tntwise/real-video-enhancer ? reverse-engineered prompt

Build me a desktop app called REAL Video Enhancer that makes videos look smoother and sharper without making it complicated for the user.

I want a simple GUI where I can load a video, choose whether to interpolate frames, upscale resolution, denoise, or try decompressing a heavily compressed video, then start processing and watch progress clearly. It should feel easy to use for normal people, with a preview of the latest rendered frame, scene change detection so fast cuts stay clean, and support for common video output settings. Please make it work on Windows, Linux, and Mac, and keep it able to use different backends depending on what hardware is available, including faster GPU based options when possible. Use the existing look and feel from the screenshots and make sure the app can package cleanly into a desktop executable. If anything important is unclear, look up current docs online before guessing.
