Final Cut Pro X is a major shift, and you can see this right from the start with its black design. Many programs. like Adobe After Effects and Apple Color, have kept a black design while Final Cut Pro stood out with a light gray background. Now Final Cut Pro X cuts through this with an even darker interface, which may end up playing well when presented next to the images themselves.
The most noticeable addition to Final Cut Pro X is going to be its 64-bit application as well as support for Grand Dispatch, and now will allow you to use a full eight cores of processing. Colorsync will provide full color management for the program and you will see that there is a “Resolution-independent playback system," as they are calling it, that allows a full range of file types up to a full 4k image. This brings Final Cut Pro into a position to act as the all-purpose video editing, from amateur to feature film. Apple is not just tapping into one of the Mac core technologies here, but also going to Core Animation and Open CL.
With Final Cut Pro X, there will be constant rendering of media in the background so that you do not have to actively initiate rendering, which currently takes over the project and stops you from working. Instead, you will be able to have constant render as you are working and let things happen in much more real time. This is going to be of a major advantage for people who need to work on a schedule, and will likely pull users away from Avid.
Avid users will also have to take notice that there is now no waiting during footage ingestion as you will have access to it for editing before it has even fully finished. This process has seen a major uplift as Final Cut Pro X will now be able to detect shot types and provide a non-destructive color balancing as the footage is being captured or imported.
This are only an outline of these Final Cut Pro X features, but will also include a host of audio additions and the ability to do localized adjustments to just parts of images.
