Release v0.2.18 · hypit-ai/hypit

Highlights

Frame animations of later Presents render at the right time again. Since 0.2.15, a lifecycle motion (for example enter: fade) on an Item that starts after frame 0 was evaluated at absolute composition time, so the Item skipped its fade or stayed invisible for most of its window. Animations now follow their own Present's time, as in 0.2.13. (#373, fixes #372)
Still-image clips keep their colors. Pictures turned into video are now converted with the BT.709 matrix and tagged, so players no longer shift the colors of HD still clips. (#363)
Alpha sources normalize about 9x faster. The lossless VP9 encode for video with transparency now runs at libvpx's fastest speed. Decoded frames are identical. (#383, fixes #382)
hypit media fetch works with TikTok. The locked yt-dlp environment now includes curl_cffi, so yt-dlp can impersonate a browser. (#384, fixes #381)
Frame-boundary errors surface before Build. A Timeline end or Take at that does not land on a whole frame (for example end="8s" at 30000/1001 fps) is now reported by hypit check when the Clock is static (#355, fixes #354). hypit plan also reports any Producer failure in a step that carries no request, and exits 1 instead of calling the plan valid (#348).

Install @hypit/hypit@0.2.18. Existing video projects and materials need no migration.

If you have already run hypit media prepare-fetch, run it once more so the prepared environment picks up curl_cffi.

hypit.cli-plan@1 output gains producerFailureCount, present on every plan, and producerFailures, present when it is non-zero.

CI passed on Linux and Windows for the release candidate on main.
