i made 10+ motion videos with opus 5.5 in 3 days. here's the whole pipeline (open source)

The author's pipeline: one seek(t) HTML file captured by headless Chromium, a beat map, four stills before the full render, summed closed-form springs, motion blur from eight subframes averaged in ffmpeg, drops found by measuring bass energy, sound effects placed on their peaks, and a scored contact-sheet critique. Packaged as a Claude Code skill.

Disclosure Maker's own products: the MIT-licensed claude-motion-design skill (howseen-ai) and the author's SaaS, Howseen, plugged at the end.
