**Duration:** 1.60s · **fps:** 25.0 · **size:** 800×450 · **codec:** h264

> 1.60s clip at 25.0fps, 800x450. 2 segment(s): hold, move. Dominant easing: ease-out. Profile: moderate visual complexity, moderate motion. Stagger hint: bottom-to-top (~99ms each).

## Motion-energy curve

Per-frame motion magnitude (mean pixel change vs previous frame). This is the source of truth for **timing and easing** — read the shape per segment rather than eyeballing frames.

## Segments (beats)

| # | kind | start | end | dur | easing | cubic-bezier | conf |
|---|------|-------|-----|-----|--------|--------------|------|
| 0 | hold | 0.00s | 0.40s | 0.40s | — | — | — |
| 1 | move | 0.44s | 1.56s | 1.12s | ease-out | `0.0,0.0,0.58,1.0` | measured |

**Dominant easing:** `ease-out`

**Stagger hint:** bottom-to-top — ~99ms between elements (confidence 0.98).

**Content profile (SI/TI):** moderate visual complexity, moderate motion

**Freezes/holds:** 0.0–0.4s, 1.32–1.32s

## Confidence

- **Measured** (reliable): duration, fps, segment boundaries, easing shape, stagger direction, holds/fades.
- **Visually estimated** (from the frames): which elements move, transform magnitudes (px/scale/rotation/opacity), colors, exact overshoot. Flag these as estimates when you build the spec.
