+
+Alibaba Video Generation Model Support for Hypit
+
+## Overview
+
+This package provides integration with Alibaba's video generation models, specifically the **Qwen Video Generation (Qwen VVG)** model. It enables AI-powered video generation with text prompts and optional reference images.
+
+## Features
+
+- **Text-to-Video Generation**: Generate videos from text prompts
+- **Reference-Based Generation**: Use reference images to guide the generation style
+- **Configurable Resolution**: Support for 480p, 720p, and 1080p output
+- **Multiple Aspect Ratios**: Support for 1:1, 16:9, 9:16, 4:3, 3:4 formats
+- **Variable Duration**: Generate videos with 5-10 second duration
+
+## Supported Models
+
+### Alibaba Qwen Video Generation (alibaba-qwen-vvg)
+
+- **Input**: Text prompt (max 200 characters)
+- **Resolution**: 480p, 720p, 1080p
+- **Duration**: 5-10 seconds
+- **Aspect Ratios**: 1:1, 16:9, 9:16, 4:3, 3:4
+- **Optional Reference**: Image for style guidance
+
+## Usage
+
+### Basic Text-to-Video
+
+```markup
+<alibaba:TextVideo
+  id="my-video"
+  model="qwen-vvg"
+  prompt={description}
+  duration="6"
+  resolution="720p"
+  aspect-ratio="16:9"
+/>
+```
+
+### Video Generation with Reference Image
+
+```markup
+<alibaba:ReferenceVideo
+  id="styled-video"
+  model="qwen-vvg"
+  prompt={description}
+  duration="8"
+  resolution="1080p"
+  aspect-ratio="9:16"
+  reference-image={style.image}
+/>
+```
+
+## Configuration
+
+### Prompt
+- Maximum 200 characters
+- Should describe the desired video content clearly
+
+### Duration
+- Range: 5-10 seconds
+- Must be a whole number
+
+### Resolution
+- `480p`: Lower quality, faster generation
+- `720p`: Standard quality (default)
+- `1080p`: High quality, longer generation time
+
+### Aspect Ratio
+- `16:9`: Landscape (default)
+- `9:16`: Portrait/vertical
+- `1:1`: Square
+- `4:3`: Standard
+- `3:4`: Vertical standard
+
+## Architecture
+
+The package follows Hypit's standard model integration pattern:
+
+- **Generation Ports**: Defines input/output structure
+- **Markup Surfaces**: Provides XML/markup interface for video generation
+- **Fragment Builders**: Creates generation fragments with proper request sealing
+- **Surface Decoders**: Converts markup into generation requests
+
+## Dependencies
+
+- `@hypit/artifact`: Artifact type definitions
+- `@hypit/generation`: Generation request/port infrastructure
+- `@hypit/model-kit`: Model module definition utilities
+- `@hypit/markup`: Markup surface definitions
+- `@hypit/elaborator`: Fragment building and activation context
+- `@hypit/text`: Text type definitions
+- `@hypit/protocol`: Core protocol definitions
