I worked with Claude Code to create 8 short cartoon clips where two characters talk to each other, each scene in a completely different art style. It uses ElevenLabs for the voices and GPT Image 2 for the art, and Opus 5.5 wrote everything that animates them, including the lip sync, captions, and timing. First up: a pirate showing his robot butler a treasure map, but it's a takeout menu (16-bit pixel art). If you want to try this yourself, here are some instructions I had it put together that you can copy and paste into Claude Code or Codex: --- How to make a short AI dialogue cartoon with Claude Code or Codex: You need: - An ElevenLabs API key with Text to Speech + Voices: Read - An OpenAI key (gpt-image) for the art - Optional: an OpenRouter key so Gemini can listen to and check the audio - ffmpeg, Node, Python, Chrome Save your keys in files (e.g. ~/.config/elevenlabs/api-key), open Claude Code or Codex in an empty folder (in Codex, allow network access), and paste: Make me one ~30 second animated dialogue video (1920x1080 MP4). Characters: [your choice] Situation: [your choice] Art style: [your choice] Write a funny 6-8 line back-and-forth with a punchline. Keys are in ~/.config/*/api-key; never print them. 1. Voices: search the ElevenLabs voice library, audition 3-4 voices per character on a real line, and have Gemini (via OpenRouter) pick the best fit. 2. Speech: eleven_v3 with-timestamps, one request per line, with an acting tag like [exasperated]. Use curl. 3. Audio: trim lines using both the timestamps and the waveform (so nothing is clipped and there's no dead air), fit to 30s, add quiet ambience, and compute a per-frame loudness envelope per character. 4. Art: one 16:9 scene with both characters facing each other, mouths closed. Then one edit per character: "change ONLY their mouth to open mid-word." 5. Mouths: diff each edit against the scene to cut out a feathered mouth overlay. 6. Render: canvas page + Puppeteer + ffmpeg. Show a mouth overlay when that character is loud. Word-synced captions styled to match the art. One fixed shot, both characters always visible, no camera moves, and no black first frame. 7. QA: have Gemini check the audio against the script, fix issues, and check test stills before the full render. Keep all working files in a source/ folder so it can be re-rendered later.
