Carlos Alcaraz GregorandCarlos Alcaraz 0c0cccec96 fix(studio): preserve playback across forward RAF loop wrap-around (#1103)
When forward playback reaches loopEnd and the loop wraps back to
loopStart, the RAF tick was calling `adapter.seek(loopStart)` without
keepPlaying, then immediately `adapter.play()` to resume. With the
post-3e7b464b wrapTimeline contract (default seek pauses), this means
every loop boundary executes pause→seek→pause→play for GSAP and a
stop/start RAF ticker cycle for the static-seek adapter — purely
unnecessary churn.

Pass { keepPlaying: true } so seek skips the implicit pause; the
follow-up adapter.play() is then a no-op because the underlying
adapter never paused. Adds two tests covering the wrap-around branch
(previously uncovered) and the no-loop terminal path as a regression
guard.

Completes the keepPlaying rollout: #842 introduced the option for A/E
shortcuts, #863 extended it to the runtime player, #1089 aligned the
static-seek adapter, and this applies it to the last internal caller
that explicitly resumes after seek.

@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
