NVIDIARTXVideoTOP

NVIDIARTXVideoTOP is a TouchDesigner component that leverages the Nvidia RTX Video SDK for AI-enhanced video processing. This custom TOP (Texture Operator) enables RTX Video Super Resolution and RTX Video HDR effects to improve sharpness, clarity, and automatically convert SDR video to HDR within TouchDesigner workflows.

Features

• Video Super Resolution (VSR): AI-enhanced video upscaling and artifact reduction
• RTX Video HDR (THDR): AI-enhanced SDR to HDR tone mapping

Requirements

• TouchDesigner 2023.12230 or newer
• NVIDIA RTX GPU
• NVIDIA Graphics Driver r570.58 or newer (avoid Insider Preview drivers)
• CUDA Toolkit 12.8 or newer
• Nvidia RTX Video SDK (set NV_RTX_VIDEO_SDK environment variable to the SDK directory)
• Visual Studio with C++ developer tools
• CMake

Installation

Build from Source

1. Set the NV_RTX_VIDEO_SDK environment variable to the RTX Video SDK directory (the one containing bin, doc, include, lib, samples folders)
2. Make sure CUDA_PATH is set to the Cuda Toolkit 12.8 or newer installation
3. Build Release by running build.bat or:

   ./build.ps1 [Debug|Release|RelWithDebInfo]

   Or manually with CMake:

   mkdir build
   cd ./build
   cmake ..
   cmake --build . --config Release

4. The compiled NVIDIARTXVideoTOP.dll file and dependencies will be copied to test/Plugins

Usage

1. Open test/NVIDIARTXVideoTOP.toe
2. Configure parameters:
   • Mode: Choose between VSR, THDR, or VSR+THDR
   • VSR Quality: Select upscaling quality (Bicubic, Low, Medium, High, Ultra)
   • THDR settings: Adjust Contrast, Saturation, Middle Gray, and Max Luminance as needed
