Create a 5-second cinematic, photorealistic supernatural mystery video based directly on the reference image. The fluffy white cat and golden retriever are the two main characters. Preserve their exact appearance, fur color, body proportions, relative size, and identity from the reference image. SCENE: A dark abandoned mansion hallway at night. The hallway has old dark wooden paneling, aged walls, warm candle sconces, a worn red carpet, a hanging chandelier, an old open doorway, and many large framed portraits lining both walls. The white cat and golden retriever are standing together in the middle of the hallway beneath the portraits. The staircase is visible in the distance. IMPORTANT: The people in the portraits are the only human figures in the scene. They remain inside their frames throughout the entire video. No real people appear in the hallway. No additional animals appear anywhere in the scene. CAMERA: Use the same low cinematic perspective as the reference image. Keep both animals clearly visible in the lower foreground and keep the framed portraits on both walls clearly visible. Use a very subtle forward camera movement. No cuts and no sudden viewpoint changes. TIMELINE: 0–1 seconds: The white cat and golden retriever slowly walk forward together along the hallway. All of the people in the framed portraits remain completely still. The candles flicker naturally. 1–2 seconds: As the animals move forward, the person in the large portrait on the right side of the hallway slowly moves only his eyes and looks directly toward the two animals. His body remains completely still inside the painting. The movement is subtle but clearly visible. 2–3 seconds: The golden retriever suddenly notices that the portrait is looking at them. The dog stops walking and slowly turns its head toward the right-hand portrait. The white cat also looks toward the same portrait. 3–4 seconds: Now the person in a large portrait on the left side slowly turns his head toward the animals. The figure remains completely inside the frame and does not leave the painting. The golden retriever looks from the right portrait toward the left portrait. 4–5 seconds: The white cat and golden retriever look at the two portraits for a moment, then slowly turn their attention toward the dark staircase at the end of the hallway. End with both animals staring toward the staircase while the portrait figures remain watching them. CHARACTER BEHAVIOR: The golden retriever is cautious and slightly unsettled when it realizes the portraits are moving. The white cat is curious and observant rather than frightened. The animals remain together throughout the scene. The supernatural effect should feel mysterious and restrained rather than frightening. VISUAL STYLE: Photorealistic cinematic animation, realistic fluffy fur, natural animal movement, detailed old mansion interior, aged wooden panels, antique framed portraits, warm candlelight, deep shadows, atmospheric dust particles, worn carpet, and subtle supernatural effects. The portrait figures should look like realistic old painted portraits. Their movement should be extremely subtle and uncanny. Only their eyes or head move. Their bodies, clothing, hands, and frames remain completely still. AUDIO: Quiet old mansion ambience. Soft paw steps on the carpet. Gentle candle flickering and faint room ambience. A subtle low supernatural tone begins when the first portrait moves its eyes. A faint wooden creak accompanies the second portrait turning its head. No dialogue. No comedic sound effects. The visual story must remain understandable even if no audio is generated. CONTINUITY AND CONSTRAINTS: The white cat and golden retriever remain the same animals throughout the entire video. The people in the paintings never leave their frames. No human figure physically enters the hallway. No additional animals appear. The right portrait moves first. The left portrait moves second. The portrait bodies remain static while only their eyes or heads move. The animals react only after noticing the portrait movement. The candles remain lit and stable. The hallway remains physically unchanged. The staircase remains empty. Do not create shadows that resemble animals or people outside the portraits. Do not create black cats, dark animals, ghosts, monsters, or humanoid figures in the hallway. No blood, violence, attacks, or jump scares. No animal transformation, duplication, morphing, teleportation, or sudden scene changes. No cuts. The final frame clearly shows the two animals looking toward the mysterious staircase while the portraits continue watching them.
