# Remotion to HyperFrames

> **The front door is `/hyperframes`.** Use this **only** to port an existing **Remotion** (React) composition's source into HyperFrames, one way. Authoring a **new** composition, re-creating from a non-Remotion source (After Effects, Framer Motion, plain React / CSS — there is no Remotion source to translate), a passing Remotion mention, or any uncertainty → read `/hyperframes` first: the intent layer owns every route decision.

## Overview

Translate Remotion (React-based) video compositions into HyperFrames (HTML + GSAP) compositions. Most Remotion idioms have direct HyperFrames equivalents — the translation is mechanical for ~80% of typical compositions. This skill encodes the mapping and guards against the lossy 20% by refusing to translate patterns that don't fit HF's seek-driven model and recommending the runtime interop pattern from [PR #214](https://github.com/heygen-com/hyperframes/pull/214) instead.

The skill ships with a **tiered test corpus** (T1–T4, 4 fixtures total) that grades translations against measured SSIM thresholds. Don't translate without running the eval — a translation that "looks right" but renders 0.05 SSIM lower than the validated baseline is silently wrong.

## When to use

**Use this skill ONLY when the user explicitly asks to migrate from Remotion.** Example trigger phrases:

- "port my Remotion project to HyperFrames"
- "convert this Remotion code to HyperFrames"
- "migrate from Remotion"
- "translate this Remotion comp"
- "rewrite this as HyperFrames HTML"

**Do NOT use this skill when:**

- (a) The user is authoring a **new** HyperFrames composition, even if they have or are A/B-testing a similar Remotion video.
- (b) The user mentions Remotion in passing without asking for migration.
- (c) The user shares Remotion code as reference material rather than asking for a translation.
- (d) The user asks for "the same video as my Remotion one" without explicitly asking to migrate the source — treat that as a fresh HyperFrames build.

**NOT SUPPORTED (decline — this is not what this skill does):**

- **The reverse direction.** Exporting a HyperFrames composition back out _to_ Remotion (or to any other framework) is not a workflow — the translation is Remotion → HyperFrames only. Say so plainly.
- **Non-Remotion sources.** An After Effects project (`.aep`), a Framer Motion / plain-React / CSS animation, or any other tool's source is not a Remotion composition — there is no Remotion source to translate. Re-create it natively via `/general-video`, or decline if HyperFrames can't represent it.

When in doubt, default to authoring a native HyperFrames composition with `/general-video` (the general HyperFrames authoring flow) instead.

## Workflow

### Step 1: Lint the source

Run [`scripts/lint_source.py`](scripts/lint_source.py) over the Remotion source directory. The lint detects patterns that can't translate cleanly:

- **Blockers** (refuse + recommend interop): `useState`, `useReducer`, `useEffect`/`useLayoutEffect` with non-empty deps, async `calculateMetadata`, third-party React UI libraries (MUI, Chakra, Mantine, antd, shadcn, Radix, NextUI).
- **Warnings** (translate after dropping the construct): `@remotion/lambda` config, `delayRender`, `useCallback`, `useMemo`, custom hooks.
- **Info** (translate with note): `static
