Adobe Creative Suite (CS) is a collection of graphic design, video editing, and web development applications made by Adobe Systems. The collection consists of Adobe's applications (e.g., Photoshop, Acrobat, InDesign), that are based on various technologies (e.g., PostScript, PDF, Flash). The latest version, Adobe Creative Suite 4 (CS4), was announced on September 23, 2008 as the successor to Adobe Creative Suite 3. It was officially released on October 15, 2008. 30-day trials for all products except those in Japanese should be available by mid-November 2008. Japanese-language trials are expected to be available by early December 2008.
Adobe sells Creative Suite applications in six different combinations called "editions"
New in Creative Suite 4
All applications in CS4 feature the same user interface, with a new tabbed interface for working with concurrently running Adobe CS4 programs where multiple applications can be opened inside multiple tabs contained in a single window. It was announced that nVidia CUDA technology is now supported to allow for the accelerated encoding of video.
Adobe CS4 is also developed to perform better under 64-bit and multi-core processors. Adobe Photoshop CS4, Adobe After Effects CS4, Adobe Premiere Pro CS4, and Adobe Soundbooth CS4 will officially support 64-bit. However, Adobe CS4 64-bit will not be available for Mac OS X.  In early testing of 64-bit support in Adobe Photoshop CS4, overall performance gains ranged from 8% to 12%. Those who work with extremely large files may realize noticeably greater gains in performance, in some cases as dramatic as ten times the previous speed. This is because 64-bit applications can address larger amounts of memory and thus result in less file swapping Ã¢ï¿½ï¿½ one of the biggest factors that can affect data processing speed.
