captions.js

• Fixed: the browser overlay no longer rebuilds the scene every frame while the video is paused (0 rebuilds when nothing changes; rebuilds on seek, resize, preset/captions change, font load). getRenderCount() for diagnostics.
• Renamed: style.aplifiedWordColor → style.highlightColor. The old name is deprecated but still read when highlightColor is absent, so saved settings keep working. New helper getHighlightColor(settings).

@captionsjs/server

• Dropped fluent-ffmpeg (deprecated, printed an npm warning on every npx captions.js burn); ffmpeg/ffprobe are spawned directly.
• Rotation of phone videos is read from the display matrix, as modern ffprobe reports it.
• pnpm previews renders every preset with the engine (mp4, webm, poster, manifest.json, gallery page). Published to GitHub Pages at /presets/.

Repo

• CI: build + tests on Node 20 and 22 for every PR.

captions.js

• Fixed: bounce and underline animations were frozen in their end state (easeFn(1)). Bounce now pops in over 150 ms with a slight overshoot and pushes neighbouring words aside by exactly the growth of the active word (no overlap at any scale); underline draws in over 250 ms. Zero-length words no longer produce NaN.
• Fixed: exports now carries types for both import and require, verified under bundler, node16 (ESM + CJS), nodenext and node10 resolution.
• Added: getPreset(name) (case-insensitive, throws with the list of names) and presetNames.
• Added: npx captions.js burn <video> <words.json> — launcher for @captionsjs/server.
• Removed: renderCaptions(ctx, text) — a docs demo stub (red 48px text), never a real renderer. Use renderFrame / renderStylePreset.
• Removed: postinstall script (broke --ignore-scripts, flagged by audits).
• Removed stray console.log calls from library code.
• License file added; the project is MIT.

@captionsjs/server (first public release)

• Publishable package: burnCaptions() Node API + captionsjs CLI.
• Accepts plain word timings, Whisper verbose_json and Deepgram responses.
• Fonts come from Google Fonts on demand (cached in ~/.cache/captionsjs/fonts), so the 57 MB of TTFs stay out of the npm tarball. --fonts-dir for offline use.
• Font scale now follows the browser rule (videoHeight / 480), so the burned-in file matches the preview. The legacy Pub/Sub /burnCaptions job keeps scale: 1.
• Raw RGBA frames into FFmpeg instead of PNG per frame; output fps follows the source.
• Dropped the canvas (node-canvas) dependency — skia-canvas does all the drawing.
