The Cabin on the Ridge

Leo's journey is told exactly as the lyrics describe — a weary climb rewarded by warmth, a mysterious map, and a hopeful dawn departure. The video ends with the first breathtaking glimpse of the hidden lake, glittering below the mountains. Every visual beat mirrors the song's gentle, wonder-filled tone.

Visual style

Warm amber and honey tones dominate interior scenes; crisp blue-white snow outside creates a cozy contrast. Soft volumetric lighting spills from cabin windows into the dusk. Camera moves are slow and deliberate — wide establishing shots of the mountain, then intimate close-ups inside the cabin. 3D animation with slightly painterly textures, like a storybook illustration come to life.

Story arc

The video opens on a vast snowy mountain at dusk, tiny Leo visible against the immensity of the landscape — immediately establishing scale and wonder. As he reaches the cabin and steps inside, the world shrinks to something warm and safe, full of small discoveries. The old map becomes the emotional turning point — his eyes light up, and we feel the pull of the unknown. Dawn arrives gently, and Leo steps back into the cold world, but now with purpose. The final shot — the hidden lake revealed below the treeline — lands as a quiet, earned miracle.

Key scenes

  1. Leo silhouetted against a violet dusk sky, the glowing cabin window the only warm light on the entire snowy slope — he reaches out and touches the door.
  2. Close-up of Leo's gloved finger tracing the route on the old map pinned to the cabin wall, his breath fogging slightly in the cold air.
  3. Time-lapse of the cabin at night — stars wheel overhead, warm light steady in the window — then dawn blushes pink across the snow.
  4. Leo crests a final ridge at golden hour and stops. Camera slowly pulls back to reveal the hidden lake below, perfectly still, reflecting the morning sky.

Locations

  • snowy_mountain_slope · Steep snow-covered hillside at dusk, purple-blue shadows, sparse pine trees, soft gradient sky fading from orange to violet
  • cabin_exterior_dusk · Small log cabin on a snowy ridge, amber light glowing warmly from two square windows, thin smoke curling from stone chimney
  • cabin_interior · Cozy single-room log cabin, stone fireplace casting warm orange glow, wooden shelves with jars and books, planked floor dusted with snow from the open door
  • cabin_exterior_dawn · Same log cabin at early morning, snow tinted pink-gold by rising sun, long blue shadows stretching across fresh undisturbed snow
  • mountain_ridge_path · Narrow snow trail winding between frosted pine trees, pale morning light filtering through branches, footprints forming behind a small walking figure
  • hidden_lake_reveal · Vast pristine alpine lake in a mountain valley, perfectly still water reflecting gold-pink dawn sky, surrounded by snow-capped peaks, no footprints anywhere

コードから Story concepts を呼び出す

One endpoint and one key, on the same balance as the playground. The request below is the example's own.

POSThttps://api.opennan.com/v1/story/concepts
  1. API キーを取得

    コンソールでキーを作成します。プレイグラウンドと同じ残高を使います。

    キーを作成
  2. 最初のリクエストを送る

    プレイグラウンドが送るのと同じリクエストです。OPENNAN_KEY にキーを設定してください。

    curl https://api.opennan.com/v1/story/concepts \
      -H "Authorization: Bearer $OPENNAN_KEY" \
      -H "Content-Type: application/json" \
      -d '{"script":"Leo, a cheerful young explorer in a green jacket with a big backpack, reaches a snowy log cabin at dusk after a long climb. Warm light glows in the windows. Inside he finds an old map pinned to the wall, showing a hidden lake beyond the mountains. At dawn he sets off again, map in hand.","style":"warm 3D animation","characters":[{"name":"Leo","description":"a cheerful young explorer, green jacket, big backpack, brown hair"}],"direction":"Keep it hopeful and gentle; end on the first view of the hidden lake."}'
    
    # Then poll until "status" is "succeeded" or "failed":
    curl https://api.opennan.com/v1/tasks/<task id> -H "Authorization: Bearer $OPENNAN_KEY"
  3. タスクを確認する

    呼び出すとすぐにタスク ID が返ります。終わるまでタスクを確認します:

    GEThttps://api.opennan.com/v1/tasks/{id}
    queued
    ワーカーの空き待ち
    running
    生成中
    succeeded
    完了: outputs[].url にファイルがあります
    failed
    失敗: 料金はかかりません

エラーと直し方

  • 401キーがない、または間違っている

    コンソールで作ったキーを Authorization: Bearer ヘッダーで送ってください。

  • 402残高不足

    請求ページで残高を追加し、同じ呼び出しをもう一度送ってください。

  • 400受け付けられない値がある

    error.message にフィールド名が出ます。パラメーター表の値を使ってください。

  • 429リクエストが多すぎる

    数秒待ってから再試行し、429 が続くたびに待ち時間を延ばしてください。

AI アプリに Opennan を追加

一度の設定で、AI が Opennan のすべてのツールを使えます:動画、画像、チャット、音声、音楽、効果音、3D、字幕、吹き替え。お使いのアプリを選んで手順に従ってください。

MCP サーバーhttps://api.opennan.com/v1/mcp

Codex CLI、Codex アプリ、Codex の IDE 拡張で使えます(共通の ~/.codex/config.toml)。アプリや IDE が OPENNAN_KEY を読めない場合は、キーを書いた config.toml の方法を使ってください。Codex はツールを呼ぶ前に確認するので、承認して続けます。

  1. API キーを取得

    コンソールでキーを作成します。sk- で始まり、サイトと同じ残高を使います。

    キーを作成
  2. キーを OPENNAN_KEY として保存

    # macOS / Linux (zsh shown; bash: ~/.bashrc)
    echo 'export OPENNAN_KEY="sk-..."' >> ~/.zshrc
    source ~/.zshrc
    
    # Windows (PowerShell), then open a new terminal
    setx OPENNAN_KEY "sk-..."
  3. Opennan プラグインをインストール:サーバーと、モデル選び・価格確認・結果待ちを AI に教えるスキルが入ります

    codex plugin marketplace add Opennan/opennan-ai-plugin
    codex plugin add opennan@opennan
  4. またはサーバーだけを追加

    codex mcp add opennan --url https://api.opennan.com/v1/mcp --bearer-token-env-var OPENNAN_KEY
  5. または ~/.codex/config.toml にこれを追加

    [mcp_servers.opennan]
    url = "https://api.opennan.com/v1/mcp"
    http_headers = { Authorization = "Bearer sk-..." }
  6. opennan が一覧にあるか確認

    codex mcp list
  7. Codex を再起動して、何でも頼んでください

    “ネオン街に降る雨の 5 秒動画と、それに合う曲とポスター画像を作って。”

sk-... をご自身のキーに置き換え、他人に見せないでください。キーを持つ人は残高を使えます。キーがなくてもツール一覧は表示できますが、生成にはキーが必要です。

AI エージェントから使う

エージェントに Opennan の MCP サーバーを追加して、このツールを呼び出します。
