Vance IngallsandClaude Opus 4.8 5aca3ad770 fix(studio): suppress shadow-parity false positives in timing + text (#1508)
runShadowTiming: compare start/duration with a relative epsilon (1e-6)
instead of exact equality so float-precision drift (3.1 vs
3.0999999999999996, 21.36 vs 21.360000000000014) no longer flags; a real
difference (3.1 vs 3.5) still flags. trackIndex stays exact.

property:text resolver: trim both sides (snapshot.text is already trimmed)
and collapse empty-string vs absent (null) text so trailing-whitespace and
empty-vs-null no longer flag. Genuine text differences are unaffected; the
per-keystroke length lag is a caller-side debounce concern.

Adds tests for both fixes plus regression tests documenting two REAL SDK
divergences the shadow correctly surfaces (transform-origin removal no-op;
duplicate-bare-id delete resolution) — flagged, not fixed here.

@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
