It’s hard to overstate the stars of Adobe CS5 being rewritten in 64 bit and the stars of the show are Adobe After Effects, Premiere Pro and Photoshop.
As you begin to explore you’ll see that on Windows Vista they are installed in a separate Program Files folder, not the (x86). We’ll learn more in coming days but the stars that belong to the 64 bit club are After Effects, Premiere Pro, Photoshop, and Media Encoder. This makes sense. These are the media applications that beg for more memory addressing capability and applications that are confronting the technology of hi definition that make editing and rendering tedious and difficult.
Going from 32 to 64 bit addressing capability in your operating system means an enormous addition to memory you can address but you need to make sure you are running a 64 bit OS. You can’t even install After Effects CS5 if it doesn’t detect a 64 bit OS.
In the Mac World, Leopard or Snow Leopard has you covered.
In Windows, Windows 7 is 64 bit, Windows Vista Home Premium is 64 bit and Vista Service Pack 1 provides 64 bit. However, there’s much more to consider for Windows.
Different release versions of Windows have different memory limitations. There’s a very readable chart available on the Microsoft site at this link.
Windows Memory Chart
The most memory for any 32 bit version is 4 GB. Windows 7 Home Premium can address up to 16 GB. Step up to Windows 7 Professional and the memory limit jumps to 192 Gigabytes. Very significant. That’s 3000 times (3072) the range simply between Window 7 Home Premium and Professional. Either can run After Effects CS5 but to really take advantage of the render and real time editing capability, it’s not a tough decision to make for the nominal expense upgrading to Windows Professional.
Any plugins that you use in After Effects must also have been re-written in 64 bit to work with this new release. Red Giant has released it’s 64 bit version of the complete Trapcode Suite CS5 with Knoll Light Factory 64 bit version scheduled to be released in June.
There is another special advantage to these stars and their 64 bit club membership and that is memory management. The 4 applications that share 64 bit addressing can also dynamically share memory space. This is great for you as you blend these resources, switching from one application to another. By defining memory they can share, Adobe takes care of the sharing part. As you copy from say Premiere Pro or encode a video that you will open next in After Effects to add your effects and other layers, this memory dynamically shifts your memory allocations and needs according to your activity.
