User: Generate a typescript react component search input for videos. It must use react-hook-form, use shadcn components only, and have 3 other dropdowns besides the search input itself - sort by, language, and difficulty. SortBy is allow users to sort the videos by length, date published, and difficulty. Clicking on sorting option will reverse it and indicate to the user that there was a change. Language dropdown accepts a list of languages. Difficulty can be either 1,2,3, or 4.

Remember to install the necessary packages:

```bash
npm install react-hook-form @shadcn/ui
```

This improved component uses `Controller` for better integration with `react-hook-form`, handles sorting direction, and provides a cleaner structure.  The styling is minimal, allowing you to customize it further with your own CSS.  Error handling (using `errors` from `react-hook-form`) could be added for a more robust solution.  The search logic (`onSubmit`) is a placeholder and needs to be implemented based on your backend/data source.
