CURRICULUM GUIDE
Adobe Premiere Pro has design characteristics that scale its performance to match the PC. So if your PC barely
meets these minimum specs, Adobe Premiere Pro will work fine but there may be some sluggishness and a
slight change in the displayed video quality. In this case, you want to make sure there are no unnecessary
programs running in the background. That said, here’s what you can expect:
• You might have to scale Adobe Premiere Pro back to a lower-resolution display to achieve real-time
playback.
• Rendering—converting any files with special effects applied or that don’t match the project audio and
video data rates—will take longer and will consume 100% of your processor’s cycles.
• Audio conforming will take some extra time.
• As you move around on a sequence or work with effects, there will be occasional lags between mouse
clicks and on-screen actions.
My System Recommendations
Adobe Premiere Pro takes advantage of certain technologies. Here’s a few to keep in mind, starting with the top
three most effective performance enhancers:
• RAM. The more RAM you have the better. Adobe Premiere Pro uses 90-120 MB of RAM simply to
function. As you scrub through a video project, Adobe Premiere Pro consumes even more RAM for
media caching, thereby creating smoother playback. By design, Adobe Premiere Pro will use up to
about one-third of your total RAM for caching. On a 1 GB RAM PC, total RAM usage will peak at about
400 MB, or several video frames. If you have 2 GB, that’ll more than double the number of cached
frames, meaning even better playback performance.
• Hyperthreading. Adobe Premiere Pro takes advantage of Intel Pentium 4’s hyperthreading technology.
That is, if Adobe Premiere Pro detects you have a hyperthreading CPU, it will divide its processing into
multiple streams to work faster and more efficiently. The corollary to this is that it also takes advantage
of PCs with multiple processors (both non-hyperthreading and hypterthreading)—such as the
Alienware DV workstation described later in this module). Theoretically (at least until someone makes
such a PC), Adobe Premiere Pro can use up to 16 threads!
Note: Dual CPUs and Hyperthreading in Action
To see graphic evidence that dual CPUs with hyperthreading really are doing their job take a look at
Windows Task Manager (shown in Figure 5.1). Access the Task Manager by right-clicking the task bar (or
pressing Ctrl+Alt+Delete) then clicking the Performance tab. In the case of the Alienware DV workstation,
two Intel P4s with hyperthreading means the PC functions as if it has four CPUs.
