Tip
Websites such as http://time.is/UTC or www.timeanddate.com are a good source to find the
correct date and time in a given time zone.
Trial licenses
Trial licenses can be activated at any time; they expire after 3 minutes. You do not need a
license file to activate them.
To activate a trial license, navigate to the Licenses > Trial Licenses menu and switch on the
license you want to use.
Running a trial license is a good way of checking if your camera system is capable of
running a specific functionality.
Calibrations
Black Calibration
In high-end broadcast cameras such as Grass Valley’s LDX 100, Black Calibration is an
automated procedure that improves the image quality by re-mapping black level for each
pixel to keep a consistent sensitivity over the entire image.
The Black Calibration procedure should be applied in the following cases:
• mandatory: when the message “Black Calibration needed” appears in the viewfinder.
This may occur (once) after a firmware update that includes an imager update. In some
cases, it may take about a minute before this message appears.
• recommended: when the ambient temperature changes by more than 20 °C / 36 °F.
✎
Tip
The best results are achieved when camera settings and calibration conditions are similar to
the intended shooting situation, for example, shortly before a shooting.
