2. MBAPPÉ LIP-SYNC

Mbappé must naturally lip-sync to the vocals in the existing background song.
Synchronize his mouth movements as accurately as possible with the actual vocal timing, lyrics, phonemes, and rhythm of the original audio.

Requirements:
- Accurate vocal-to-mouth synchronization
- Natural jaw and lip movement
- Appropriate mouth shapes for spoken or sung phonemes
- Subtle, realistic facial movement
- No exaggerated mouth movements
- No random talking
- No delayed or drifting lip-sync
- No mouth distortion
- No facial identity changes during singing

Preserve Mbappé's identity and facial structure during every mouth movement.
Do NOT replace, remix, regenerate, mute, or otherwise modify the original background audio. Keep the existing audio completely unchanged.

3. CAR SWAP

Replace the two existing cars with the two car reference images supplied with the editing materials.
Existing Car 1 → Provided Car Reference 1
Existing Car 2 → Provided Car Reference 2

Use each car's corresponding reference image as the exact visual design reference.

Preserve each reference car's:
- Exact model and design
- Body shape and proportions
- Dimensions and silhouette
- Paint color and finish
- Wheels and tires
- Windows and lights
- Grille, trim, and distinctive design elements
- Visible interior details

Place both replacement cars in the exact positions and orientations of their corresponding original cars.

Preserve the original:
- Perspective and scale
- Camera-to-car relationship
- Reflections and environmental lighting
- Shadows and road contact
- Motion, movement, and motion blur
- Occlusion and depth relationships

The cars must look naturally integrated into the original footage.
Do NOT modify the road, environment, background, camera, or surrounding objects.
Do NOT mix the designs of the two cars or allow either car to change model, color, or shape between frames.

4. PLAYING CARDS — COLOR CHANGE ONLY

The playing cards already present in the original video are correct.
Use the exact cards from the original footage. Do NOT replace, regenerate, or redesign them.

ONLY change the colors of Card #2 and Card #4.
Card #2 → Change its color only.
Card #4 → Change its color only.
Every other card → Leave completely unchanged.

Preserve the original cards' exact:
- Shape and dimensions
- Thickness and perspective
- Texture and material
- Graphics and symbols
- Typography and markings
- Card backs and borders
- Animation and movement
- Position, rotation, and orientation

Apply the color changes as realistic recoloring of the original card surfaces, preserving the existing design, shading, highlights, shadows, reflections, texture, and material properties.
The new colors must remain stable across all frames and follow the original cards' lighting and perspective.
Do NOT introduce new graphics, symbols, patterns, borders, or visual elements.
Do NOT change the color of any card other than Card #2 and Card #4.
If the intended target colors are specified separately, use those exact colors. Do not arbitrarily recolor other cards.

Preserve:
- Original scene and environment
- Background and surroundings
- Camera angle and movement
- Framing and composition
- Lens perspective
- Lighting and shadows
- Reflections and atmosphere

- Relative positions of objects and characters
- Spatial relationships
- Interactions between elements
- Timing and choreography
- Physics and natural motion
- Original background audio, voice, music, and sound design

Do NOT introduce new camera angles, pans, zooms, cuts, or scene transitions.
Do NOT replace or alter the background environment, walls, trees, sky, or props.
Do NOT alter the pacing, choreography, gestures, or duration of the scene.
Do NOT regenerate elements that do not require replacement.
