Launch video for an AI inference startup
A 26-second keynote-style launch video for an inference startup, from one vague sentence that names no company or product. Claude Code built it as a web animation and recorded it with Playwright and FFmpeg; the creator puts it at 1 minute and about $2.
“Claude coded this website animation and took a video of it!”

- Playwright and FFmpeg available to the agent
How it was made
No video-generation model and no extra libraries were used: "Just jacascript, playwright and ffmpeg." The audio was handled automatically; the creator says they usually give Claude Code an audio-generation key when they want a voice.

A clean, keynote-style launch film for a made-up inference company called muda: white pages with crisp type, one violet title card, a GPU utilization grid, a token stream, and a dictionary entry for the name.
- Color
- White and very light gray with navy-black text and a single blue-violet accent, pastel pill colors in the token stream, and a soft pastel gradient band behind the logo.
- Type
- A heavy grotesque sans for headlines (WASTE., Most of inference is waiting., We removed the waste.), a light serif for muda in the dictionary card, small monospace labels and counters in the corners, and faint kanji (無駄) as texture.
- Framing
- A film-style frame on every shot: MUDA / FILM 01 and a running timestamp at the top, a chapter label (01 — THE BAIT, 07 — THE MARK) and 1920×1080 · 30 FPS · 120 BPM at the bottom. Content sits left-aligned or centered with wide margins.
- Structure
- A chat prompt stuck on Thinking..., WASTE. on violet, a GPU cluster grid at 40% utilization, a token stream at 882 tok/s, the dictionary card for muda (無駄, waste), We removed the waste., the muda. logo with Inference, minus the waiting., then a receipt: this film 26.000 s, your answer 0.038 s.
