Miguel Angel Simon Sierra 5e3ca6ae63 feat(studio): drag a clip past the video end to extend its duration
Dragging a timeline clip (or its right resize edge) past the end of the
video now extends the composition duration on drop, instead of clamping
the clip at the current end. Extend-only and undoable.

- Relax the move/resize horizontal clamps that pinned a clip's end at the
  current duration; effectiveDuration now folds in the active drag/resize
  preview so the ruler and track width grow live as you drag past the end.
- On drop, extend the root composition data-duration (and the store) when
  the clip's new end exceeds it, via a shared extendRootDurationInSource
  helper extracted from the block installer (now the single owner of that
  logic). An extending edit routes through the server persist path since
  the SDK setTiming op can't express the root composition's own duration.

@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)
