Movie Creation Guide 1-4
Hard drive space The amount of available hard drive space you need varies from one project to the
next. One important factor is whether you will be capturing and editing in DV or
MPEG. See "Digital Video Formats – DV and MPEG" on page A-6.
The amount of storage you need for your project is the total of:
• All the raw video you will capture — 10 minutes of DV will take up
approximately 2 GB while 10 minutes of MPEG2 video will take up between 300
– 700 MB depending on the level of compression
• 5-10 GB of temporary storage — needed to render the image of a DVD before it
is burned to the DVD media
• storage for other media files, such as audio and pictures
Fast hard drives (7200 RPM) are preferred as they improve the speed of real-time
Preview and video output operations, however hard drives at 5400 RPM also give
good performance. A computer system with a hard drive dedicated to video editing
can make data management easier as well as offer speed improvements when the
drive is on a separate IDE channel from the system drive. Hard drives formatted
with NTFS file systems are preferred over FAT32 since NTFS has no file size limit,
while FAT32 imposes a limit of 4 GB per file.
DVD writer A DVD writer that can handle all the different DVD media types (DVD-R, DVD-RW,
DVD+R and DVD+RW) is preferable. Some consumer DVD players only support
limited formats, so you should ensure that your DVD player supports the same
formats as your DVD writer.
Burning speeds are important as well, as faster writers can greatly speed up the
burning process. As mentioned in the note above for external drives, 1394
connectivity is preferred so there is no bus contention with the Audigy 2 ZS Video
Editor, but USB works well too. See "Selecting the DVD Format and Media Type" on
page 6-1.
External IEEE 1394
hard drives are
preferable over USB
hard drives because
the full USB bandwidth
can be dedicated to
Audigy 2 ZS Video
Editor. USB hard drives
are best connected
directly to the host
system, preferably on
a separate USB hub
from that of Audigy 2
ZS Video Editor, but
can also be connected
to the USB inputs on
Audigy 2 ZS Video
Editor itself.
