Error Logging Display
'Error logging' records errors in video and audio and is indispensable for unattended operation,
such as during long conversions. 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 the timecode
is not present, errors can be found by reviewing the time of day at which they were recorded.
In the 'full screen' view, 'histogram' and 'error logging displays' share the same area of the
UltraScope interface. Select the 'logging' button, below the 'histogram display', to switch to
'error logging display'. Select the 'histogram' button to switch back to the 'histogram display'.
In '2-up' view, 'histogram' and 'error logging displays' can be viewed on two panels simultaneously.
From the Histogram Display, select the Logging
button to switch to the Error Logging Display.
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 stops, you can choose to save the log to a
CSV file or alternatively clear the log. If no errors have been recorded, the 'save' and 'clear'
buttons will not appear. 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 by the European
Broadcasting Union. This standard is popular worldwide and is commonly used as a template
for making new error logging profiles.
