What they did
Developer liyupi wrote down his whole promo-video process as rules a coding agent can follow. He added a video-making template and helper scripts. You give Claude Code, Cursor or Codex a product name or web address. The agent researches it, asks two rounds of questions, sketches 3-4 looks, takes 4K screenshots, cuts to the beat and adds a generated voice. You confirm details, pick a look, log in where needed, and approve music and voices.
How it went
The author shows five promo videos made with the tool, each in a different style. Each was revised over real rounds of feedback. The lessons went back into the rules as 60+ recorded pitfalls. Final 4K videos take 4 to 18 minutes to produce.
Worth knowing
The video tool, Remotion, is free only for individuals and companies of up to 3 people; bigger teams need a paid license. The voice service ElevenLabs can't be used for business on its free plan, and making music to fit the video needs a paid plan.
Try it yourself with Claude Code
Make a promo video for [product name or URL]. First research the product and list its key selling points with sources. Then ask me about aspect ratio, length, audience, style, opening and music, giving a recommended option for each. Propose 3-4 distinct style directions with one sample frame each, and wait for my choice. Capture real 4K screenshots of the product and ask me to log in if a page needs it. Cut the edit to the music's beats. If you add narration, transcribe it back and check that every brand name and URL is read correctly. Let me listen to the music and voice before you finalize, then render and review each scene before delivering.Swap the highlighted [parts] for your own details.
