Apple Final Cut Pro

At the heart of Final Cut Pro X is the Magnetic Timeline, a trackless approach to editing your footage that lets you add and arrange clips wherever you want them, while other clips instantly slide out of the way.

You can use Clip Connections to link primary story clips to other elements like titles and sound effects, so they stay in perfect sync when you move them. You can even combine related story elements into a Compound Clip that can be edited as a single clip. The groundbreaking new Auditions feature lets you swap between a collection of clips to instantly compare alternate takes.
