# Venice Video Generate

Full-lifecycle video generation using [Venice.ai](https://venice.ai/). Combines queue, poll, retrieve, and save into a single operation with progress logging. This is the **recommended approach** for video generation.

## Features

- **Single-call generation** -- queue + poll + retrieve + save in one operation
- **Progress logging** every 20 seconds with progress bars and ETAs
- **Text-to-video** and **image-to-video** support
- **Auto-save** to disk with configurable output paths
- **Timeout protection** -- configurable max wait (default: 15 minutes)
- Handles both JSON status responses and binary video data

## Prerequisites

```bash
pip install requests
export VENICE_API_KEY="your_venice_api_key"
```

## Usage

### Basic text-to-video

```bash
python scripts/generate_video.py "A cat playing piano"
```

### With options

```bash
python scripts/generate_video.py "Ocean waves at sunset" \
  --model kling-2.6-pro-text-to-video \
  --duration 10s \
  --resolution 1080p \
  --aspect-ratio 16:9
```

### Image-to-video

```bash
python scripts/generate_video.py "Make this image come alive" \
  --image /path/to/image.png \
