Unite or Split Videos

Create a new video from existing videos by merging them without losing data (i.e taking 2 existing videos and making a new video by attaching them one to another).
Split exiting videos into 2 sub-videos by separating them without losing data (i.e making a new video out of the first part of a video and another new video out of the second part).
Create a sub-video from an existing video by extracting a part of it (i.e recording a part of a video and making a new file out of it).
