Kling 2.5 Turbo (pro)
Prompt video (Opal – strict, fără deviații): Realistic video. Fixed camera. A person wearing a grey striped sweater is assembling a wooden joint. Only the torso and hands are visible. The person is holding a metal hammer and gently tapping a horizontal wooden beam into a square mortise hole on top of a thick vertical wooden block. The wood is natural, light brown, with visible grain and no finish. The joint fits tightly as the hammer taps it into place. Lighting is soft and natural. Background is slightly blurred with green plants. No extra objects, no changes to the scene. Motion is slow and realistic: repeated light hammer taps, the wood gradually moving down into the joint. No stylization, no cinematic effects, no camera movement, no cuts, no added elements.
