}Um resultado real do Kling 2.5 Turbo
Early morning in Lisbon. Two men in their late twenties, a couple, race each other on old city bicycles down a steep empty cobbled street between tiled houses; the one in front looks back laughing and the other stands on the pedals to catch up, a yellow tram waiting at the bottom of the hill. Tracking shot from just ahead of them, warm low sun, wind in their shirts.
