Opus 5.5 写代码生成 15 秒竖版动效广告
motion-studio 让 Opus 5.5 用代码写 15 秒竖版广告，无头浏览器截 900 帧、ffmpeg 合成，再自评打分到全项 8 分才出片。
A 15-SECOND MOTION AD RUNS $1,500 TO $3,000 AT A STUDIO. THIS HARNESS HAS OPUS 5.5 WRITE ONE AS CODE, THEN GRADE ITS OWN FRAMES LIKE A HARSH DIRECTOR. that clip is motion-studio, a harness built around opus 5.5 for one job: a 15s vertical reel with real UI in it. the model writes code, not pixels. → a headless browser walks the clock, 900 screenshots → ffmpeg stitches them into one mp4 → the soundtrack sets the timing, big moments land on downbeats two things are banned in its CLAUDE.md: a centered title on a gradient, and everything fading in together. then it grades its own frames: hook, legibility, motion, variety, sound sync, composition, brand. no full render until every score hits 8. round 1 had motion at 4. no timers. no css transitions. no Math.random. the last comment on the screen explains why it took three rounds.
