An agent writes a product video as code and renders an MP4 in about four minutes.

LaunchVideo (293 HN points) takes a URL or product description, Opus 5.5 writes the film as code, and a serverless agent renders it deterministically at 1080p with Playwright, Chromium and ffmpeg in microVMs. The page puts it at roughly 90K input and 15K output tokens per video. (launchvideo.io) The full agent, renderer and web app are in diggerhq/shipvideo, created September 24, 88 stars. Very early. "Deterministic render from code the agent wrote" is the part I'd steal for any generative-media pipeline, because it makes the output diffable.
