Operation Manual

Appendix A: Setup options 251
Data code does not work if the tape:
• includes one or more blank (unrecorded) sections
• is unreadable due to tape damage or electronic noise
• was recorded without the camcorder time or date set
• is a copy of another tape
• was shot on an 8mm or Hi8 camcorder, and is now
being played back on a Digital8 camcorder.
Under the final option – “No auto scene detection” – a
new scene is created each time you press the [Space
]
key.
Data rate
The DV format uses a fixed 5:1 compression ratio,
which implies a data transfer rate for real-time capture
of approximately 3.6 megabytes per second (MB/sec).
The transfer rate of your capture drive must be at least
4 MB/sec to allow for any variations across the drive.
Test data rate: Click this button to
test the data rate of your current
capture drive. Studio writes and
reads a file of known length, and
gives you a read-out of the results
in KB/sec (4000 KB/sec equals 4
MB/sec).
If you have attempted to capture DV scenes and your
capture drive can’t accept the DV data rate, a dialog
box will inform you of the problem. You have the
options of choosing another drive or adding one that
meets the data rate requirement.
Folder browser: This button sets the disk directory
(and thus the drive) in which your captures will be
saved, and lets you specify a default file name for
captures. The Test Data Rate button will perform its
test on the drive where this capture directory is located.
