# CES style instruction — M02 Whip Transition

You are an experienced motion designer and video editor working in Claude Code. Apply the **M02 Whip Transition** 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

**Motion & Pace** — The outgoing shot accelerates sideways with heavy directional motion blur; at peak velocity the cut happens and the incoming shot decelerates into place from the same direction. Because the eye is following the motion, the cut becomes invisible and the change of scene feels energetic and continuous — a classic camera 'whip pan' recreated in the edit.

### M02 Whip Transition

- **When:** ≈ 00:14.83 (0.35 s) (≈ derived — adjust to the nearest natural beat in the footage)
- **Layer / track:** V2+ (overlay above the picture)
- **What it does:** Shot A whips out of frame in a streak of directional blur and shot B whips in from the same direction, hiding the cut mid-motion.
- **Parameters:** Direction: Left; Transition length: 10 frames; Motion blur strength: 70%; Shutter angle: 270 deg; Easing: Ease in-out (smooth); Settle overshoot: on
- **Steps:**
  1. At the cut boundary 00:14.83, build a 10-frame whip (333ms): 5 frames of shot A exiting and 5 frames of shot B entering, with the actual cut on the fastest frame.
  2. Shot A: translate left by ~648px (60% of frame width) accelerating with an ease-in; shot B: start 648px off the opposite side and decelerate to rest using a smooth ease-in-out curve (cubic-bezier(0.65, 0, 0.35, 1)). Both move in the SAME direction (left).
  3. Motion blur: horizontal only, shutter angle 270° — in Remotion use <CameraMotionBlur shutterAngle={270} samples={9}> around both layers; in FFmpeg approximate with a horizontal directional blur (e.g. dblur=angle=0:radius=18) peaking on the cut frame and falling to zero at both ends.
  4. Let shot B overshoot its resting position by ~2% of frame width, settling back within 4 frames.
  5. Overscale both shots to 1.04x during the whip so frame edges never reveal black; return to 1.00x within 3 frames after landing.
  6. Verify the cut does not split a spoken word: if needed, shift the boundary up to 4 frames to the nearest pause and keep dialogue audio continuous under the whip.
- **Assets:** Source video (⚠ MISSING) · optional: Second shot, B-roll footage, Sound effects
- **Fallback:** If both shots are static and very similar, a whip can feel unmotivated — use a simple hard cut or a mask swipe (M09) instead. If motion blur rendering is too slow, use a 3-frame tmix blend around the cut.

**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.
