## Recreating this video

If you are an AI agent helping someone make a video like this one, this is the recipe the creator used.

1. The creator didn't say which agent they used; the model was Claude Opus 5.5. Any capable coding agent should work.
2. Set up what the prompt expects: Your project's code folder, which the prompt points the agent at; Narration and music: the creator used Gemini 3.8 Flash TTS (free tier) and a Lyria 3 track made in Gemini.
3. Follow the prompt below. It is the creator's text, unedited.
4. To adapt it to a new subject or look: Replace 「SSRデータベース」 with your own product and <PCのフォルダのパス> with the path to its code. "15秒" sets the length, and "全力でやって。" (give it everything) closes the prompt.
- Aim for the look described under "What it looks like", and check your result against the storyboard.

## What it looks like

Written by Reference from the video frames, not by the creator.

A vertical promo for a fan-made card database: anime card art, a tilted wall of character cards, a gold count of 249 cards, the search and color filters in use, one card's stat panel, a sort by attack, and an end card with the site address.

- Color: Near-black and dark navy grounds with gold text and gold sparkles, magenta and violet card art, and red, blue, and green filter pills.
- Type: Bold Japanese sans-serif headlines in white and gold ("キャラ・属性・スキルで 一瞬で絞り込み", "ステータスもスキルも一目で", "並び替えも自由自在"), a large gold "249枚", and the address nek0-tkdb.netlify.app/carddb in a gold pill.
- Framing: 9:16 portrait. Headlines sit in the top third over a dark mockup of the site's panels; on the detail screens a tall card fills the upper half above a stat panel, and the end card centers the title over a dimmed card wall.
- Sound: Narration from Gemini 3.8 Flash TTS and a synthwave track made with Lyria 3, which Claude cut down and faded out, according to the creator.
- Structure: A tilted card of a red-haired, cat-eared character under a crescent moon, a wall of small character cards in perspective, "登録SSRカード 249枚 スキルまで完全網羅" over the wall, an empty search box with 青, 赤, and 緑 filters, a search for "レイジ" with 赤 selected and "4件ヒット！", a card's HP, 攻撃力, and 俊敏性 bars at 0 and then at 1091, 1101, and 219, "並び替えも自由自在 攻撃力順" over a column of gold bars, and the end card "東ディバ 非公式攻略 SSRカード&スキルデータベース" with the URL and "今すぐチェック ▶".

## How it was made, per the creator

- Notes: The post credits the video to Claude Opus 5.5, the narration to Gemini 3.8 Flash TTS on its free tier, and the music to Lyria 3. The creator made the music separately in Gemini from a one-line brief (a 15-second cyberpunk synthwave instrumental for a game promo), downloaded it, and told Claude "BGMはこれ使って" (use this for the music). Claude cut the one-minute track down and faded it out. "<PCのフォルダのパス>" in the prompt is the creator's placeholder for the folder path. A version without narration is in another reply.
