* docs(skills): add cloud render + variables to CLI skill, media-use generative use cases The hyperframes-cli skill only documented self-managed AWS Lambda rendering; the zero-infra HeyGen-hosted `cloud render` path (a real, shipped command with its own docs page) was absent from every skill, so agents never surfaced it. - hyperframes-cli: add `cloud` to the frontmatter verb list + entry point; new Cloud and Variables sections; new references/cloud.md distilled from docs/deploy/cloud.mdx; routing + workflow rows. - media-use: add image-to-video recipe (heygen video create type:image) plus a table of other HeyGen generative use cases (photo avatar, digital twin, video translation, lipsync, voice design) in references/operations.md; surface them in the SKILL coverage/provider rows. - Sync README + docs/guides/skills.mdx catalog entries to mention cloud render. * docs(media-use): point HeyGen generative use cases at --request-schema Verified against the installed heygen CLI (v0.3.0): no capability gap that would need the raw API. Replace hardcoded body-field lists with a pointer to `heygen video create --request-schema` (self-documenting, can't rot), correct the image-to-video motion_prompt/expressiveness support, and add the cinematic_avatar, ai-clipping, and photo-avatar creation paths. * fix(skills): correct media-use manifest hash (clean-tree regen) The prior regen was polluted by the gitignored skills/media-use/eval-report.html (a suppressed mv error left it present), so the committed media-use hash didn't match a clean checkout. Regenerate with no untracked artifacts present.

# cloud — HeyGen-hosted rendering (zero-infra)
|
||
|
||
`hyperframes cloud render` renders a composition on HeyGen's managed cloud. The CLI zips the project, uploads it, runs the render on HeyGen's infrastructure (Chromium + FFmpeg), and downloads the finished video. Nothing to deploy, and no Chrome/FFmpeg/AWS to manage; you pay per credit.
|
||
|
||
```bash
|
||
npx hyperframes auth login # one-time sign-in
|
||
npx hyperframes cloud render # zip, upload, render, download
|
||
```
|
||
|
||
## When to use cloud vs lambda vs local
|
||
|
||
- **`hyperframes render`** (local): fastest iteration loop, use while authoring.
|
||
- **`hyperframes cloud render`**: zero-infra. HeyGen runs the render and you pay per credit. This is the default answer to "render in the cloud" when you don't want to manage Chrome/FFmpeg/AWS.
|
||
- **`hyperframes lambda render`**: bring-your-own-AWS distributed rendering with chunked parallelism. Only worth it when you've already invested in AWS (see `lambda.md`).
|
||
|
||
## Authentication
|
||
|
||
Cloud rendering needs a HeyGen credential, stored at `~/.heygen/credentials` (`0600`) and shared with the [`heygen` CLI](https://github.com/heygen-com/heygen-cli): sign in with one and the other picks up the session.
|
||
|
||
```bash
|
||
npx hyperframes auth login # OAuth 2.0 + PKCE, opens the browser
|
||
npx hyperframes auth login --api-key # CI/headless: hidden prompt, or pipe: echo "$HEYGEN_API_KEY" | ... --api-key
|
||
npx hyperframes auth status # active credential source, identity, billing snapshot
|
||
npx hyperframes auth refresh # force-refresh an OAuth token before a long job
|
||
npx hyperframes auth logout # clear the stored credential
|
||
```
|
||
|
||
Credential resolution order (first match wins): `HEYGEN_API_KEY`, then `HYPERFRAMES_API_KEY`, then `~/.heygen/credentials`. Point at a different backend with `HEYGEN_API_URL` (default `https://api.heygen.com`).
|
||
|
||
## The render pipeline
|
||
|
||
`cloud render` runs end-to-end:
|
||
|
||
1. **Resolve the project**: a local directory (default `.`), or skip the upload with `--asset-id` / `--url`.
|
||
2. **Auto-detect aspect ratio** from the entry HTML's `data-width`/`data-height`.
|
||
3. **Zip** the project (same ignore set as `hyperframes publish`, so it excludes `.git`, `node_modules`, `dist`, and so on).
|
||
4. **Upload** the zip to `POST /v3/assets`, yielding an `asset_id`.
|
||
5. **Submit** the render to `POST /v3/hyperframes/renders`, yielding a `render_id`.
|
||
6. **Poll** `GET /v3/hyperframes/renders/{id}` until it completes or fails (skip with `--no-wait`).
|
||
7. **Download** the signed video URL to disk.
|
||
|
||
## Render options
|
||
|
||
| Flag | Default | Meaning |
|
||
| ---------------------- | --------------------------- | ------------------------------------------------------------------------------------------------------------------------------ |
|
||
| `--fps` | `30` | Frames per second, 1–240. |
|
||
| `--quality` | `standard` | `draft`, `standard`, or `high`. |
|
||
| `--format` | `mp4` | `mp4`, `webm`, or `mov` (webm/mov carry alpha). |
|
||
| `--resolution` | `1080p` | `1080p` or `4k` (4k billed at 1.5×). |
|
||
| `--aspect-ratio` | auto | `16:9`, `9:16`, or `1:1`. Auto from a local project's `data-width`/`data-height`; defaults to `16:9` for `--asset-id`/`--url`. |
|
||
| `--composition` / `-c` | `index.html` | Entry HTML file inside the zip. |
|
||
| `--output` / `-o` | `renders/<render_id>.<ext>` | Local download destination. |
|
||
|
||
```bash
|
||
npx hyperframes cloud render . \
|
||
--composition compositions/intro.html \
|
||
--output ./renders/intro.mp4
|
||
|
||
npx hyperframes cloud render --quality high --fps 60
|
||
```
|
||
|
||
`--resolution 4k` cannot combine with `--format webm`/`mov`: the 4k supersampling path has no alpha channel. Render 4k as mp4, or render alpha at native resolution.
|
||
|
||
## Templates and variables
|
||
|
||
Cloud rendering supports [variables](../SKILL.md#variables-parametrized--template-renders): declare `data-composition-variables` on the composition, then fill them at render time.
|
||
|
||
```bash
|
||
npx hyperframes cloud render --variables '{"title":"Q4 Recap","theme":"dark"}'
|
||
npx hyperframes cloud render --variables-file ./vars.json
|
||
npx hyperframes cloud render --variables '{"title":"Q4 Recap"}' --strict-variables
|
||
```
|
||
|
||
For a **local project** the CLI validates `--variables` against the declared schema _before_ uploading. For `--asset-id`/`--url` the schema lives server-side, so mismatches surface as a `hyperframes_project_invalid` API error.
|
||
|
||
**Upload once, re-render many** is the idiomatic template loop: render a local project to get its `asset_id`, then re-submit against that asset with new values (no re-zip, no re-upload).
|
||
|
||
```bash
|
||
npx hyperframes cloud render ./card-template # note the asset_id printed on upload
|
||
npx hyperframes cloud render --asset-id asst_abc123 --variables '{"name":"Ada"}'
|
||
npx hyperframes cloud render --asset-id asst_abc123 --variables '{"name":"Linus"}'
|
||
```
|
||
|
||
For high-volume personalized batches, the Lambda path adds a JSONL fan-out (see `lambda.md`). The full variables schema (types, declarative bindings, sub-composition overrides, precedence) lives in the `hyperframes-core` skill.
|
||
|
||
## Fire-and-forget and webhooks
|
||
|
||
By default the CLI blocks, polls, and downloads. Combine `--no-wait` (submit and exit with just the `render_id`) with `--callback-url` (HTTPS webhook on terminal status) for true fire-and-forget:
|
||
|
||
```bash
|
||
npx hyperframes cloud render --callback-url https://example.com/hf-hook --no-wait
|
||
# Poll later with: hyperframes cloud get hfr_def456
|
||
```
|
||
|
||
| Flag | Meaning |
|
||
| ----------------- | --------------------------------------------------- |
|
||
| `--no-wait` | Submit and exit immediately; print the `render_id`. |
|
||
| `--callback-url` | HTTPS webhook fired when the render terminates. |
|
||
| `--callback-id` | Opaque tracking ID echoed in webhook payloads. |
|
||
| `--poll-interval` | Poll cadence in seconds (default `10`). |
|
||
| `--max-wait` | Max poll duration in minutes (default `60`). |
|
||
|
||
## Managing renders
|
||
|
||
```bash
|
||
npx hyperframes cloud list # recent renders (--limit, --token, --all)
|
||
npx hyperframes cloud get hfr_def456 # full detail + short-lived signed video_url
|
||
npx hyperframes cloud delete hfr_def456 # soft-delete (--no-confirm to skip the prompt)
|
||
```
|
||
|
||
`video_url` and `thumbnail_url` are short-lived presigned URLs, so re-fetch with `cloud get` rather than caching them.
|
||
|
||
## Safe retries
|
||
|
||
The CLI transparently retries a `401` by force-refreshing the OAuth token and replaying. That's harmless for reads, but the zip upload (`POST /v3/assets`) is **not** idempotent: a blind retry creates a duplicate asset and bills twice. Pass `--idempotency-key` so retries are safe:
|
||
|
||
```bash
|
||
npx hyperframes cloud render . --idempotency-key "$(uuidgen)"
|
||
```
|
||
|
||
The key is forwarded to both upload and submit (the server scopes idempotency per-endpoint, so reusing one value is safe). Use any opaque string in `[A-Za-z0-9_:.-]`, 1–255 chars.
