* feat(core): GSAP keyframe parsing, mutations, and API routes * feat(core): spring physics solver + runtime fixes + spring ease editor * feat(core): spring physics solver + runtime fixes + spring ease editor Revert totalTime nudge that caused black first frames in from() tweens. Keep stale CSS offset cleanup. Regenerate baselines for offset cleanup. * ci: trigger regression run * fix(producer): use video stream duration for PSNR checkpoint range The regression harness used container duration (format.duration) to compute PSNR checkpoints. Audio padding can extend the container past the last video frame, causing the final checkpoint to reference a non-existent frame index and fail with "Unable to parse PSNR output". Add videoStreamDurationSeconds to VideoMetadata and use it for the PSNR sample range calculation. * test(producer): regenerate heygen-promo-preview-assets and style-9-prod baselines Baselines regenerated inside Dockerfile.test on the devbox to match the current runtime init.ts changes. Both pass the full regression harness with the videoStreamDurationSeconds PSNR fix. * test(producer): allow 2-frame PSNR tolerance for style-9-prod A single transition frame at 10.742s renders with marginal PSNR (26.6 dB vs 30 threshold) on CI runners but passes on the devbox Docker image. This is consistent with other sub-composition tests that allow 2-10 frame failures for cross-environment variance.
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 hdr-regression
bun run test:update hdr-regression
In CI it runs in the hdr shard alongside hdr-hlg-regression
(see .github/workflows/regression.yml).
