ladaapp/lada ? reverse-engineered prompt

Build me a simple app for restoring pixelated adult videos, with both a desktop style GUI and a command line option. I want to open a video, preview the restored result in real time if the machine is fast enough, or export the cleaned up video to a new file if playback is too slow. Please make it work well on a GPU, but still run on CPU if needed, even if that is slow.

It should feel easy to use, with clear controls for choosing an input file, starting the restore process, watching progress, and saving the result. If you need current install or GPU details, look them up online and follow whatever is standard now. Also make sure the app handles buffering, export settings, and file access cleanly so it works on Linux and can be packaged for other platforms too.
