Can Claude Make Videos? I Had It Draw This One in JavaScript
I saw a TikTok about making videos with JavaScript, dropped it into Claude, and told it to update my skills and make this one. Every frame is code: one function takes a moment in time and draws one picture, a headless browser renders every frame, Claude checks the frames for mistakes, and ffmpeg stitches them into the video.

0:00Every single frame of this video is JavaScript.
0:02I didn't draw any of it, and I never opened After Effects.
0:05Claude Code wrote it.
0:07It writes one function where you give it a timestamp, and it draws whatever's supposed to be on screen at that exact moment.
0:13Ask for that twenty four times a second and you've got a video.
0:17The catch is that Claude can't actually watch a video.
0:20So it renders every frame in a browser, flips through them like a stack of screenshots, and fixes whatever's broken.
0:27If a label is hanging off the edge of the page, it catches it and redraws it.
0:30Then ffmpeg glues all the frames together and you get this.
0:36I saw this on someone else's TikTok today, dropped it into Claude, and told it to update my skills and make this video.
0:42Tell me what I should make it draw next.
