helmwinchester714/Vidmore-No-Trial — reverse-engineered prompt

I want a Windows desktop app for managing and converting media files. It should let me add video or audio files, choose an output format, adjust simple settings like resolution, bitrate, frame rate, and quality, then convert one file or a whole batch at once. Please include basic editing tools that normal users understand, like trimming clips, cropping the picture, and merging several files into one.

The interface should be clean and easy, with clear buttons, progress status, error messages, and a place to pick the output folder. It should feel stable and safe for regular Windows users, not overly complicated. Please build the project end to end with sensible defaults, sample screens, and enough notes so I can run it locally and understand how to use it. Look up current docs online if you need to, but keep the app focused on reliable video and audio conversion.
