bundled agent skills
- You need: An AI coding agent or chat model
- You need: A small real task to try it on

Cost to run: Free with the agent plan you already use.

## How it works

1. **Install Node 22 or newer and ffmpeg, and point TMPDIR at a disk with r.** Install Node 22 or newer and ffmpeg, and point TMPDIR at a disk with real space Expected: Done before you move to the next step.
2. **Start a project and ask your agent to write one scene with timed eleme.** Start a project and ask your agent to write one scene with timed elements Expected: Done before you move to the next step.
3. **Render 5 seconds first and time how long it takes on your machine.** Render 5 seconds first and time how long it takes on your machine Expected: Done before you move to the next step.
4. **Keep all copy and colors in one data file so versions are a data chang.** Keep all copy and colors in one data file so versions are a data change Expected: Done before you move to the next step.
5. **Check the output frames at the start, middle and end before rendering .** Check the output frames at the start, middle and end before rendering the full length Expected: Done before you move to the next step.

## Sample prompt: Workflow template (HyperFrames, Headless Chrome)

```
Apply this workflow to [your project]:
1. Install Node 22 or newer and ffmpeg, and point TMPDIR at a disk with real space
2. Start a project and ask your agent to write one scene with timed elements
3. Render 5 seconds first and time how long it takes on your machine
4. Keep all copy and colors in one data file so versions are a data change
5. Check the output frames at the start, middle and end before rendering the full length
Stop and ask me before anything irreversible: deploys, payments, sends or deletes.
```

# Render repeatable videos from HTML instead of a video model

PaperChase agent use case (free feed entry), version 1.0. Source: [@ChenBuildsAI on X](https://x.com/ChenBuildsAI/status/2114328095851176423), 2026-10-25.

## What they did

The tester ran npx hyperframes init, wrote a page with timing data attributes and rendered 10 seconds of 1080p. Their notes: the render refused to start because /tmp was a small memory disk, fixed by pointing TMPDIR at real storage; on software graphics it fell back to slower screenshot capture (44 seconds for 10 near-empty seconds); it needs Node 22 or newer and ffmpeg. A second builder reports the same idea, agent-written HTML scenes rendered by headless Chrome and ffmpeg, running on a small cheap server.

## Worth knowing

Use this when you need text that stays sharp, brand colors that never drift, or many versions of the same video. Use a generative model when you want invented footage. Set TMPDIR before running it on CI or a small VM.
