Operation Manual

278 Pinnacle Studio 9
For example:
1 hour of video = 3600 seconds (60 x 60)
3600 seconds x 3.6 MB/s = 12,960 MB
Hence 1 hour of video uses 12.9 GB of storage.
Due to their automatic internal calibration, standard
hard drives regularly interrupt the continuous data
stream in order to recalibrate themselves. During
capture, this is not apparent since images are
temporarily stored in memory. But during playback,
only a limited number of images can be temporarily
stored in this manner.
For smooth playback, a continuous, uninterrupted data
stream is required. If not, the image will “jerk” at
regular intervals, even though all frames are present
and even if the hard drive is very fast.
Preparing your hard drive
Prior to capturing video, you should:
• Close background applications. Before opening your
Studio product, hold down the Ctrl and Alt keys on
the keyboard, then hit Delete. This will open the
Close Program window. Click on the individual
applications listed in the Close Program window and
click the End Task button. Do this for all
applications listed in the Close Program except
Explorer and SysTray. Software utilities are
available for Windows 2000 and XP that can assist
with this procedure.
• Click on Start ¾ Programs ¾ Accessories ¾ System
Tools ¾ ScanDisk
Make sure Thorough is checked, and click Start
(this may take a while).
