The previous version of Adobe premier pro was not stable. The new version is now out. Does it have the plethora button?
This latest version, Adobe Premiere Pro CS6, requires it to be installed on a 64-bit operating system. If your computer is running on a 32-bit version, you may need to upgrade it to 64-bit in order to install this version of Adobe Premiere. Adobe Premiere Pro CS6 works with Windows 7 Service Pack 1 64-bit, and Macintosh OS X 10.6.8 or 10.7 operating systems. If you are installing it on a Mac, make sure that your processor supports 64-bit.
Your video card should also support OpenGL 2.0 and your system must have at least 4 GB of RAM installed on it. Adding more RAM is recommended to make this application work more efficiently.
