Create a calm, seamless 15-second ambient background loop using the reference image as the exact composition and location master. The camera is completely locked. Preserve the exact room, furniture, decorations, carpets, colors and object positions. Nothing moves. Animate only the lights. CENTRAL LIGHT INSTALLATION: The large curved installation must remain illuminated throughout the entire video. It must NEVER switch off completely. At least 95% of its bulbs must remain visibly illuminated at all times. Create only a few sparse, irregular lighting events during 15 seconds: • Around 2.5 seconds, one isolated bulb slowly fades completely off over about 0.5 seconds. It remains off briefly, then slowly returns to its normal brightness. • Around 5.5 seconds, two widely separated bulbs located in different rows slowly fade completely off. They return independently at different moments. No neighboring bulbs are affected. • Around 8.5 seconds, the entire installation gently dims only slightly, from 100% to approximately 75–80% brightness. Every bulb remains visibly glowing. The installation then slowly returns to full brightness over approximately 2 seconds. • Around 12 seconds, two other isolated, widely separated bulbs slowly fade completely off and then return independently. No more than two individual bulbs may be completely off at the same time. Never turn off an entire row, arc or section. Never create darkness across the whole installation. All brightness changes are soft and gradual. The timing is irregular and calm, with long stable pauses. No rapid flashing, no hard cuts, no strobe effect, no chasing sequence, no moving wave, no synchronized rows and no peacock-tail pattern. Each selected bulb behaves independently. FLOOR LAMPS: Each floor lamp performs exactly one slow off-and-on cycle during the entire 15-second clip. Around 4 seconds, the left floor lamp gently fades completely off, remains dark for approximately 0.5 seconds, then gently returns to full brightness. Around 11 seconds, the floor lamp beside the bookcase performs the same single cycle. The two floor lamps never dim simultaneously. No sparks, no rapid blinking and no repeated flickering. Keep the room’s overall exposure stable. Lighting changes produce only subtle, physically natural local changes on nearby surfaces. No global exposure flicker, no camera movement, no object deformation, no new objects and no people. The opening and final frames must match: all lights at their normal brightness. Clean sharp 4K image, detailed carpets, controlled highlights, no noise, no grain and no generated audio.
