Miguel Ángel 2fe37e3406 fix(studio): a preview reload keeps a playing film playing where it was (#4438)
An edit that reloads the preview used to stop playback: the reload saved the
time, paused the live frame and marked the player paused, and the promoted
document started paused. Now forward playback runs on in the live frame while
the new document loads. At promotion the new document takes the live frame's
time, so playback, a stop at the end or a seek made during the load carries
over, and it keeps playing if the live frame was, unless the edit cut the film short of that time. A paused film, a reverse
shuttle and a dropped reload behave as before.

@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 19, Zustand 4/5 (state management; development uses Zustand 5)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
  • Phosphor Icons
