Could you build this?
Partial The marketing site and UI are simple, but executing client-side 4K neural video upscaling entirely in the browser demands advanced WebGPU, ONNX Runtime Web, and WebAssembly model optimization.
What it would actually take: Architecture requires ONNX Runtime Web or Transformers.js running over WebGPU, combined with WebCodecs API and FFmpeg.wasm for client-side video decoding and frame-by-frame processing. The hard part is managing GPU memory constraints, preventing browser tab crashes during high-resolution 4K rendering, and quantizing ESRGAN or Real-ESRGAN models to run performantly on consumer hardware. This requires specialized knowledge of computer vision model quantization and WebGPU compute shaders.
