Apple Final Cut Pro X 10.1.4 (Mac OS X)

At the heart of Final Cut Pro X is a flexible timeline Magnetic Timeline, a new approach to video editing without the tracks with the ability to add and organize videos as convenient to the author, while the other clips immediately disappear from the screen. The author can use the Clip Connections for pasting clips from other key elements such as titles and sound effects, while maintaining perfect synchronization of all elements regardless of their movement.
