TASK: Ultra-realistic video-to-video car interior replacement. SOURCE VIDEO: Original smartphone recording inside a Kia. IMAGE 1: BMW M5 G90 interior reference from the driver's perspective. MAIN GOAL: Replace ONLY the Kia interior with a photorealistic BMW M5 G90 interior. The final video must look like the SAME person recorded the SAME footage inside a real BMW M5 G90, at the SAME location and time. Everything except the car interior must remain identical to the source video. BMW INTERIOR: Use Image 1 strictly as the interior design reference. Recreate: - Authentic BMW M5 G90 steering wheel and BMW emblem. - Red M1/M2 steering wheel buttons. - BMW curved digital instrument cluster and infotainment screen. - Correct BMW M5 dashboard and center console. - Black premium leather with red accents. - Realistic carbon fiber trim and stitching. - Blue-violet ambient interior lighting. - BMW door panels, air vents and controls. Preserve the exact driver's perspective and original camera angle. The BMW interior must have accurate proportions, stable geometry, realistic materials and natural reflections. IMPORTANT: Image 1 has a white background outside the windshield. NEVER use or reproduce this background. Use ONLY the original exterior from the source video. EXTERIOR PRESERVATION — CRITICAL: Keep the original road and everything visible through the windows COMPLETELY UNCHANGED. Preserve exactly: - Road, asphalt and road markings. - Buildings, trees and vegetation. - Traffic signs and surrounding vehicles. - Sky, weather and natural daylight. - Original driving speed and direction. - Original scenery movement and perspective. Do not generate a new location, road or environment. The exterior must match the original video frame by frame. CAMERA — ORIGINAL SMARTPHONE STYLE: Preserve the original handheld smartphone recording appearance. Maintain exactly: - Camera position, framing and movements. - Natural handheld shaking and rotations. - Original exposure, white balance and colors. - Original sharpness and digital sensor noise. - Natural smartphone motion blur. - Original compression and autofocus behavior. - Original video duration and timing. DO NOT add cinematic color grading, film grain, artificial blur, camera stabilization or professional commercial effects. This must look like a REAL smartphone video, not a CGI advertisement. LIGHTING AND MATERIALS: Match all BMW interior lighting to the original daylight. Natural shadows across the steering wheel and dashboard. Realistic reflections on leather, carbon fiber, metallic surfaces, glass and displays. Authentic leather pores, stitching, material imperfections and subtle surface textures. No plastic-looking materials, artificial HDR or excessive sharpening. INTERIOR CONSISTENCY: All BMW elements must remain visually identical throughout the entire video. No steering wheel deformation. No changing dashboard geometry. No flickering screens. No unstable BMW logo. No floating buttons. No morphing surfaces. No distorted reflections. AUDIO — ABSOLUTE PRESERVATION: Keep the ORIGINAL audio track completely unchanged. Preserve the exact human voice, spoken words, pronunciation, intonation, volume, timing and microphone characteristics. Keep all original road noise, background sounds and natural pauses. Do not regenerate, replace, translate or modify any speech. Do not add engine sounds, music, dialogue or sound effects. STRICT NEGATIVE INSTRUCTIONS: No Kia interior or logos. No changes outside the vehicle. No new roads or buildings. No changes to the driver's viewpoint. No camera movement changes. No CGI appearance. No artificial cinematic effects. No distorted interior. No flickering displays. No changed voice. No new audio. No subtitles. No watermarks. FINAL RESULT: A completely believable, ultra-photorealistic smartphone video recorded inside a BMW M5 G90. The ONLY modification is replacing the Kia interior with the BMW M5 G90 interior from Image 1. SAME ROAD. SAME LOCATION. SAME CAMERA MOVEMENTS. SAME DAYLIGHT. SAME VIDEO TIMING. SAME ORIGINAL AUDIO. SAME PERSON FILMING. CHANGE THE INTERIOR ONLY. PRESERVE EVERYTHING ELSE.
