* feat(studio): element groups — source mutations Wrap/unwrap source mutations (group geometry, the wrap-elements / unwrap-elements routes) that the studio group feature is built on. Studio UI lands in the next PR. * fix(studio): hoverable group interior + non-sticky drill-in Two group selection bugs with animated members: 1) Empty space inside a group's overlay didn't hover/select the group. Members animated outside the wrapper's static box (110px box vs 340px member union), so elementsFromPoint hit only the full-bleed background there. Add a member-union hit-test fallback: a point inside a group's live member bounds resolves to that group (innermost wins). 2) After drilling into a group and selecting a child, nothing else was selectable — out-of-scope resolved to null. Make drill-in non-sticky: interacting outside the drilled group re-resolves normally and exits the drill-in, so a later click on the group selects it as a unit again. * feat(studio): enable animation editing for static inline timelines The unsupported-pattern banner now clears for static window.__timelines["id"] = gsap.timeline() (the parser reports it editable), and the banner copy is retargeted to the genuinely-unsupported case: computed/dynamic keys (window.__timelines[var]). * fix(studio): correct keyframes + expansion for sub-composition timeline clips Two gaps for elements inside a sub-composition: 1) Clip keyframes rendered off-clip. The keyframe cache computes clip-relative percentages from the element's start/duration, but sub-comp internals aren't in the timeline elements list, so duration defaulted to 1s and percentages blew past 100%. Resolve the timing basis from the sub-comp HOST's bounds (via domClipChildren, since the host's data-composition-src is stripped in the rendered DOM). Shared resolveClipTimingBasis used by both cache populators, which now re-run when the sub-comp children appear. 2) Only GROUPED sub-comp children expanded. Generalize the DOM-children collector to gather id'd children of the sub-comp inner-root (grouped OR ungrouped), descending through id-less structural wrappers; one level into groups for drill-in. Ungrouped pills now expand into timeline rows too.
@hyperframes/studio
Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.
Install
npm install @hyperframes/studio
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
Tech stack
- React 18/19, Zustand (state management)
- CodeMirror 6 (editor)
- Tailwind CSS (styling)
- Vite (bundler)
- Phosphor Icons
