Could you build this?
Partial Creating the desktop frontend and packaging FFmpeg pipelines is straightforward, but setting up a reliable multi-backend offline neural inference engine (CUDA/Vulkan/DirectML fallbacks) with custom super-resolution models requires non-trivial native ML runtime engineering.
What it would actually take: Built with C++/C# desktop framework (WPF/WinUI/Electron) wrapping ONNX Runtime or libtorch with DirectML, CUDA, and Vulkan backends, piped to FFmpeg for frame extraction and re-encoding. The hard part is managing GPU memory pressure, thread synchronization across thousands of frames, and robust fallback handling across heterogeneous consumer GPUs.
