fix(render): make WebGL video textures deterministic in headless render (#1403)
* fix(render): make WebGL video textures deterministic in headless render WebGL compositions that sample a `<video>` as a texture (e.g. a faceted crystal with clips mapped onto its facets) rendered with flickering, non-deterministic facets: a video would intermittently show a stale frame or go black, and the same frame differed between two renders. Two gaps caused this: 1. No WebGL analog of the WebGPU `patchVideoTextureCompat`. Chrome's headless compositor can't feed decoded `<video>` frames to the GPU, so the engine injects a decoded `<img class="__render_frame__">` sibling per video each frame. The WebGPU `copyExternalImageToTexture` path substitutes it, but `texImage2D` / `texSubImage2D` did not — so WebGL uploaded a stale/black frame. Add `patchWebGLVideoTextureCompat()` mirroring the WebGPU patch (shared `resolveRenderFrameImage` helper). 2. Capture ordering. Per frame the runtime seeks (GPU adapters render on `hf-seek`) BEFORE the engine injects the decoded frames, so the GPU render read a frame that didn't exist yet. After injecting, the engine now calls `window.__hfReseekGpu(t)` — a force-dispatch (`forceDispatchSeekEvent`) that bypasses the same-time `hf-seek` dedup — so GPU compositions re-upload their textures from the freshly-injected, decoded frames, deterministically. Tests: unit tests for the texImage2D/texSubImage2D substitution and the force-dispatch, plus a videoFrameInjector regression test asserting the post-injection GPU reseek fires only when frames were injected. Verified end-to-end: a WebGL prism with 8 live <video> facets renders byte-identical across independent runs with no facet flicker. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(render): add producer render-compat regression for WebGL video textures A WebGL2 canvas samples a <video> as a texture every hf-seek (the natural author pattern, distilled from the HeyGen prism). The render-compat harness renders it and compares against the golden: with the video-texture fix the render reproduces the decoded frames; revert the fix and the canvas renders black, collapsing the comparison. Golden verified to contain real, time-varying video content (not black), so a regression is caught rather than passing vacuously.

fix(engine): harden ancestor-hidden video skip against mask + caller cache
Two follow-ups to the ancestor-visibility skip in `injectVideoFramesBatch`
and `syncVideoFrameVisibility`.
1. **Mask defence.** Both ancestor-hidden branches previously wrote a plain
`img.style.visibility = "hidden"`. `applyDomLayerMask` writes the
stylesheet rule `#${showId} *{visibility:visible !important}`, and CSS
cascade puts important stylesheet author above non-important inline
author — so a sub-comp host landing in the active layer's `show` set
would revive a stale `__render_frame__` and let it bleed onto the
layer composite. Write the hide via
`style.setProperty("visibility", "hidden", "important")` instead;
important inline beats important stylesheet.
2. **Caller cache hygiene.** `createVideoFrameInjector` unconditionally
wrote `lastInjectedFrameByVideo.set(id, frameIndex)` after calling
`injectVideoFramesBatch`, even for videos the page silently skipped due
to a hidden visual ancestor. On the next call at the same frameIndex —
common with source-fps < output-fps, paused source frames, or
non-frame-aligned host starts — the cache short-circuited the second
inject and the host's first visible frame painted blank because the
replacement `<img>` was never created.
Make `injectVideoFramesBatch` return `string[]` (the subset of ids it
actually painted) and have the caller cache only those. The cli-side
`snapshot.ts` consumer is unaffected: its local `InjectFn` types the
return as `Promise<void>`, which is structurally compatible with
`Promise<string[]>` under TS void-return assignment rules.
Tests: linkedom doesn't preserve `!important` in cssText, so the two new
mask-defence cases spy on the live `<img>`'s `style.setProperty` and assert
the 3-arg call shape. The cache-hygiene case stubs the page-side primitives
via `vi.mock`, drives the hook twice at the same frameIndex with a stubbed
"injected nothing" first response, and verifies the second call still
issues an inject. A counter-test pins the happy-path cache hit so a future
refactor can't trade the skip bug for a never-cache regression.

feat(studio): persist element positions in HTML, fix resize overlay drift and GSAP double-translation (#829)
* feat(studio): add pasteboard background to preview viewport Adds bg-neutral-800 to the preview viewport so the area outside the canvas is visually distinct from the composition content — consistent with professional video editors (Premiere, DaVinci, Figma). * feat(studio): pasteboard background and canvas outline around preview - NLEPreview: viewport gets bg-neutral-700 (#404040) as the pasteboard color surrounding the canvas — distinct from the app chrome (#0a0a0a) - Player wrapper: drop bg-black so the pasteboard shows around the canvas (loading overlays still cover the area with bg-black during load) - Player: set host background to transparent via inline style (overrides :host { background: #000 } in shadow DOM), and inject a style rule into the open shadow root so .hfp-container has overflow:visible and the canvas iframe gets a thin white ring + soft drop-shadow — making the canvas boundary legible against the pasteboard * feat(studio): disable manual positioning JSON by default, add toggle Manual edits were always stored in `.hyperframes/studio-manual-edits.json`, making it hard to share source without the sidecar file and easy to accidentally reposition elements via drag. Changes: - `enabled` field added to `StudioManualEditManifest` (defaults to `false` when absent — existing projects are unaffected until they opt in) - Drag handles, resize, and rotation handles are hidden when disabled - Layout X/Y/W/H/R fields in the Design panel are read-only when disabled - "Manual positioning" toggle added at the bottom of the Design panel, visible whether or not an element is selected - Toggle state is persisted to `.hyperframes/studio-manual-edits.json` so each project can opt in independently - `STUDIO_PREVIEW_MANUAL_EDITING_ENABLED` env flag still acts as a hard cap (env off → feature off regardless of project setting) * feat(studio): enable manual positioning by default (opt-out) * feat(studio): allow absolute elements to drag without toggle; gate JSON-backed drag behind toggle * feat(studio): persist positions directly to HTML; remove JSON sidecar and manual positioning toggle Replace the `.hyperframes/studio-manual-edits.json` sidecar with inline-style persistence baked directly into the HTML source. Drag/resize/rotation values are written as CSS custom properties (`--hf-studio-offset-x/y`, `--hf-studio-width/height`, `--hf-studio-rotation`) plus `translate`/`width`/`height`/`rotate` inline styles via `persistDomEditOperations` — no re-apply step needed on load. Key changes: - `sourcePatcher`: add `value: string | null` to `PatchOperation` — null removes the property/attribute from the HTML tag instead of setting it - `manualEditsDom`: add `build*Patches` / `buildClear*Patches` helpers that capture live element state into `PatchOperation[]` for HTML source writes; add `reapplyPositionEditsAfterSeek` (DOM-query-based seek hook, queries data-attribute markers) - `manualEdits.ts`: remove `applyStudioManualEditManifest` and all manifest target resolution; export `reapplyPositionEditsAfterSeek`; keep seek/play wrap infrastructure - `useManifestPersistence`: remove all JSON I/O — no disk read on load, no manifest state, no toggle state; `applyCurrentStudioManualEditsToPreview` now only installs seek hooks via `reapplyPositionEditsAfterSeek` - `useDomEditCommits`: replace `commitStudioManualEditManifestOptimistically` calls with direct DOM apply + `commitPositionPatchToHtml` (queued HTML patch write, skipRefresh) - `DomEditOverlay`: remove `manualEditsEnabled` prop; revert all `canMove || manualEditsEnabled` gates to just `canApplyManualOffset` — every draggable element is always draggable - `PropertyPanel`: remove `ManualPositioningToggle` component and all toggle props - `manualEditsParsing/manualEditsTypes`: remove manifest types, upsert functions, and `STUDIO_MANUAL_EDITS_PATH`; keep `finiteNumber`, `readStudioFileChangePath`, `roundRotationAngle`, and snapshot/CSS-property types * fix(studio): sync keyboard shortcut handler with main; fix keepPlaying seek assertions in test * fix(studio): strip GSAP-cached translate from transform on path offset apply * fix(studio): remove Reset edits button from design panel * feat(studio): wire reloadPreview into manifest persistence; drop stale group-selection refresh - Pass `reloadPreview` into `useManifestPersistence` so undo/redo reloads via the refresh-key path instead of directly touching the iframe. - Remove `refreshDomEditGroupSelectionsFromPreview` from commit handlers; HTML is now the source of truth so no stale-ref refresh is needed. - Add `manualEditsRenderScript` helper; export via studio-api and apply it in `htmlCompiler` during HTML compilation. * fix(studio): prevent root composition from being selected; correct overlay drift on resize - Guard `getDomLayerPatchTarget` against elements with `data-composition-id` so the root composition div is never returned as a visual selection target. - Apply the same guard to the raw `elementFromPoint` fallback in `getPreviewTargetFromPointer`, which was the actual escape path. - Thread `iframeRef` into gesture handler opts; after applying draft dimensions during resize, re-read the element BCR via `toOverlayRect` and update the overlay box position to compensate for visual drift on elements with centered transform-origin (e.g. GSAP scale tweens). * fix(studio): correct resize overlay for scaled elements; block invisible element selection - Resize: use BCR from `toOverlayRect` for both position and size after applying draft dimensions — GSAP scale makes visual size diverge from raw CSS size, BCR is the only accurate source during a gesture. - Click selection: add `isElementComputedVisible` guard to the `elementFromPoint` fallback so opacity-0 / autoAlpha-hidden elements cannot be selected even though the browser hit-test returns them. * fix(studio): reload preview on external file changes via SSE/HMR Share the app-level domEditSaveTimestampRef with useManifestPersistence so the SSE/HMR handler can suppress echoes from all studio saves (code tab, timeline, DOM edits), then call reloadPreview() for non-motion external changes that aren't echoes of our own saves. * fix(studio): suppress post-resize click to keep selection on resized element * fix(studio): serve registry blocks without index.html in preview Blocks ship as {id}.html + assets/ with no index.html. The preview route hard-coded index.html so these projects returned 404 and their assets (e.g. korea-map.png, map-nyc-paris.png) were never served. Add resolveProjectMainHtml() that falls back to {id}.html, thread the resolved compositionPath through transformPreviewHtml and injectStudioPreviewAugmentations, and update listProjects() in the vite adapter to surface block directories in the project list. * fix(render): preserve studio drag/resize/rotation offsets in rendered video Three issues caused studio-edited positions to be lost during rendering: 1. The seek-reapply script used setInterval to wrap window.__hf.seek, but Puppeteer's page.evaluate() calls don't yield the event loop for macrotasks — the interval never fired, so reapplyAll() never ran after GSAP seeks. Fix: use Object.defineProperty to trap writes to the seek property, wrapping it synchronously the instant the bridge assigns it. 2. MEDIA_VISUAL_STYLE_PROPERTIES (copied from <video> to proxy <img> during render) included "transform" but not "translate", "rotate", or "scale" — the CSS Transforms Level 2 individual properties used by studio drag/resize/rotation. The proxy was positioned at offsetLeft/ offsetTop without the translate offset. 3. getViewportMatrix (HDR compositor) only read cs.transform, missing individual transform properties entirely. Added composeIndividualTransforms to build the translate × rotate × scale matrix and compose it before the legacy transform matrix. * fix(studio): select elements with pointer-events: none in preview Compositions often set pointer-events: none on scenes, avatar wrappers, and decorative layers. elementsFromPoint() skips these elements entirely, making them unselectable in the Studio. Fix: temporarily inject a * { pointer-events: auto !important } stylesheet during hit-testing, then remove it immediately after. Also adds a pointer_events_none lint rule (info severity, visible with --verbose) so authors know which selectors may affect Studio selection. |

fix(hdr): filter zero-opacity elements and support overflow:hidden clip rects (#522)
* fix(hdr): filter zero-opacity elements and support overflow:hidden clip rects in HDR compositor
Two bugs in the HDR render pipeline:
1. Child data-start elements inside a parent with opacity:0 were still
composited as independent layers, painting over content in later scenes.
Fix: filter elements with effective opacity 0 before groupIntoLayers().
2. CSS overflow:hidden on ancestor elements was ignored for HDR video layers,
causing videos inside clipped containers (e.g. split-screen halves) to
render full-frame. Fix: add clipRect to ElementStackingInfo, compute it
from ancestor overflow:hidden in queryElementStacking(), and crop the
source buffer to clip bounds before blitting in blitHdrVideoLayer().
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(hdr): move opacity filter into blit loop to preserve hide-list correctness
The previous approach filtered zero-opacity elements before groupIntoLayers(),
which broke the DOM screenshot hide-list — invisible video elements' <img>
replacements weren't properly hidden from sibling layer screenshots, causing
the vignelli-stacking regression.
Fix: keep all elements in groupIntoLayers() for correct hide-list generation.
Skip zero-opacity HDR elements only during the actual blit step with an early
`continue` in the compositing loop.

* fix(hdr): route identity-matrix HDR elements through region blit for clip rect support
parseTransformMatrix returns a valid matrix even for untransformed HDR
elements (Chrome reports matrix(1,0,0,1,0,0)). This made the affine blit
path always run, bypassing the region blit path which is the only one that
applies clip rects from overflow:hidden ancestors.
Fix: detect identity matrices and route them through the region path so
the cropRgb48le clip logic is reachable for split-screen layouts.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(hdr): handle translation-only matrices for clip rect support
The previous isIdentity check only caught matrix(1,0,0,1,0,0). Elements
with layout translation (e.g. right-half split at left:960px reporting
matrix(1,0,0,1,960,0)) still routed through the affine path where clip
rects are not applied.
Fix: check for translation-only matrices (scale=1, rotation=0, any tx/ty)
and route those through the region blit path. el.x/el.y from
getBoundingClientRect already include the translation, so the region path
handles positioning correctly.

* feat(render): auto-detect HDR from media probes, add --sdr flag
Replace the --hdr opt-in model with automatic detection. When no flags
are passed, the renderer probes all video/image sources and enables HDR
output if any HDR color space is detected. Existing --hdr flag becomes
a force override. New --sdr flag forces SDR output.
Behavior matrix:
(no flags) + HDR content → HDR output
(no flags) + SDR content → SDR output
--hdr → force HDR (defaults to HLG if no HDR sources)
--sdr → force SDR (skips probing)
--hdr --sdr → error

fix(engine): stop clobbering native <video> opacity in HDR pipeline (#368)
## Summary Fix four interrelated bugs in the opacity pipeline. The headline fix: the HDR compositor was effectively ignoring direct-on-`<video>` opacity animation because the engine itself was clobbering inline opacity with `opacity: 0 !important` — switching to `visibility: hidden` resolves the bug at the root. ## Why `Chunk 1` of `plans/hdr-followups.md`. This was the most user-visible bug in the entire follow-ups list: a GSAP-controlled opacity tween directly on a `<video>` element under HDR rendered at full brightness instead of fading. ## What changed **1A — Stop clobbering native `<video>` opacity.** `screenshotService.injectVideoFramesBatch` and `syncVideoFrameVisibility` were applying `opacity: 0 !important` to native `<video>` elements to hide them under the injected `<img>`. That stomp clobbered any GSAP-controlled inline opacity, so the next seek read 0 from computed style and the comp went black. Switched to `visibility: hidden !important` only. Visibility hides the element from rendering without changing its opacity, so subsequent reads (and `queryElementStacking`) see the real GSAP value on every frame. The `parseFloat(...) || 1` recovery hack at `injectVideoFramesBatch` was specifically there to compensate for this stomp; it's now replaced with a `Number.isNaN` guard that defaults to 1 only when parsing actually fails. **1B — `Number.isNaN` guards in `queryVideoElementBounds`.** `parseFloat(style.opacity) || 1` silently coerced a real opacity of 0 into 1. Switched to explicit `Number.isNaN` checks so opacity 0 stays 0. Same fix for `parseFloat(style.zIndex)`. **1C — `instanceof HTMLElement` instead of cast.** `resolveRadius` cast `el as HTMLElement` to read `offsetWidth`/`Height`. SVG and other non-HTML elements would have crashed at runtime. Replaced the cast with an `instanceof HTMLElement` guard, and made the numeric fallback `Number.isNaN`-safe. **1D — Opacity walk starts from the element itself.** The walk in `queryVideoElementBounds` started from `el.parentElement` for HDR videos to skip past the engine's forced `opacity: 0` on the element itself. Now that the engine never sets opacity, the special case is unnecessary — always walk from `el`. Kept the `isHdrEl` lookup because transform/border-radius logic further down still branches on it. ## Test plan - [x] `bun run --filter @hyperframes/engine typecheck` clean. - [x] `bun run --filter @hyperframes/engine test` — 308/308 passing. - [x] `bun run --filter @hyperframes/producer typecheck` clean. - [x] `oxlint` + `oxfmt --check` on both touched files. - [x] `hdr-regression` Window C (the direct-opacity window) now passes against the regenerated golden — see follow-up PR in this stack which tightens the budget. ## Stack Chunk 1 of `plans/hdr-followups.md`. Window C of the regression suite documents the bug; the next PR in the stack regenerates the golden and tightens its `maxFrameFailures` budget. |

fix(cli): forward --hdr through Docker render + HDR docs (#346)
## Summary This PR ended up covering the full HDR Docker/docs follow-through plus the producer/engine work needed to make HDR still images render and regress correctly in CI. The branch now does four things: - forwards `--hdr` through the Docker render path in the CLI - adds and expands HDR documentation across the docs site - adds first-class HDR still-image support to the engine/producer pipeline - adds targeted HDR regression coverage, including a CI-safe fallback for PNG HDR metadata detection when `ffprobe` does not expose PNG color tags ## What changed ### CLI and docs - `hyperframes render --docker --hdr` now preserves `--hdr` when invoking the in-container CLI - added a dedicated HDR guide and linked it from CLI, producer, engine, rendering, and common-mistakes docs - documented HDR constraints and verification flow: HDR source requirements, MP4/H.265 Main10 output, PQ/HLG handling, Docker usage, and common SDR fallback causes ### Engine and producer HDR image support - added `ImageElement` support to the engine composition model and parsing path - threaded image elements through producer compilation and orchestration - probed image sources for HDR color spaces so image-only compositions can trigger HDR output without requiring an HDR video source - included HDR image start times in stacking queries so the layered compositor can place images correctly in z-order - integrated HDR image compositing into the layered HDR render loop alongside native HDR video layers and SDR DOM overlays - forced screenshot mode for HDR layered compositing where required to keep DOM/HDR layer composition deterministic - skipped readiness waiting for natively extracted HDR videos in the engine path where it was unnecessary and could block layered HDR flows ### HDR metadata robustness - added a fallback in `extractVideoMetadata()` to read PNG `cICP` metadata directly when `ffprobe` omits color-space fields for PNGs - this specifically fixes CI/Docker detection for the `hdr-image-only` fixture, where the render was falling back to SDR because the PNG was not being recognized as BT.2020 PQ ### Regression coverage and fixture cleanup - added `hdr-image-only`, a regression fixture that validates HDR still-image rendering end to end - added `hdr-pq`, a focused HDR PQ regression fixture for the video path - updated regression CI to run an `hdr` shard with `--sequential hdr-pq hdr-image-only` - removed the older larger `hdr-regression/*` fixture set in favor of the smaller targeted regressions used by CI - added the necessary fixture generation/readme material and checked-in golden outputs for the new HDR tests ## Why The original PR description only covered the CLI flag forwarding and docs work. Since then, the branch also picked up the missing runtime support needed for HDR still images and the regression coverage to keep that path from breaking. The practical issue this closes is: - local host runs could pass while CI failed `hdr-image-only` - the failure was a full-frame visual mismatch caused by SDR fallback, not unstable rendering - root cause was PNG HDR metadata not being surfaced by `ffprobe` in the CI Docker environment - parsing the PNG `cICP` chunk directly makes HDR detection deterministic across environments ## Test plan ### Local targeted checks ```bash bunx oxlint packages/engine/src/utils/ffprobe.ts packages/engine/src/utils/ffprobe.test.ts bunx oxfmt packages/engine/src/utils/ffprobe.ts packages/engine/src/utils/ffprobe.test.ts bun --cwd packages/engine test src/utils/ffprobe.test.ts src/utils/hdr.test.ts ``` ### Producer regression runs on host ```bash bun run --cwd packages/core build:hyperframes-runtime:modular bun --cwd packages/producer test -- --sequential --exclude-tags slow,render-compat,hdr bun --cwd packages/producer test -- --sequential hdr-pq hdr-image-only ``` Observed result: - `fast` shard: 7 passed, 0 failed - `hdr` shard: 2 passed, 0 failed ### CI-equivalent Docker verification ```bash docker build -f Dockerfile.test -t hyperframes-producer:test . docker run --rm \ --security-opt seccomp=unconfined \ --shm-size=4g \ -v "$PWD/packages/producer/tests:/app/packages/producer/tests" \ hyperframes-producer:test \ --sequential hdr-pq hdr-image-only ``` Observed result: - `hdr-image-only`: passed - `hdr-pq`: passed - shard summary: 2 passed, 0 failed ### Specific regression fixed Before the PNG `cICP` fallback, the Docker/CI run failed `hdr-image-only` with: - missing `"[Render] HDR source detected — output: PQ ..."` log line - full-frame visual mismatch across all 100 checkpoints - PSNR ~17 on every frame, indicating a consistent SDR-vs-HDR pipeline mismatch After the fallback, the same Docker path recognizes the PNG as HDR and the shard passes. |

feat(hdr): GSAP transforms and border-radius masks on HDR video (#290)
## Summary HDR video elements with GSAP animations (position, scale, rotation, opacity) and CSS border-radius rendered without any transforms applied — the video just sat at (0,0) full-size. This PR adds affine transform support and rounded-corner masking for natively-composited HDR video. ## What it does **Affine blit with bilinear interpolation:** - `blitRgb48leAffine()` — Takes a 4x4 DOMMatrix and maps each destination pixel back to source coordinates via the inverse transform. Bilinear interpolation between the 4 nearest source pixels produces smooth edges under rotation and non-integer scaling. Optional opacity and border-radius parameters. - `parseTransformMatrix()` — Parses CSS `matrix(a,b,c,d,e,f)` strings into `[a,b,c,d,e,f]` tuples. **Accumulated viewport matrix:** - `getViewportMatrix()` — Walks the `offsetParent` chain from element to viewport, accumulating position offsets and CSS transforms at each level. Correctly handles `transform-origin` using the CSS sandwich: `translate(origin) × M × translate(-origin)`. This is critical because GSAP animates transforms on wrapper divs, not directly on the video element. **Effective opacity:** - `getEffectiveOpacity()` — Multiplies opacity values walking up the ancestor chain. Uses `Number.isNaN()` (not `|| 1`) so opacity:0 isn't incorrectly treated as 1. **Border-radius masks:** - `roundedRectAlpha()` — Per-pixel anti-aliased rounded-rectangle mask with support for independent corner radii. - `getEffectiveBorderRadius()` — Walks ancestors for `overflow:hidden` + border-radius. Resolves percentage values (e.g., `50%` for circles) via `offsetWidth`/`offsetHeight`. **Layout dimensions for extraction:** - Uses `offsetWidth`/`offsetHeight` (unaffected by CSS transforms) instead of `getBoundingClientRect()` (which returns the transformed bounding box and wobbles under rotation). ## Files changed | File | What changed | |------|-------------| | `packages/engine/src/utils/alphaBlit.ts` | `blitRgb48leAffine()`, `parseTransformMatrix()`, `roundedRectAlpha()`, `cornerAlpha()` | | `packages/engine/src/services/videoFrameInjector.ts` | `getViewportMatrix()`, `getEffectiveOpacity()`, `getEffectiveBorderRadius()`, `layoutWidth`/`layoutHeight` on `ElementStackingInfo` | | `packages/producer/src/services/renderOrchestrator.ts` | Affine blit path, extraction at layout dimensions, border-radius parameter passing | ## How to test Render a composition with an HDR video that has GSAP scale + rotation animation and a `border-radius: 50%` wrapper (circle mask). The video should rotate smoothly with round edges — no wobble, no sharp corners. ## Stack position **5 of 6** — Stacked on #289 (z-ordered layers). Adds transform and masking support to the HDR blit that the layer compositor uses. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

feat(engine): add HDR two-pass compositing — DOM layer + native HLG video (#288)
## Summary Compositions with HDR video AND DOM overlays (text, graphics, SDR video) couldn't render both correctly — either HDR data was lost (Chrome captures sRGB only) or DOM overlays were missing (FFmpeg pass-through skips Chrome). This PR adds in-memory alpha compositing that combines both. ## What it does **Per-frame two-pass capture:** 1. **DOM pass** — Chrome screenshots the page with a transparent background (CDP alpha). HDR videos are hidden, leaving transparent holes where they go. 2. **HDR pass** — Pre-extracted native HLG/PQ frames (16-bit PNG from FFmpeg) are read from disk. 3. **Composite** — DOM pixels (sRGB RGBA8) are alpha-composited over HDR pixels (rgb48le) in Node.js memory, with sRGB→HLG/PQ conversion via a 256-entry lookup table. **Key components:** - `decodePng()` / `decodePngToRgb48le()` — Pure Node.js PNG decoders (no native dependencies). Support all 5 PNG filter types. - `blitRgba8OverRgb48le()` — Alpha composite with per-pixel sRGB→HDR LUT conversion. Fast paths for alpha=0 (skip) and alpha=255 (overwrite). - `initTransparentBackground()` + `captureAlphaPng()` — Split CDP transparent background setup (once) from per-frame screenshot capture (eliminates 2 CDP round-trips per frame). - Single-pass FFmpeg extraction — All HDR frames extracted in one sequential FFmpeg run (avoids duplicate frames from per-frame `-ss` fast seek). ## Key design decisions | Decision | Why | |----------|-----| | In-memory compositing (not FFmpeg overlay) | Eliminates ~2400 process spawns + temp files per render. Pure pixel math is 10x faster. | | 16-bit PNG intermediate | Raw `-f rawvideo` loses color metadata, causing moiré artifacts. PNG is self-describing. | | sRGB→HLG LUT (256 entries) | DOM content is sRGB. Without conversion, it appears orange-shifted in HLG stream. | | Native HDR detection before extraction | `extractAllVideoFrames` converts SDR→HDR. Pre-extraction probe identifies original HDR sources so only truly-HDR videos get native extraction. | ## Files changed | File | What changed | |------|-------------| | `packages/engine/src/utils/alphaBlit.ts` | **NEW** — PNG decode, sRGB→HDR LUT, alpha compositing (14 tests) | | `packages/engine/src/services/screenshotService.ts` | Transparent background CDP, `captureAlphaPng()` | | `packages/engine/src/services/videoFrameInjector.ts` | `hideVideoElements()` / `showVideoElements()` | | `packages/engine/src/services/streamingEncoder.ts` | Input color space tags for rgb48le | | `packages/producer/src/services/renderOrchestrator.ts` | Two-pass HDR capture loop, native HDR detection | ## How to test Render a composition with an HDR video background and text overlays. Both should be visible — HDR video at full quality, text crisp with correct colors (not orange-shifted). ## Stack position **3 of 6** — Stacked on #265 (HDR output pipeline). This is the foundation for all layered compositing that follows. 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

initial code (#2)
* feat: initial code port from hyperframes-internal Port all OSS-ready packages from the internal monorepo: - @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime - @hyperframes/cli — CLI for creating, previewing, and rendering compositions - @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg) - @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg) - @hyperframes/ui-player — browser-based video player component - @hyperframes/studio — composition editor (React frontend + Hono backend) Includes regression test suite with Docker-based test harness. All HeyGen-internal references, deployment infrastructure, and proprietary assets have been removed. Package names migrated from @app/* to @hyperframes/*. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: scrub internal codenames and stale references from OSS port - Replace static.heygen.ai runtime URLs in test fixtures - Remove internal CDN publish script (publish-hyperframe-runtime.ts) - Replace sandbox-studio, sandbox-interceptor, __magicEditRuntime with neutral names (studio, hyperframe-runtime, __hyperframeRuntime) - Fix stale Vault API / localhost references in docs - Remove broken deprecated_studio link Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: remove remaining internal codenames and stale references - Delete stale producer README.md and PIPELINE.md (referenced nonexistent files) - Replace "Cerberus" codename with "HyperFrames" in test design reviews - Replace magic-edit postMessage identifiers with hf-preview/hf-parent - Rename debug-magic-edit-timeline.ts to debug-timeline.ts - Replace "Motion Cut" with "HyperFrames" in Timeline comments - Fix studio/CLI references to nonexistent archive package (use local data/projects/ dir, stub render proxy) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |
