@hanzo/frame is taken by the hero video primitive — one full-bleed video element — which has held that name on npm since it shipped. This repo is the video toolchain: a CLI, a renderer, a studio, a player. Plural is what it is, so the CLI publishes as @hanzo/frames and the workspace packages follow it (@hanzo/frames-core, @hanzo/frames-engine, and the rest). The binary stays `frames`, and now actually ships. The manifest mapped it to bin/frames.mjs while the file on disk was bin/hyperframes.mjs, so a global install produced no working command. The paths that name a package to fetch were pointing elsewhere. The update check read registry.npmjs.org/frames, a different author's package, and the npm, bun and pnpm installers would have pulled it over the CLI; the render image installed the upstream hyperframes; scaffolded projects and the docs pinned the unscoped name. All of them now name @hanzo/frames.
HDR Regression Suite
HDR10 (BT.2020 PQ) regression suite with four back-to-back windows (A–D) covering the highest-value HDR compositing shapes. 10s / 300 frames at 30fps.
Windows
| # | Window | Pipeline aspect under test |
|---|---|---|
| A | Baseline HDR + direct opacity | HDR pass-through with a GSAP opacity tween directly on the <video> element. |
| B | Z-order sandwich (DOM → HDR → DOM) | Orange background, HDR video in the middle, blue overlay on top. Tests z-ordered layer compositing. |
| C | Transform + border-radius | HDR <video> with transform: rotate() scale() + border-radius clipping. Tests affine blit pipeline. |
| D | Shader transition (HDR → HDR image) | Shader transition between an HDR video and an HDR PQ image. Tests HDR image transfer cache + shader path. |
Fixtures
src/hdr-clip.mp4— short HEVC Main10 / BT.2020 PQ clip with a moving bright gradient (seeNOTICE.mdfor attribution). Reused across windows A–G and as scene A of the window-H shader transition.src/hdr-photo-pq.png— 256×144 16-bit RGB PNG with a hand-injectedcICPchunk (primaries=BT.2020, transfer=SMPTE ST 2084, matrix=GBR, range=full). Used as scene B of the window-H shader transition.
ffmpeg is not used to generate the PNG because it does not embed cICP
in PNGs — without that chunk Chromium would not treat the file as HDR and the
test would silently fall back to SDR.
To regenerate the PNG fixture (deterministic, byte-for-byte stable):
python3 packages/producer/tests/hdr-regression/scripts/generate-hdr-photo-pq.py
Running
cd packages/producer
bun run test:regression hdr-regression
bun run test:regression:update hdr-regression
In CI it runs in the hdr shard alongside hdr-hlg-regression
(see .github/workflows/regression.yml).
