Video Editing · Seedance prompt cases

Video editing: remove everyone in @video1 except the protagonist.

Hyper-real cinematic realist style with photorealistic live-action texture, emphasizing the real-world plausibility of the physical object bursting out (the steam train); no CGI gloss / game engine / stylized 3D. Preserve @video1's original composition, projection-hall lighting, handheld camera state and natural imperfections. Source video locked: keep @video1 fully intact as the base image (the old-fashioned projection hall, the rows of hat-wearing audience seen from behind, the projector's conical beam, the screen, the ambient light, the color tone and the handheld movement all unchanged); the only additions: the train bursting out of the screen, the changes in light and shadow it brings, the tearing of the screen, and the slight physical impact on the hall and the front-row audience. Color-shift rule (the core addition): at the start strictly keep @video1's original black-and-white old-film texture (grain / scratches / flicker / monochrome); at the exact moment the locomotive truly breaks through the screen and bursts into reality, the image abruptly shifts from black-and-white to full, real color, the color spreading across the whole frame like a shockwave centered on the point where the train breaks out (the train's black steel body, the red-copper boiler, the orange-yellow steam-lamp glow, the warm brown of the wooden carriage, the white-grey steam, and the warm brown of the projection hall all coming into color accordingly); the color shift is precisely synchronized with the screen-breaking burst, after which photorealistic color is maintained to the end. Screen-tearing locked: the screen is a real white projection cloth with genuine fabric tension; as the train bursts out it is forcibly torn open along the contour of the locomotive's front, with radial rips whose edges curl back and shredded cloth fibers flying. Subject: an old-fashioned steam locomotive front bursting forcibly out of the screen, a black steel body, a cylindrical boiler, a front cowcatcher, a chimney venting white-grey steam, a bright headlamp, the metal surfaces with real wear, oil grime, rivets and wet reflections, charging forward with immense weight and inertia. Camera: fully inherits @video1's original handheld movement, not smoothed, not re-timed, not re-composed; the bursting train stays correctly locked into the screen and the hall space at all times, maintaining correct parallax, occlusion and ground-contact shadow. Sound: no music, keep only real on-scene sound effects, inheriting @video1's projection-hall ambience (the projector's clatter, the audience's stirring) and adding the sound of the cloth tearing, steam gushing, the mechanical roar of steel wheels, and the impact air blast. Total duration exactly the same as @video1; add nothing other than the train itself and its physical interactions, the screen tearing, and the color shift at the moment of the break. No slow motion, no sense of magic, no stylized horror; the final result should look like an eerie yet real image of "a train smashing through the screen, black-and-white instantly turning to color" captured by chance by a real camera in an old projection hall.
