## Summary
- Adds a hover tooltip (?) next to the format dropdown in the render queue export bar
- Shows the selected format's details (codec, use case) plus a comparison with the other two formats
- Helps users pick between MP4 (general), MOV/ProRes 4444 (transparent video for editors), and WebM/VP9 (transparent for web)
## Test plan
- [x] Open studio, go to the render queue panel
- [x] Hover over the (?) icon next to the format dropdown — tooltip appears above
- [x] Switch format in the dropdown — tooltip content updates to show the selected format first
- [x] Move pointer away — tooltip dismisses
- [x] Verify tooltip doesn't clip or overflow the panel

## Summary
Coordinated minor bump across all published packages. No source changes in this PR itself; it is the version stamp for everything that landed on main since v0.2.5.
## Version bumps
| Package | from | to |
|---|---|---|
| `@hyperframes/cli` | 0.2.5 | **0.3.0** |
| `@hyperframes/core` | 0.2.5 | **0.3.0** |
| `@hyperframes/engine` | 0.2.5 | **0.3.0** |
| `@hyperframes/player` | 0.2.7 | **0.3.0** |
| `@hyperframes/producer` | 0.2.5 | **0.3.0** |
| `@hyperframes/studio` | 0.2.9 | **0.3.0** |
Between 0.2.5 and this release, `player` and `studio` received several patch versions on npm as we iterated on the bundler, entry point, and SSR issues. 0.3.0 collapses that into a single coordinated minor so the ecosystem is aligned again.
## What is in v0.3.0
### `@hyperframes/player`
**Restored package entry points to the compiled `dist/` output.** 0.2.5 shipped with `"main": "./src/hyperframes-player.ts"` but the published tarball only included `dist/` via the `"files"` field. Every consumer trying to import the package failed with `Module not found: Can't resolve '@hyperframes/player'`. Entry points now point at the built JS/`.d.ts` files inside `dist/`.
**DOM-based root timeline resolution in the ready probe.** In a bundled preview, `window.__timelines` contains the master composition alongside its sub-compositions, for example:
```js
{
main: GSAPTimeline(14s),
intro: GSAPTimeline(1.5s),
'scene2-4-canvas': GSAPTimeline(12.6s),
'scene5-logo-outro': GSAPTimeline(3.2s),
}
```
The probe used to select the adapter with `keys[keys.length - 1]`. Object key ordering meant the last-registered sub-composition would win, so the `ready` event reported a sub-composition's duration (e.g. 3.2s) instead of the master's 14s. The probe now looks up the root composition id from the outermost `[data-composition-id]` element in the iframe DOM and uses its key. Falls back to the last key when no element is present, so standalone sub-composition previews keep working.
### `@hyperframes/studio`
**`useTimelinePlayer.getAdapter()` uses the same DOM-based root id lookup** as the player. Previously play, pause, seek, and duration readout were all driven by whichever sub-composition happened to register its timeline last.
**`Player.tsx` loads `@hyperframes/player` lazily.** The component used to call `import "@hyperframes/player"` at module scope, which runs the package's `customElements.define(...)` side effect during module evaluation. `HTMLElement` does not exist in the Node runtime, so any consumer page that transitively imported the studio during server rendering threw:
```
ReferenceError: HTMLElement is not defined
at module evaluation (@hyperframes/studio/src/player/components/Player.tsx)
```
The import now runs inside the mount effect via `import(...)` so it only evaluates in the browser. Added a cancellation flag and deferred cleanup so a fast unmount before the dynamic import resolves does not leak listeners or DOM nodes.
**Captions module imports stripped of `.js` extensions.** Files under `src/captions/` imported siblings as `./types.js` and `./parser.js`. That is legal ESM TypeScript but Turbopack and several other bundlers refuse to resolve those specifiers against `.ts` files inside `node_modules`, breaking any consumer build that transitively pulled in the captions module. Captions now uses extensionless imports, matching the rest of the studio codebase.
### `@hyperframes/core`, `@hyperframes/cli`, `@hyperframes/engine`, `@hyperframes/producer`
Version bump only, no source changes since 0.2.5. Kept on the same version so the ecosystem is easier to reason about.
## Impact for consumers
If you use `@hyperframes/studio` in a Next.js app:
- The play button in a bundled preview reports the correct composition duration and drives the master timeline.
- The session page no longer 500s in dev mode when the studio barrel is imported (the SSR fix).
- Turbopack builds that transitively load the captions module no longer fail on `Cannot resolve './types.js'`.
If you use `@hyperframes/player` directly:
- Consumer bundlers can resolve the package again (dist entry points restored).
- The `ready` event duration reports the master, not a sub-composition.
## After merge
Publish each package to npm with `pnpm publish` (workspace deps auto-resolve).
* fix(studio): load @hyperframes/player lazily to support SSR
Player.tsx had a bare `import "@hyperframes/player"` at module scope. The
player package registers a class that extends HTMLElement as a side effect,
and HTMLElement doesn't exist in a Node server runtime. Any consumer that
imported from @hyperframes/studio during server-side rendering (e.g. the
Next.js App Router evaluating a client component for SSR) threw
`HTMLElement is not defined`.
Move the import inside the mount effect via dynamic `import(...)` so it
only runs in the browser, and wire up a cancellation flag and deferred
cleanup so a fast unmount doesn't leak listeners or DOM nodes.
* fix(studio): remove .js extensions from captions-internal imports
The captions module imported sibling files as `./types.js` and
`./parser.js`. That's legal ESM TypeScript, but Turbopack (and other
bundlers) refuse to resolve those specifiers against .ts files when the
package is consumed from node_modules — the rest of @hyperframes/studio
uses extensionless imports for that reason.
Align captions with the rest of the codebase so the package builds
without bundler-specific configuration in consumers.
* chore: release @hyperframes/player@0.2.7 and @hyperframes/studio@0.2.9
Ships the root-timeline resolution fix (#247), the SSR-safe player load,
and the captions import cleanup.
Bundled previews register a master composition alongside its sub-compositions
in `window.__timelines`, e.g. { main, intro, scene2, scene5 }. Both the
player's probe and studio's getAdapter() were using `keys[keys.length - 1]`
to pick the adapter, which returned whichever timeline was registered last.
That made the player report the final sub-composition's duration as the
video length (e.g. 3.2s instead of the master's 14s) and play/pause/seek
targeted that sub-composition instead of the full composition.
Look up the outermost `[data-composition-id]` element in the iframe DOM
and use its id to select the right timeline. Falls back to last-key when
no element is present (standalone sub-composition previews) so drill-down
views keep working.
Also restores `main`/`import` entry points on @hyperframes/player to
point at compiled dist output (the src/ paths broke workspace consumers
that only receive the published tarball).
* fix(studio): support web-component refs in useTimelinePlayer
The studio's `useTimelinePlayer` hook returns an `iframeRef` that
consumers attach to an `<iframe>` element. When consumers wrap the
iframe in a custom element (e.g. `<hyperframes-player>`) that puts
the iframe inside its shadow DOM, every `iframeRef.current.contentWindow`
access returned `null` and `getAdapter()` silently failed — meaning
timeline seek, play, pause, and `refreshPlayer` all became no-ops.
Changes:
- Add `resolveIframe(el)` helper that returns the underlying iframe
whether the host is the iframe itself, a custom element with a
shadow-DOM iframe, or a wrapper with a descendant iframe.
- Export `resolveIframe` from the studio so consumers can pre-resolve
the iframe before assigning it to `iframeRef`.
- Internal `useTimelinePlayer` keeps the strict `HTMLIFrameElement`
ref type, so existing consumers attaching directly to an `<iframe>`
are unaffected.
Also adds:
- JSDoc on the player's `iframeElement` getter.
- "Advanced: iframe access" docs section in `packages/player/README.md`
and `docs/packages/player.mdx`.
- Type-safety lint rules in `.oxlintrc.json` and a "Type-safety
conventions" section in `CONTRIBUTING.md`.
Backward compatible — App.tsx and NLELayout.tsx continue to work
unchanged.
* chore(lint): defer no-explicit-any rule; it broke existing codebase
The new rules added 37 errors across 32 existing files — mostly
legitimate `window as any` casts at browser-global and test-mock
boundaries. Enabling them without fixing all violations breaks CI.
Revert the `.oxlintrc.json` additions and soften the CONTRIBUTING.md
wording to describe the convention without claiming lint enforcement
(that enforcement will come in a follow-up PR that fixes all sites).
## Summary
- **Replaces the studio's hand-rolled iframe + scaling in** **`Player.tsx`** with the `<hyperframes-player>` web component, eliminating duplicated ResizeObserver, dimension detection, and stage-size message handling
- **Adds a public** **`iframeElement`** **getter** to the player web component so the studio's `useTimelinePlayer` can still access the inner iframe for clip manifest parsing, timeline probing, and DOM inspection
- **Updates player package exports** to resolve from source for workspace consumers (matching `@hyperframes/core` pattern), while npm-published consumers still get built `dist/` files
### Why a separate player package?
1. **Zero dependencies, any framework** — 12KB vanilla web component vs 940KB React+Zustand+CodeMirror studio
2. **CDN-ready** — single `<script>` tag, no build pipeline needed
3. **Embeddable by third parties** — users embed compositions in their own sites without the studio
4. **Single source of truth** — studio now uses the player instead of duplicating its scaling/detection logic
## Test plan
- [x] `pnpm --filter @hyperframes/player typecheck` passes
- [x] `pnpm --filter @hyperframes/studio typecheck` passes
- [x] `pnpm --filter @hyperframes/studio build` passes
- [x] `pnpm --filter @hyperframes/studio test` passes (2 pre-existing failures, unrelated)
- [x] E2E: Standalone player loads composition, detects 4s GSAP timeline, controls work, play/pause works
- [x] E2E: Studio preview renders via `<hyperframes-player>`, `iframeElement` bridge works, playback controls sync correctly
## Summary
- The Vite dev server proxied studio renders to a separate producer server (port 9847) that needed to be started manually
- When the producer wasn't running, renders silently failed — red dot, no error message, no way to know what went wrong
- Replaced the proxy with direct in-process rendering via `@hyperframes/producer` — same code path as the CLI and embedded preview mode
- Removed ~70 lines of SSE proxy streaming code, replaced with the same ~20-line in-process pattern used everywhere else
## DX improvement
**Before:** `pnpm dev` + `npx tsx packages/producer/src/public-server.ts` (two terminals, easy to forget)
**After:** `pnpm dev` (renders work immediately)
## Testing
Verified manually: open studio via `pnpm dev`, navigate to a project, click Export — renders complete with live progress updates, no separate server needed.
## Summary
- Adds `--format mov` to the render CLI for ProRes 4444 transparent video output
- ProRes 4444 with alpha is the industry standard for transparent video overlays, supported by CapCut, Final Cut, Premiere, DaVinci, and After Effects
- WebM VP9 alpha technically works but is ignored by all major video editors — only browsers decode it
- Adds MOV to the studio export dropdown alongside MP4 and WebM
## Transparency format comparison
| Format | Codec | Alpha | Video editors | Browsers | File size |
| --- | --- | --- | --- | --- | --- |
| **MOV** | ProRes 4444 | Yes | CapCut, Final Cut, Premiere, DaVinci, After Effects | No (won't play in browser) | Large (~5-40 MB) |
| **WebM** | VP9 | Yes | None (shows black) | Chrome, Firefox | Small (~200 KB) |
| **MP4** | H.264 | No | All | All | Small |
> **Note:** ProRes MOV files do not play in Chromium browsers — they are an intermediate/editing format, not a delivery format. Use [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video) to verify transparency works correctly.
## Changes
- **CLI**: Add `mov` to `--format` validation, examples, and output path logic
- **Engine**: `getEncoderPreset()` returns ProRes 4444 (`yuva444p10le`) for `mov` format; handle `.mov` in `applyFaststart` and `muxVideoWithAudio`; add `pix_fmt` to streaming encoder ProRes path
- **Producer**: Treat `mov` like `webm` for alpha capture (PNG frames, screenshot mode, `forceScreenshot`)
- **Studio**: Add MOV option to export format dropdown and render queue hook
- **Core**: Add `mov` to studio API types, render route, and mime helpers
- **Tests**: Add encoder preset tests for mov format (42 total, all passing)
## Usage
```bash
hyperframes render --format mov --output overlay.mov
```
## Test plan
- [x] `pnpm build` passes
- [x] `pnpm --filter @hyperframes/engine test` — 42 tests pass (2 new for MOV)
- [x] `oxlint` and `oxfmt` clean on all 12 changed files
- [x] End-to-end local render produces ProRes 4444 (`yuva444p12le`) with working alpha
- [x] Docker render with `--format mov` — ProRes 4444 confirmed via ffprobe
- [x] Studio dropdown shows MOV option in built JS
- [x] Transparency verified with [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video)
## Summary
- **New skill:** **`marker-highlight`** — integrates [MarkerHighlight.js](https://github.com/Robincodes-Sandbox/marker-highlight) into HyperFrames compositions. Canvas-based animated text highlighting with 5 drawing modes: marker pen, circle, burst, scribble, and sketchout.
- **Studio fix:** added missing `captionSync` to useEffect dependency array (oxlint exhaustive-deps)
- **Studio fix:** `loadOverrides` now checks `res.ok` before parsing, preventing 404 console noise on projects without captions
## Skill details
The skill documents the non-obvious GSAP integration pattern discovered during development:
1. **One highlighter per container** — the library clears ALL `.highlight` divs from the shared parent on init, so multiple instances on sibling marks conflict
2. **`data-color`** **\+** **`data-original-bgcolor`** — prevents the CSS background-color flash that occurs when the library reads and clears the mark's background
3. **Canvas pre-draw + clear + reanimate** — `animate: false` pre-draws statically, canvases are hidden, then cleared and shown with `reanimateMark()` at trigger time for clean animated reveals
4. **`onReverseComplete`** **for rewind** — hides highlight divs when the timeline seeks backward past the trigger point
## Test plan
- [ ] `npx hyperframes lint` passes on test-composition
- [ ] Studio preview shows marker highlight on "something" at 1s, circle on "love" at 2.2s
- [ ] Rewind past trigger points hides highlights
- [ ] No 404 console errors for caption-overrides.json on non-caption projects

* fix(studio): address caption designer PR feedback
Fixes from review comments on feature/caption-designer (#180):
- fix(generator): guard named colors in hexToRgba — "red", "transparent"
no longer produce NaN rgba values
- fix(sync): log auto-save failures instead of silently swallowing them
- fix(sync): check res.ok before parsing caption-overrides response
- refactor(components): extract Section, Row, inputCls into shared.tsx
to eliminate duplication between CaptionPropertyPanel and
CaptionAnimationPanel
- fix(store): replace non-deterministic Date.now()+Math.random() ID with
counter-based group IDs
- fix(store): read selectedGroupId from state param instead of get() to
avoid stale reads in batched set() calls
- fix(overlay): remove cssScale multiplier from getBoundingClientRect

* fix(studio): address remaining caption designer feedback
Overlay: handle both per-word spans (generator output) and grouped text
nodes (existing templates). Wraps text nodes into individual spans on
demand so the overlay can target words in any caption format.
Property panel: add Typography (font, size, weight, spacing) and Color
(color, active, dim, opacity) sections alongside existing Position and
Transform controls.
Timeline: move caption timeline into a dedicated flex-shrink-0 section
below the main timeline tracks instead of inside the scrollable area.
Gives it fixed 60px height that's always visible.
Caption overrides: classify color tweens by comparing target color to
the dim baseline instead of relying on timeline position order. This
handles compositions with custom color tweens correctly.
App.tsx: remove polling interval, rely on runtime postMessage events
for caption detection. Add clarifying comment on why useEffect is
appropriate (external event subscription).

* fix(studio): restore cssScale in overlay coordinate conversion
getBoundingClientRect() on iframe-internal elements returns coordinates
in the iframe's native resolution (1920x1080), not the CSS-scaled
display size. The cssScale multiplier is needed to convert to parent
window coordinates. The earlier removal was incorrect — it only worked
at 1:1 scale.

* fix(studio): fix reversed scaling on left-side corner handles
Scale interaction used horizontal dx from start position, which goes
negative when dragging left handles outward. Now uses distance from box
center — dragging away from center increases scale regardless of which
corner handle is used.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(studio): make rotation respond to horizontal drag only
Rotation handle sits directly above the word, so atan2-based rotation
barely responds to left/right movement. Replace with linear horizontal
mapping: drag right = clockwise, drag left = counter-clockwise,
200px = 90 degrees. Vertical movement is ignored.

* feat(skills): add hyperframes-cli skill for CLI workflow guidance
Adds a new skill that teaches AI agents how to use the HyperFrames CLI
(init, lint, dev, render, doctor). Previously, agents had no way to
discover the CLI — the compose-video skill only covered HTML authoring.
This led to agents searching for binaries, finding the monorepo, and
running bun run studio manually instead of using npx hyperframes dev.
Also registers the skill in init.ts so new projects get it bundled
alongside hyperframes-compose and hyperframes-captions.

## Summary
The timeline is now hidden by default. A toggle button appears in both the header (alongside panel toggles) and the player controls bar. Both sync the same state and turn teal when the timeline is visible.
## Changes
- **`timelineVisible` state** in `App.tsx`, defaults to `false`
- **Header toggle**: icon button between sidebar toggle and Renders button
- **Player controls toggle**: icon button at the right end of the controls bar
- **NLELayout**: `timelineVisible` and `onToggleTimeline` props gate the timeline + resize divider
- **Player controls stay visible**: moved from inside the timeline section to inside the preview area, so hiding the timeline doesn't hide play/seek/timecode
## Behavior
| State | Preview | Player controls | Timeline |
|---|---|---|---|
| Timeline hidden (default) | Full height | ✅ Visible | Hidden |
| Timeline visible | Shorter | ✅ Visible | Shown with resize handle |
Both toggle buttons show identical teal active state (`#3CE6AC/10` bg + `#3CE6AC/30` border).

## Summary
Removes the `ProjectPicker` home screen entirely. The studio now boots directly into the editor by auto-selecting the first available project from `/api/projects`.
## Changes
- **Auto-select on load**: When no `#project/` hash is present, fetches the project list and navigates to the first one
- **Type narrowing**: Added `if (resolving || !projectId)` early return so TypeScript narrows `projectId` to `string` for all downstream props
- **Removed**: `ProjectPicker`, `ProjectCard`, `ExpandedPreviewIframe` components (~280 lines), `handleSelectProject` callback, `ProjectEntry` interface
## Why
The CLI studio always has exactly one project. The home page was an extra click with no value.

npm's sigstore provenance verification requires package.json
repository.url to match the GitHub repo. Without it, publish
fails with E422 "expected to match https://github.com/heygen-com/hyperframes".
The blank template was a bare `<div>` fragment without `<!DOCTYPE>`,
`<head>`, or `<body>`. This caused:
- Blank preview (bundler/runtime can't initialize from a fragment)
- "Failed to run lint" (parsing errors on the malformed document)
All other templates (swiss-grid, vignelli, warm-grain, play-mode) are
proper HTML documents — blank was the only outlier.
Also improves lint error reporting to show the actual error message
instead of the generic "Failed to run lint."
