H
INTS FOR IMPROVING THE CAPTURE PERFORMANCE OF YOUR
HARD DISK
General
During capturing of videos a large amount of data is transferred from the
capture board to the hard disk. You might find that your system cannot keep
up with the required amount of data transfer for the settings you have
chosen.
When capturing, your system might pause, the video might be jerky or jitter
(not smooth), and some of the frames might be dropped (not saved to disk).
Playback quality of such a video is typically unsatisfactory.
To avoid such problems, we herein have described a number of practices to
optimise your system.
Please, bear in mind that each system is reacting different. Something that
improves performance on one system might not be effective on another
system.
Installing hard disks
The Windows operating systems support 32-bit hard disk access. Please
check in Start/Settings/Control Panel/System/Device Manager whether your
hard disk drive or your SCSI controller has been detected by Windows
correctly (no yellow or red warnings in the Device Manager behind the
device groups). If not, the data transfer rate of your hard disk will not suffice
for a satisfying quality when recording and playing back video.
If possible, install a second hard disk for capturing and saving all of your
video clips. For recording and playing back video a SCSI hard disk with
SCSI controllers should be preferred.
You can save temporary files to your system hard disk or another partition.
The Windows operating systems access system files during recording and
playback. If these files are located on the same hard disk as the video clips,
the head has to be repositioned, which leads to one or more dropped frames
(unsmooth playback).
Optimising the hard disk(s)
Because capturing of videos is a very hard-disk intensive procedure,
optimising the files on the hard disk that you will use for capturing is the
most important task in optimising capture performance. In the following you
will find some detailed suggestions for doing this.
Partitioning the hard disk
You can reserve a complete hard disk or a partition of the hard disk
exclusively for digitising video clips.
