# HyperFrames

HyperFrames is the rendering layer in Cole's fully agent-produced video workflow: it takes animated scenes defined in plain markup and renders them to video, with a preview editor an agent (or a human) can open and adjust before committing to a final MP4. Cole puts it at the center of the stack: "the biggest kit on the block here is HyperFrames. This is what lets our AI agents render these scenes and have that editor that I was just showing you" [0:00:30].

The reason it fits an agent so well is the format it uses. "then we create this index.html. This is what I love about hyperframes. It's literally just HTML. It's super easy to create and mold" [0:09:12]. HTML is the single most familiar output format an LLM has, so the agent is not learning a bespoke DSL; it is writing the thing it already writes best. That also makes iteration cheap and surgical - an awkward transition can be fixed in the composition without re-running the entire render.

In the end-to-end workflow, HyperFrames sits after scripting and narration. The agent writes a script, makes one text-to-speech call for the full audio track, then syncs animation timing to that audio (audio first), builds the `index.html` composition, lints it, inspects frame by frame for layout overflow, and opens a local preview for review. That frame-by-frame inspection pass is a [visual self-validation loop](../../concepts/visual-self-validation.md) in miniature: the agent looks at its own rendered output and edits the source rather than trusting that the markup was right.

Cole's positioning against the incumbent is explicit. Remotion went viral as the first tool to hand Claude Code a video-generation [skill](../../concepts/skills.md), but he found it unreliable in practice and calls HyperFrames "definitely a step up." The whole stack around it is also free-tier viable when paired with [Kokoro](./kokoro.md) instead of a paid TTS provider.

## Realizes

- [Visual Self-Validation Loop](../../concepts/visual-self-validation.md) - Giving an agent the ability to render its own visual output, look at it, spot imperfections, and edit the source in place; the preview editor and frame inspection are that loop.
- [Skills](../../concepts/skills.md) - Reusable, model-invoked capability packages loaded on demand; the whole video workflow ships as a single Claude Code skill wrapped in an Archon workflow.
- [Generative UI](../../concepts/generative-ui.md) - Code-defined visual output generated at runtime, which is exactly what an agent-authored HTML composition is.

## Contrasts with

- [Remotion](./remotion.md) - The earlier tool that first gave Claude Code a skill to generate videos; Cole found it less reliable than HyperFrames.
- [Higgsfield](./higgsfield.md) - A video-generation platform with a CLI that generates footage outright, where HyperFrames composes deterministic scenes from markup you control.
- [Sora 2](./sora-2.md) - OpenAI's video-plus-audio generation model that took the world by storm in 2025 and drew a $1B Disney investment.

## Works with

- [Claude Code](./claude-code.md) - Anthropic's terminal-based agentic coding assistant, the agent that writes the composition and drives the render.
- [Archon](./archon.md) - Cole's open-source harness builder, supplying parallel execution, durability, and run isolation around the workflow.
- [ElevenLabs](./elevenlabs.md) - The paid text-to-speech provider used for high-quality narration synced to the rendered animation.
- [Kokoro](./kokoro.md) - The free, open-source text-to-speech model that makes the same pipeline cost nothing to run.

- [Effective Prompting](../../concepts/effective-prompting.md) - Keeping prompts simple, specific, and high quality; the scripts feeding this pipeline are heavily prompt-engineered with TTS tags and breaks.
- [Agentic Workflow Engineering](../../concepts/agentic-workflow-engineering.md) - Designing repeatable AI workflows as engineered systems with defined steps and orchestration.
- [Reusable Components and Variables](../../concepts/reusable-components.md) - Packaging sub-workflows for reuse; here the templates that fix scene structure, style, and length.
- [Excalidraw](./excalidraw.md) - Diagramming tool whose JSON a coding agent can generate directly, the same trick of picking a format agents already write well.
