Miguel Ángel 8e1ea7adc2 feat(studio): marquee selection, AE presets, per-keyframe ease + velocity fitting
Marquee selection: click+drag on empty canvas draws a dashed selection
rectangle. All elements whose OBB intersects are group-selected via
SAT. Shift+marquee adds to selection. Click on empty deselects.

Per-keyframe easing: each keyframe segment has its own ease, editable
via expandable bezier curve editor in the Animation panel. Parser
preserves per-keyframe ease through round-trips (ease-only updates
preserve existing properties).

AE Easy Ease presets: correct After Effects bezier values (0.333, 0,
0.667, 1) in the preset grid.

Velocity-based curve fitting: gesture recordings analyze velocity
profile and assign per-keyframe custom eases automatically.

Gesture smoothing: Gaussian-weighted moving average (from PR #1658)
+ easeEach support for keyframed tweens + fetch-cancellation race
fix in useGsapAnimationsForElement.

npm install -g hyperframes

Or use directly with npx:

npx hyperframes <command>

Commands

init

Scaffold a new Hyperframes project from a template:

npx hyperframes init my-video
cd my-video

preview

Start the live preview studio in your browser:

npx hyperframes preview
# Studio running at http://localhost:3002

npx hyperframes preview --port 4567

render

Render a composition to MP4:

npx hyperframes render ./my-composition.html -o output.mp4

lint

Validate your Hyperframes HTML:

npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json      # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose   # Include info-level findings

By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.

compositions

List compositions found in the current project:

npx hyperframes compositions

benchmark

Run rendering benchmarks:

npx hyperframes benchmark ./my-composition.html
