WARDROBE AND SUNGLASSES LOCK, FROM THE FIRST FRAME THROUGH THE LAST: Mauvis on the LEFT wears the orange, blue and white vertically striped short-sleeve shirt OPEN over a PLAIN WHITE COTTON CREW-NECK T-SHIRT. The white undershirt has a simple round ribbed neckline, with NO pointed dress collar, NO buttons and NO necktie. The striped outer shirt remains visibly worn over the white crew-neck undershirt throughout every shot, including closeups. Do not turn the entire outer shirt white. Use Image 1 only for Mauvis's clean-shaven facial identity and short black hair; do not copy its formal white shirt, dress collar or tie. Mauvis wears the source left performer's WHITE-FRAMED SUNGLASSES with dark lenses throughout. Mark on the RIGHT wears the source orange knit polo and black shorts, and BLACK-FRAMED SUNGLASSES with dark lenses throughout. Do not copy the tuxedo or bow tie from Image 2. Both pairs of sunglasses fit their faces naturally, stay opaque and stable on the nose and ears through head turns, and never vanish or change color. Their mouths remain unobstructed. Keep these two outfits and sunglasses completely consistent for all ten seconds. Create a photorealistic replacement performance of exactly the supplied ten-second Video 1, retaining its orange studio, suspended silver microphone, original camera angles and cuts, screen positions, wardrobe, gestures, pacing, and original soundtrack timing. Image 1 is the identity reference for Mauvis, replacing ONLY the performer on the LEFT wearing the vertically striped orange, white and blue shirt. Use Mauvis's actual facial proportions, skin tone, short textured black hair, hairline, and clean-shaven face from Image 1. Mauvis has smooth clean-shaven cheeks, jaw and chin: no beard, no goatee, no heavy stubble, and no white chin whiskers. Do not copy the original performer's facial hair. Image 2 is the identity reference for Mark, replacing ONLY the performer on the RIGHT wearing the orange knit polo and black shorts. Use Mark's actual facial proportions, skin tone, short black hair and clean-shaven appearance from Image 2. The photos supply identities only: retain the source performers' wardrobe and stage blocking, not the photos' clothing or backgrounds. Keep the two identities distinct and on their assigned sides throughout every cut. Their own short hair replaces the original performers' long hair, and both wear their assigned sunglasses at all times while their mouths remain clearly visible for lip sync. Video 1 is the exact local time reference from 0.00 through 10.00 seconds for this section. Match each performer's mouth shapes, vocal turn-taking, breaths, head movement and expressive hand gestures to the corresponding performer in Video 1 at the same local time. Use the soundtrack embedded in Video 1 unchanged: same voices, same lyrics, same instrumental, same rhythm and timing, with no added or rewritten words. The person whose source counterpart is singing performs those precise syllables; the other mirrors his own counterpart's backing responses and rests. No time stretching, delayed singing, invented performance, new camera moves, titles, subtitles, or transitions. Natural facial anatomy and teeth, coherent hands, stable clothing textures, consistent skin tone under warm studio lighting. Preserve the source's editing rhythm and finish at exactly the reference endpoint so this section cuts directly to the next section. Both Mauvis and Mark have subtly more muscular, athletic physiques: slightly broader shoulders, fuller upper arms and forearms, a firmer chest and natural athletic proportions. Their shirts drape realistically over these modestly stronger builds. Preserve their recognizable faces, natural neck proportions, heights, full range of motion, wardrobe and exactly timed performance.
