* feat(core): add gentle ramp-in, ramp-out and slow-mo-middle speed presets Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(studio): add voice, look and crop clip-menu items and clip badges Voice and Look are single-choice submenus writing data-fx-chain and data-color-grading; None clears. Crop opens the canvas crop preset bar. ClipBadges reads the live preview node and follows attribute edits. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(studio): drop the unstyled badge classes Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(studio): add crop aspect presets to the canvas crop handles Free, 16:9, 9:16, 1:1, 4:5, Reset and Done float above the clip opened from the clip menu. Presets commit a centred inset clip-path; Reset removes it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * refactor(studio): read the committed crop from the inline clip-path Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(studio-server): add freeze-frame file mutation Extracts the frame under the playhead with ffmpeg (media time honours data-media-start, playback rate and a rate lane) into assets/freeze/, then in one write splits the video, inserts a 2 s <img> still with the video's box styles, shifts the rest of the track and splits a data-link partner. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(studio-server): import replaceFileAtomically from core atomic-file Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * feat(studio): add freeze frame to the clip menu Freeze frame on a video under the playhead posts the studio-server freeze-frame mutation and records its before/after as one undo step. onFreezeFrame is threaded through the timeline edit callbacks. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(studio-server): keep the freeze still inside assets/freeze The clip id from the project HTML went straight into ffmpeg's -y output path, so an id with ../ segments wrote outside the project. The id is now reduced to one safe filename component, the output is pinned inside assets/freeze before extraction, and the still's src is built from that name rather than from a filesystem path. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * fix(studio-server): give every freeze still its own immutable name Two clip ids that sanitise alike (a.b / a_b), ids sharing an 80-character prefix, or a second freeze of one clip at the same playhead all produced the same still path, and ffmpeg's -y replaced the first still's pixels. The name now carries a hash of the raw id and a per-extraction token, the route refuses a name that already exists, and ffmpeg runs with -n so it can never overwrite. The freeze media time reads data-playback-start before data-media-start, as playback does.

@hyperframes/studio
Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

What it does
The studio is a React application with:
- Visual timeline — drag, resize, and arrange elements on tracks
- Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
- Live preview — see changes in real time as you edit
- Composition inspector — view and modify element properties
Development
The studio is embedded in the hyperframes preview command. To develop the studio UI itself:
cd packages/studio
bun run dev # Start Vite dev server
bun run build # Build for production
bun run typecheck # Type-check
