Configuring Graticules

The Action Safe, Title Safe and Graphic Safe graticules can be configured to custom sizes.  All sizes are based on a percentage of the video active picture, and are expressed as a value between 0.0 and 1.0.  They are saved in the registry (Windows), 4kscope.plist (macOS) and 4kscope.conf (Linux).  For each (SafeAction, SafeGraphic, SafeTitle), there is a group of settings: left, right, top, bottom.  If the settings and group are deleted, the setting will be recreated with the default/SMPTE/EBU values.  To move the graticule in 10% on all sides, you would set top/bottom/right/left to 0.1.

Configuring Logging Limits

When using the 4KScope/HDRScope logging feature, there are some default limits used to trigger events in the log.  If you wish to change them, they are available in the main config.xml file, which can be edited with the included (Windows/Linux) DDRConfig tool:
