Keep the exact camera framing, camera motion, and timing of the driving video unchanged. Preserve both actors exactly as they perform in the driving video: their faces, expressions, hair, wardrobe, head turns, hands on the wheel, and lip sync must not change or drift at any frame. Preserve the car body, dashboard, seats, steering wheel, mirror, and window trim exactly as in the driving video.

Replace only the area outside the car windows and windshield with the bright, sunlit, tree-lined city avenue shown in the reference image: clean mid-rise buildings, mature overhanging trees, utility poles, a few parked cars along the curbs. Match the reference image's look, color grade, and warm sunlit daytime atmosphere exactly. The environment beyond the glass is out of focus with a shallow depth of field, clearly softer than the actors, who stay sharp.

The sun is strong and directional from SCREEN-RIGHT: the screen-right side of the street is warm and sunlit, the screen-left side is in cooler shadow, and the sky is brightest toward screen-right. This matches the light already on the actors, whose brighter side is screen-right. Do not flip, flatten, or invent a contradictory light direction at any frame.

Preserve the moving shadows that already play across the actors' faces -- do not add new shadows that are not already on their faces, and do not remove the ones that are. The street is lined with dense trees, poles, and close buildings on the screen-right (sunlit) side, so their shadows sweep across the actors repeatedly as the car passes -- position the environment geometry so these passing shadow-casters line up with the shadow dips already in the plate.

Throughout the shot the car is driving at a normal, steady city speed: the background moves past at a fast, consistent parallax matching real driving footage through a car window, with closer objects (parked cars, poles, trees) streaking past faster than distant buildings, with motion blur. The car keeps driving at the same speed for the whole clip -- it does not slow down or stop.

Add subtle reflections of the street on the windshield and side glass, brighter on the screen-right side, shifting with the camera, faint enough that the actors stay clearly visible.

Do not add pedestrians, moving vehicles, or new people anywhere. Do not add text, signage, or license plates. No camera cuts, no reframing, no change to shot length.
