高对比几何节奏秀

Make a dynamic 15-second motion graphics video that shows off everything you can do as a motion designer. Treat it like the showreel for a job you really want. Go all out: something moves every second, big type, bold color, real camera moves, no slow fades.

16:9, 1920x1080, 30 fps. Build it as one HTML file where every frame is a pure function of time, then render every frame with Playwright and stitch them into an MP4 with ffmpeg.

Do not ask me any questions. Just build it and give me the MP4.
