Error Logging Display - Blackmagicdesign ATEM Production Studio 4K Installation And Operation Manual

Error Logging Display

Error Logging records errors in video and audio and is indispensable when reviewing video and
for unattended operation. Errors may be logged for color, brightness or audio threshold levels
as well as loss of video signal, change of video format or audio silence. After setting the
parameters which define when an error should be logged, you can choose to start or stop error
logging, save the log to a file, or clear the log. These functions can be selected from the
buttons in the Error Logging Display or from the Error Logging pulldown menu.
Errors are recorded against timecode and time of day to make them easy to find. If timecode is
not present, errors can be found by reviewing the time of day at which they were recorded. As
computer clocks can drift, it is a good idea to inspect the Date & Time settings on your
computer, and set the clock to synchronize with an Internet time server to ensure accurate time
of day logging.
In Full Screen view, Histogram Display and Error Logging Display share the same area of the
UltraScope interface. Select the LOGGING button, below the Histogram Display, to switch to the
Error Logging Display. Select the HISTOGRAM button, below the Error Logging Display, to
switch back to the Histogram Display. After quitting and reopening the UltraScope application,
the last viewed display will be made visible again, i.e. either Histogram or Error Logging.
In 2-up view, Histogram Display and Error Logging Display can be viewed simultaneously and
so there are no LOGGING or HISTOGRAM buttons.
When viewing the Error Logging Display for the first time, the display will initially be blank other
than for some column headings. Select the START button to commence logging. In Full Screen
view, you can switch back to the Histogram Display and UltraScope will continue to perform
error logging until you choose to stop it.
When error logging is being performed, the STOP button replaces the START button. When the
STOP button has been selected, you can choose to START again and any new errors will be
appended to the existing log. When error logging has been stopped, you can choose to SAVE
the log to a CSV file or alternatively CLEAR the log. The SAVE and CLEAR buttons will not
appear if no errors have been recorded. The CSV file can be analyzed in many applications
including spreadsheet and database software.
By default, error logging is performed using the EBU-R103 standard set down by the European
Broadcasting Union. This standard is popular worldwide and is commonly used as a template
for making new error logging profiles.
