Fix parameter type conversion issue and improve script functionality

Resolved the issue with SwitchParameter type conversion by updating the script to explicitly handle default parameter values.
Enhanced error handling for parameter overrides, ensuring compatibility with optional parameters like -TimeLimit and -VideoLimit.
Improved documentation:
- Clarified parameter behaviour, including default values and interactions.
- Added detailed examples showcasing both video processing and cropping-only modes.
- Updated notes to reflect the workflow changes and error-handling mechanisms.
Improved user feedback by refining log messages and ensuring script consistency during interruptions or errors.

These changes address functional issues and improve the overall usability, clarity, and reliability of the script.
