Sora提示词：A hyper-realistic cinematic video of a single US dollar bill

A hyper-realistic cinematic video of a single US dollar bill lying flat on a pure black seamless studio background. Top-down view only. The camera is completely static. The dollar bill is shown in full, then a small realistic flame starts burning from one corner and quickly spreads across the entire bill. The burning process is slightly sped up, like a fast but smooth time-lapse. The paper curls and shrinks with highly detailed charring edges, glowing embers, tiny sparks, and thin dark smoke rising. Pieces of burnt paper break off and turn into ash, until the dollar is fully consumed and becomes a scattered pile of gray ash on the black background. High resolution, very detailed paper and fire texture, realistic fire and smoke simulation, cinematic look, clean minimal composition, no text, no hands, no people, no other objects, about 6–8 seconds.
