| 3 | # Remotion to HyperFrames |
| 4 | |
| 5 | > **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. |

| 7 | ## Overview |
| 8 | |
| 9 | 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. |
| 10 | |
| 11 | 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. |
| 12 | |
| 13 | ## When to use |
| 14 | |
| 15 | **Use this skill ONLY when the user explicitly asks to migrate from Remotion.** Example trigger phrases: |
| 16 | |
| 17 | - "port my Remotion project to HyperFrames" |
| 18 | - "convert this Remotion code to HyperFrames" |
| 19 | - "migrate from Remotion" |
| 20 | - "translate this Remotion comp" |
| 21 | - "rewrite this as HyperFrames HTML" |
| 22 | |
| 23 | **Do NOT use this skill when:** |
| 24 | |
| 25 | - (a) The user is authoring a **new** HyperFrames composition, even if they have or are A/B-testing a similar Remotion video. |
| 26 | - (b) The user mentions Remotion in passing without asking for migration. |
| 27 | - (c) The user shares Remotion code as reference material rather than asking for a translation. |
| 28 | - (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. |
| 29 | |
| 30 | **NOT SUPPORTED (decline — this is not what this skill does):** |
| 31 | |
| 32 | - **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. |
| 33 | - **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. |
| 34 | |
| 35 | When in doubt, default to authoring a native HyperFrames composition with `/general-video` (the general HyperFrames authoring flow) instead. |
| 36 | |
| 37 | ## Workflow |
| 38 | |
| 39 | ### Step 1: Lint the source |
| 40 | |
| 41 | Run [`scripts/lint_source.py`](scripts/lint_source.py) over the Remotion source directory. The lint detects patterns that can't translate cleanly: |
| 42 | |
| 43 | - **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). |
| 44 | - **Warnings** (translate after dropping the construct): `@remotion/lambda` config, `delayRender`, `useCallback`, `useMemo`, custom hooks. |
| 45 | - **Info** (translate with note): `staticFile`, `interpolateColors`. |
| 46 | |
| 47 | If any blocker fires, **stop**. Read [`references/escape-hatch.md`](references/escape-hatch.md) and surface the recommendation message. Warnings don't stop translation — drop the offending construct in step 3 and note the gap in `TRANSLATION_NOTES.md`. `@remotion/lambda` config is the canonical warning case: the skill drops the import + `renderMediaOnLambda(...)` calls but translates the rest of the composition. |
| 48 | |
| 49 | ### Step 2: Plan the translation |
| 50 | |
| 51 | Read [`references/api-map.md`](references/api-map.md) — the index of every Remotion API and its HF equivalent or per-topic reference. Identify which topic references you'll need based on what the source uses: |
| 52 | |
| 53 | | Source contains | Load reference | |
| 54 | | ------------------------------------------------------------------------- | --------------------------------------------- | |
| 55 | | `Composition`, `defaultProps`, `schema`, `calculateMetadata` |
