# CES style instruction — B03 Device Showcase

You are an experienced motion designer and video editor working in Claude Code. Apply the **B03 Device Showcase** technique to the supplied footage as specified below.

**B. Project configuration:** 1080×1920, 9:16, 30 fps · Source video: not provided — ask the user for the path before starting · Video language (on-screen text & captions): English

**Animated B-Roll** — The capture is mapped onto the screen of an unbranded device that moves like a product-film hero shot: a slow turntable rotation, a rise-and-settle or a tilt into frame, with a light sweep across the glass and a contact shadow beneath. It presents the app as a finished product rather than a raw recording, while the screen content stays exactly as captured.

### B03 Device Showcase

- **When:** ≈ 00:00.00 → 00:04.00 (≈ derived — adjust to the nearest natural beat in the footage)
- **Layer / track:** V1 (main picture)
- **What it does:** A supplied app capture plays inside a neutral phone, tablet or laptop that turns, rises and catches a soft glass reflection on a clean set.
- **Parameters:** Device: Phone; Device motion: Slow turntable; Max rotation: 22 deg; Glass reflection sweep: on; Background colour: #14161B; Rim light colour: #779CFF; Easing: Ease in-out (smooth)
- **Steps:**
  1. Cut to a device cutaway from 00:00.00 to 00:04.00 on a clean #14161B set with a soft radial pool of light behind the device.
  2. Build a phone (19.5:9 screen, ≈ 46% of frame width, 12% corner radius, thin dark bezel) as a neutral, unbranded frame — no real manufacturer shapes, logos or notches. Build only from the supplied assets — do not invent details, text, UI, numbers or features that are not present in them.
  3. Map the supplied screen recording onto the screen exactly (Remotion: <OffthreadVideo> inside the rounded screen element; for 3D poses use CSS perspective ≈ 2160px, or FFmpeg perspective/corner-pin). Keep its native aspect — letterbox inside the screen rather than stretch or crop away UI.
  4. Motion: rotate on Y from −22° to +11° across the whole range with a smooth ease-in-out curve (cubic-bezier(0.65, 0, 0.35, 1)), never stopping completely.
  5. Add one glass reflection: a 20° diagonal white gradient band (0 → 14% opacity, screen blend) sweeping across the screen over 33 frames, starting once the device has settled.
  6. Add a #779CFF rim light on the device edge facing the light (1–2px, 60% opacity) and a soft contact shadow beneath it (multiply, 35%) that tightens as the device settles. Verify the screen content stays sharp at every angle; reduce rotation if text smears.
- **Assets:** Screen recording (⚠ MISSING) · optional: Screenshots, Brand logo
- **Fallback:** With only a still screenshot, place it on the device screen and add a slow 6–10% internal scroll so the screen is not frozen. If 3D transforms are unavailable, use a frontal device with a gentle 2D scale and rise only.

**G. Asset integrity and restrictions:**
- Do not create or present invented testimonials, comments, quotes, reviews or endorsements.
- Do not fabricate numbers, metrics, charts or results. Data visualisations use only the supplied data.
- Do not create fake screenshots or UI and present them as real. Illustrative graphics must be clearly illustrative.
- Do not attempt unsupported 3D reconstructions or perfect subject separation without a mask; use the documented 2D fallbacks instead.

**I. Quality verification:**
- Check output dimensions and aspect ratio with ffprobe — they must match the configuration exactly.
- Check the output frame rate and that the duration is within ±0.5 s of the target.
- Check audio/video synchronisation at the start, middle and end (lip-sync and SFX hits within 1 frame).
- Inspect frames at every beat boundary for text clipping, overflow and safe-zone violations.
- Confirm the output file exists and plays — never claim a render is complete without an actual output file.
- Report any missing asset or unimplemented effect explicitly.
