    test(producer): refresh hdr-feature-stack with real HDR/SDR clips

    frostbyte_neo 发布于 2026-04-19 21:12:01 +00:00

    Expands the regression composition to better cover the SDR-opacity
    fix and to read more clearly when reviewing the rendered output:

    • Replace the previous 36-byte placeholder media (Git LFS pointers
      that were never resolved on disk) with real BT.2020 PQ clips
      drawn from a YouTube HDR demo (M8hv1Oah2uQ) and BT.709 SDR clips
      drawn from a YouTube SDR sample (SnUBb-FAlCY). Total ~40 MB of
      binaries — kept inline rather than tracked through LFS so the
      fixture matches the rest of the hdr-regression suite.
    • Add data-start / data-duration to every HUD slate, caption,
      and overlay element so they actually reach the layered compositor
      during their owning scene window. Without these the elements were
      computed off-stage by the renderer and the slates / pip captions
      in scenes 1 and 2 never appeared in the final video.
    • Paint scene 6 on a white field so an opacity yoyo on a framed clip
      is visible — on the default near-black root the dip-to-translucent
      reads as no change at all.
    • Drop opacity from the scene-6 transform yoyo on #s6-f3. Earlier
      scenes already cover the opacity-yoyo path; scene 6 is now a
      dedicated transform showcase (entry opacity fade-in stays so the
      clip enters cleanly).
