Seedance 2.0 余烬点燃磨损电线 抽象特效提示词

Extreme macro on a single ember crawling along a frayed cord against pure black. Frame opens black; at 1 second one ember glows to life, ignites, and travels laterally — slow-motion sparks lifting and dying, a thin spiral of smoke curling, individual carbon fibers glowing white-hot then blackening and folding. Builds to a small bright flare near 12 seconds, settling to a single glowing tip. The ember is the only light source — self-illuminated hot orange against absolute black, hard chiaroscuro. Camera tracks the spark with a tight micro push-in. Color palette: pure black and incandescent orange with a white-hot core — minimal, maximum dynamic range. Audio: low ominous drone, dry crackle and hiss of burning, a single sub-bass pulse.
