[中文版](./README_CN.md) | **English Version**

A private-deployable, lightweight AI video generation workbench built on **Seedance 2.0**. This Lite open-source version uses local **SQLite3** for data persistence and supports multi-modal reference inputs with zero mandatory cloud dependencies. OSS is optional — reference images work out of the box without any cloud storage.

## ✨ Features

- 🚀 **Model Support**: Full support for Seedance 2.0 multi-modal protocols (image, video, audio references).
- 💾 **Local Storage**: Lightweight SQLite3 database — no complex infrastructure required.
- ☁️ **OSS Optional**: Without OSS, the app automatically switches to local mode — reference images are sent as base64 directly to the API. Zero barrier to getting started.
- 🖼️ **Auto Preview**: Automatically extracts keyframes and generates thumbnails for all generated videos.
- 🔄 **Async Processing**: Built-in background worker polls task status and saves results to local storage.
- ⚡ **Lightweight**: Single-user mode, no login required, ready out of the box.

---

## 🛠️ Installation & Deployment

### 1. Prerequisites
- Python 3.12+
- **FFmpeg** installed and added to your system PATH (required for video metadata and thumbnail extraction).

### 2. Clone the Repository
```bash
git clone https://github.com/your-username/seedance2.0_api_web_Lite.git
cd seedance2.0_api_web_Lite
```

### 3. Create Virtual Environment & Install Dependencies
```bash
python -m venv .venv

# Windows
.venv\Scripts\activate
# macOS / Linux
source .venv/bin/activate

pip install aiosqlite fastapi httpx jinja2 oss2 pillow pydantic python-dotenv python-multipart uvicorn[standard]
```

### 4. Configure .env

Copy `.env.example` to `.env` and fill in the required fields:

```bash
# Required: Volcengine API Key
SEEDANCE20_KEY=Your_Seedance2.0_Key

# Optional: Alibaba Cloud OSS (leave empty to use local mode)
OSS_KEY_ID=
OSS_ACCESSKEY=
OSS_BUCKET_NAME=
```

#### Two Operating Modes

| Mode | Trigger | Reference Image | Reference Video | Reference Audio |
|------|---------|:--------------:|:---------------:|:---------------:|
| **Local mode** (default) | Leave OSS fields empty | ✅ sent as base64 | ❌ | ❌ |
