黄油升温融化实验

生成一段20秒、16:9的电影感微距延时视频：一小块黄油置于透明耐热皿中，温度从室温逐渐升至60°C。使用固定机位和清晰的实验室风格照明。展示黄油从坚硬不透明，逐渐变软、边缘圆润，随后变得有光泽并部分融化，最后在60°C时成为顺滑的金黄色液体，并保留少量柔软残块。全程保持皿、背景、构图和光线一致，突出真实的受热质地变化、细微表面光泽和连续的延时运动。不要出现人物、文字、标志，也不要使用源视频或音频输入。

【English Prompt】
Generate a 20-second 16:9 cinematic macro timelapse of a small pat of butter in a transparent heat-resistant dish as its temperature gradually rises from room temperature to 60°C. Use a locked-off camera and clear laboratory-style lighting. Show the butter progressing from firm and opaque, to softened with rounded edges, then glossy and partially melted, ending as a smooth golden liquid with a few soft remnants at 60°C. Keep the dish, background, framing, and lighting consistent throughout; emphasize realistic thermally driven texture changes, subtle surface sheen, and continuous time-lapse motion. No people, text, logos, source footage, or audio input.
