Perform a high-quality video-to-video transformation based on the provided inputs. Inputs provided:
@video1 — A video featuring a person opening a door and walking through it.
@image1 — A visual reference image showing the specific world/environment that should appear behind the door.
Instructions:
Preserve from @video1: The exact appearance, identity, gender, face, haircut, and clothing of the person. Keep their physical actions, body physics, the precise timing of opening the door, the walking path, and the camera's original movement (including natural handheld shake or motion blur) completely identical to the source video.
Change from @video1: Completely replace the original environment, room, or background that is revealed once the door is opened.
New Environment: The space behind the open door must be transformed into the exact world shown in the @image1. The art style, textures, colors, and atmosphere of this new world must perfectly match the Reference Image.
Interaction: As the person opens the door and steps forward, they must seamlessly cross the threshold and enter the new world. The lighting on the person's body and clothing must realistically adapt and shift to match the lighting conditions of the world from the @image1.
Output Requirements: A smooth, continuous video. Maintain absolute character consistency. Keep the original background audio and Foley from the source video, layered with subtle atmospheric sounds matching the new environment.
