+# TVAI - Topaz Video AI Integration Library
+
+A Rust library for integrating with Topaz Video AI to perform video and image enhancement including super-resolution upscaling and frame interpolation.
+
+## Features
+
+- 🎬 **Video Super-Resolution**: Upscale videos using AI models
+- 🎞️ **Frame Interpolation**: Create smooth slow motion effects
+- 🖼️ **Image Upscaling**: Enhance image resolution and quality
+- ⚡ **GPU Acceleration**: CUDA and hardware encoding support
+- 🔧 **Multiple AI Models**: 16 upscaling and 4 interpolation models
+- 📦 **Batch Processing**: Process multiple files efficiently
+- 🎛️ **Flexible Configuration**: Fine-tune processing parameters
+
+## Requirements
+
+- [Topaz Video AI](https://www.topazlabs.com/topaz-video-ai) installed
+- Rust 1.70+ 
+- FFmpeg (included with Topaz Video AI)
+- Optional: CUDA-compatible GPU for acceleration
+
+## Installation
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+tvai = "0.1.0"
+```
+
+## Quick Start
+
+### Video Upscaling
+
+```rust
+use tvai::*;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Quick 2x upscaling
+    quick_upscale_video(
+        std::path::Path::new("input.mp4"),
+        std::path::Path::new("output.mp4"),
+        2.0,
+    ).await?;
+    
+    Ok(())
+}
+```
+
+### Image Upscaling
+
+```rust
+use tvai::*;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Quick 4x image upscaling
+    quick_upscale_image(
+        std::path::Path::new("photo.jpg"),
+        std::path::Path::new("photo_4x.png"),
+        4.0,
+    ).await?;
+    
+    Ok(())
+}
+```
+
+### Advanced Usage
+
+```rust
+use tvai::*;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Detect Topaz installation
+    let topaz_path = detect_topaz_installation()
+        .ok_or("Topaz Video AI not found")?;
+    
+    // Create configuration
+    let config = TvaiConfig::builder()
+        .topaz_path(topaz_path)
+        .use_gpu(true)
+        .build()?;
+    
+    // Create processor
+    let processor = TvaiProcessor::new(config)?;
+    
+    // Custom upscaling parameters
+    let params = VideoUpscaleParams {
+        scale_factor: 2.0,
+        model: UpscaleModel::Iris3,
+        compression: 0.0,
+        blend: 0.1,
+        quality_preset: QualityPreset::HighQuality,
+    };
+    
+    // Process video
+    let result = processor.upscale_video(
+        std::path::Path::new("input.mp4"),
+        std::path::Path::new("output.mp4"),
+        params,
+    ).await?;
+    
+    println!("Processing completed in {:?}", result.processing_time);
+    Ok(())
+}
+```
+
+## AI Models
+
+### Upscaling Models
+
+- **Iris v3** - Best general purpose model
+- **Nyx v3** - Optimized for portraits
+- **Theia Fidelity v4** - Old content restoration
+- **Gaia HQ v5** - Game/CG content
+- **Proteus v4** - Problem footage repair
+- And more...
+
+### Interpolation Models
+
+- **Apollo v8** - High quality interpolation
+- **Chronos v2** - Animation content
+- **Apollo Fast v1** - Fast processing
+- **Chronos Fast v3** - Fast animation
+
+## Presets
+
+The library includes optimized presets for common use cases:
+
+```rust
+// Video presets
+let old_video_params = VideoUpscaleParams::for_old_video();
+let game_params = VideoUpscaleParams::for_game_content();
+let animation_params = VideoUpscaleParams::for_animation();
+let portrait_params = VideoUpscaleParams::for_portrait();
+
+// Image presets
+let photo_params = ImageUpscaleParams::for_photo();
+let artwork_params = ImageUpscaleParams::for_artwork();
+let screenshot_params = ImageUpscaleParams::for_screenshot();
+```
+
+## System Detection
+
+```rust
+// Detect Topaz installation
+let topaz_path = detect_topaz_installation();
+
+// Check GPU support
+let gpu_info = detect_gpu_support();
+
+// Check FFmpeg availability
+let ffmpeg_info = detect_ffmpeg();
+```
+
+## Error Handling
+
+The library uses the `anyhow` crate for error handling:
+
+```rust
+use tvai::*;
+
+match quick_upscale_video(input, output, 2.0).await {
+    Ok(result) => println!("Success: {:?}", result),
+    Err(TvaiError::TopazNotFound(path)) => {
+        eprintln!("Topaz not found at: {}", path);
+    },
+    Err(TvaiError::FfmpegError(msg)) => {
+        eprintln!("FFmpeg error: {}", msg);
+    },
+    Err(e) => eprintln!("Other error: {}", e),
+}
+```
+
+## Development Status
+
+This library is currently in development. The following features are planned:
+
+- [x] Basic project structure
+- [x] FFmpeg management
+- [x] Core processor framework
+- [ ] Video upscaling implementation
+- [ ] Frame interpolation implementation
+- [ ] Image upscaling implementation
+- [ ] Batch processing
+- [ ] Progress callbacks
+- [ ] Comprehensive testing
