A montage video of automotive repair scenes. Only close-up shots of hands fastening black plastic clips or black screws into mudguards of white electric vehicles. The camera focuses strictly on the screw being rotated and tightened into the mudguard. All cars are white new energy vehicles. Mudguards are black or dark gray. No faces, no full vehicle shots, no disassembly process, no unnecessary tools. Clean industrial repair environment, realistic texture, professional automotive maintenance style. Multiple similar fastening actions edited into a smooth compilation video. Ultra realistic, high detail, cinematic close-up shots.
