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

从代码调用 Story concepts

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. 获取 API 密钥

    在控制台创建密钥。它与试用区使用同一余额。

    创建密钥
  2. 发送第一个请求

    与试用区发送的请求相同。把 OPENNAN_KEY 设为你的密钥。

    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. 查询任务

    调用会立即返回任务 ID。查询任务直到完成:

    GEThttps://api.opennan.com/v1/tasks/{id}
    queued
    等待处理
    running
    生成中
    succeeded
    完成:outputs[].url 中是文件
    failed
    失败:不收费

错误及解决方法

  • 401缺少密钥或密钥错误

    用 Authorization: Bearer 请求头发送控制台中的密钥。

  • 402余额不足

    在账单页面充值,然后重新发送同一请求。

  • 400有值不被接受

    查看 error.message,它会指出字段。请使用参数表中的值。

  • 429请求过多

    等几秒再试,每次遇到 429 都等得更久一些。

把 Opennan 添加到你的 AI 应用

安装一次,你的 AI 就能使用 Opennan 的全部工具:视频、图片、聊天、语音、音乐、音效、3D、字幕和配音。选择你的应用,按步骤操作。

MCP 服务器https://api.opennan.com/v1/mcp

适用于 Codex CLI、Codex 应用和 Codex IDE 扩展:它们共用 ~/.codex/config.toml。如果应用或 IDE 读不到 OPENNAN_KEY,请用写入密钥的 config.toml 方式。Codex 每次调用工具前会询问,批准即可继续。

  1. 获取 API 密钥

    在控制台创建密钥。密钥以 sk- 开头,与网站共用同一余额。

    创建密钥
  2. 把密钥保存为 OPENNAN_KEY

    # 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. 安装 Opennan 插件:包含服务器,以及教 AI 选择模型、确认价格、等待结果的技能

    codex plugin marketplace add Opennan/opennan-ai-plugin
    codex plugin add opennan@opennan
  4. 或者只添加服务器

    codex mcp add opennan --url https://api.opennan.com/v1/mcp --bearer-token-env-var OPENNAN_KEY
  5. 或者把这段加到 ~/.codex/config.toml

    [mcp_servers.opennan]
    url = "https://api.opennan.com/v1/mcp"
    http_headers = { Authorization = "Bearer sk-..." }
  6. 确认列表里有 opennan

    codex mcp list
  7. 重启 Codex,然后让它做任何事

    “做一段 5 秒的霓虹街道下雨视频,再配一首歌和一张海报图。”

把 sk-... 换成你自己的密钥并妥善保管:拿到它的人可以花你的余额。没有密钥时应用也能列出工具,但生成内容需要密钥。

在 AI 智能体中使用
