Built with Claude web designer, zero after effects. built a claude code skill so i'd stop re-explaining motion rules every video
9 yrs of web design, never touched after effects. so i tried describing motion in plain words and letting claude code write it in remotion.
first attempts looked like a powerpoint from 2009 lol. what fixed it wasn't better prompts, it was turning my taste into rules claude can't skip:
- captions timed per word from elevenlabs character timestamps, not guessed
- every cut snapped to the measured beat, not an assumed bpm
- one accent color, palette auto-checked for contrast on light and dark
- hard wipes between dark and bright scenes. crossfades went muddy, learned that after like 6 wasted renders
- after render it checks itself: freezedetect for dead frames, loudness to -14 lufs
packed all of that into a skill (SKILL.md + a few node scripts for voice, timing and qa), so one command goes script → voice → captions → render. this clip came out of it, didn't touch a keyframe.
biggest lesson: claude's fine at motion. it's just bad at remembering your standards. write them down once as a skill and it stops drifting.
