Cross-Platform 1080p Video Clip Creation in Java

I'm in need of a Java function that can take a movie file and generate video clips.

The function will be provided an array of start and end times for the clips. Clips created should be concatenated and saved as a new file.

The function should have:

In parameters: (File movieFile, List<StartEndTimes> startEndTimes)
Return: File concatenatedFile

The clips should adhere to the following specifications:

- Video Format: MOV or MP4
- Quality: High (1080p)

The Java function should work seamlessly across multiple operating systems:

- Windows
- MacOS
- Linux

Ideal freelancers for this project should have:

- Proficiency in Java, notably audio and video processing
- Experience with cross-platform development
- Strong understanding of video quality parameters and codecs, specifically MOV, MP4
- Ability to ensure high-performance, scalable solutions for video clip generation.
