Adobe Premiere Pro is a real-time, timeline based video editing software application. It is part of the Adobe Creative Suite, a suite of graphic design, video editing, and web development applications made by Adobe Systems, though it can also be purchased separately. Even when purchased separately, it comes bundled with Adobe Encore and Adobe OnLocation. Premiere Pro supports many video editing cards and plug-ins for accelerated processing, additional file format support, and video/audio effects. Premiere Pro CS4 is the first version to be optimized for 64-bit operating systems, although it is not natively 64-bit.
