Reference Image 1 = primary visual reference. Use this as the main source for the start frame, composition, framing, train placement, city layout, lighting, atmosphere, and overall steampunk world design. The generated video must begin with a frame that matches Reference Image 1 as closely as possible. Reference Image 2 = motion storyboard reference. Use this as the motion guide for timing, train positions, speed relationships, and the progression of the one-take shot. Create a 15-second cinematic video in one continuous shot. IMPORTANT: The shot must stay visually consistent with Reference Image 1. The result must feel like a direct animation of the original image, not a redesigned scene. No cuts, no shot changes, no scene resets, no time skips, no change of location. Scene: A vast steampunk city at dusk, filled with warm glowing lights, layered monumental architecture, bridges, canals, mist, and distant airships. On the left side of the frame is the exterior side of the camera train, with dark windows and carriage details clearly visible. The tracks run forward into the center depth of the frame. On the right side is the glowing canal city with bridges, rooftops, and dense illuminated buildings. The atmosphere is moody, cinematic, misty, and warmly lit. Camera setup: The camera is physically fixed to the left-side train, as if a passenger is filming forward from the outside of the train window. The camera and the left train move together at exactly the same speed. The camera must remain attached to the left train at all times. No floating camera, no detached motion, no drifting away from the train. Core direction rule: The camera train is always moving forward INTO THE DEPTH OF THE FRAME, toward the vanishing point. It must never appear to move toward the viewer. It must never slide backward. The sense of forward travel must be obvious through strong parallax in the rails, lamp posts, railings, bridges, canal edges, and city structures. Start frame requirement: At the very start of the video, the composition must closely match Reference Image 1. The oncoming train is already visible from the start on the opposite track, in the middle distance ahead. Do not remove the oncoming train from the start frame. Motion timeline: 0.0–1.5 sec: Start from a frame closely matching Reference Image 1. The camera is fixed to the left train. The left train moves forward into depth. The oncoming train is already visible ahead on the opposite track. The city on the right and the rails show natural parallax. 1.5–3.0 sec: The oncoming train approaches very quickly. It is a full train with multiple cars, not just a single engine. By around 3 seconds, the front engine of the oncoming train is already reaching the camera position and beginning to disappear past the near foreground edge, while the following cars continue behind it. This speed relationship is important. 3.0–8.0 sec: The passing moment continues. The engine has already passed, and multiple cars of the oncoming train continue streaking by on the opposite track. These cars briefly block much of the right-side city view. Keep the motion physically coherent and consistent with the original scene. The camera remains fixed to the left train and keeps moving forward into depth during the entire passing sequence. 8.0–12.0 sec: The last cars of the oncoming train recede and disappear behind the camera. The right-side city view opens up again. The tracks ahead are clear. The camera train continues moving forward into the depth of the frame. The world, composition, and lighting remain consistent with Reference Image 1. 12.0–15.0 sec: While still moving forward with the left train, the camera slowly pans to the right. This pan must be smooth and gentle. Reveal more of the glowing cityscape on the right: the canal, bridges, rooftops, lights, and towering architecture. The forward motion continues during the pan. End the video in the same continuous shot, with no cut. Train logic: The left train is the camera train and stays on the left side of the frame throughout. The oncoming train runs on the opposite track. The oncoming train must have multiple cars clearly visible during the approach and passing sequence. The timing must feel fast and natural: the oncoming engine reaches and passes the camera by around 3 seconds, then the rest of the cars continue to pass. Visual style: Highly cinematic, realistic steampunk, rich detail, dusk lighting, warm glow, atmospheric haze, wet metal rails, deep city scale, elegant bridges, canal reflections, monumental architecture, subtle motion blur during the passing train, realistic perspective and motion. Audio: Environmental sounds and sound effects only. Train wheels, rail clatter, steam, wind, metallic rumble, city ambience, and loud passing train sounds. No music. No background music. No dialogue.
