Viz Trio Log Levels
Viz Trio Log Levels can be specified to define the level of detail. For example, log level 0 provides information about critical errors only, while log level 9 will provides information about a wide range of events.
Specify log levels in the General section of Configuration:
Loglevel 0: Only error messages will be logged.
Loglevel 1: Warning messages will be added.
Loglevel 2: Timer messages will be added. These show the amount of time different operations take in the program.
Loglevel 5: Status messages will be added. These show ordinary program events such as "page loaded", "page taken", and so on.
Loglevel 9: All commands sent to the Viz Engine rendering process will be added.
Tip: Messages on log level 0 and 1 (error and warning messages) can also be viewed in the Error Messages Window.
Caution: In many cases it may be beneficial to set a low Media Sequencer Logging level, preferably to 0, since a high level of logging might affect performance when running in a production environment.
