50 Aha & Spot-the-Difference Videos in Half a Day
A one-sentence request for Aha videos featuring Japanese landmarks, cute cats, and cute dogs became more than 50 trials in half a day. The AI agent developed and checked the videos, while a person returned OK or NG decisions and made the final creative judgment.

HOW IT WAS MADE
How the video was made
The user gives one rough request for Aha videos featuring Japanese landmarks, cute cats, and cute dogs. The AI agent develops the subjects, images, gradual changes, videos, and technical checks as trials. A person returns OK or NG decisions with reasons, the agent carries those patterns into the next batch, and the person makes the final judgment about naturalness, difficulty, and interest. The standard workflow reviews a storyboard before video production, but this episode used an approved special rule and produced many short video trials directly without one.
PRODUCTION MATERIALS

I want to use the production method introduced at https://youtu.be/HRmKSoSn3WE as a reference while creating gradual-change Aha and spot-the-difference videos with my own subject matter. First, run the repository prepare-tutorial command in English and validate the matching page at https://manual.nijiunit.com/en/tutorials/HRmKSoSn3WE/. Read the page and every published document, then follow the AI agent guide. Do not reuse the original images, videos, characters, or voices. Use only subject matter and materials that I have the right to use. If I say more instructions are coming, do not begin production until I explicitly say I am finished. First confirm my request, the intended change, what must remain fixed, the answer description, and publication destination. Then show a small set of trial proposals and estimate any paid operation. The standard workflow reviews a storyboard before video production, but if multiple short trials with one shared specification are more appropriate, propose a special no-storyboard rule and obtain my explicit approval. After each trial, record my OK/NG decision and stated reason exactly. Do not invent reasons, and carry the confirmed pattern into the next trial. Passing technical checks does not make a video complete; a person must still judge whether it is natural, challenging, and interesting. Before any YouTube upload, visibility change, homepage implementation, Git commit or push, or paid operation, explain the action and obtain my explicit approval.
