Dynamic Meta allows you to change the metadata of what is currently playing, to access this press the Update Metadata button from the top of the log screen (speech bubble icon).
You will then see a window open where you can specify the metadata you wish to display. When you click Save, it will immediately be sent to any metadata outputs you have setup within Monitor
You can also trigger this Dynamic Meta update via a command in the log, this command is DYNAMICMETA followed by the text you wish to output.
Finally, you can make Dynamic Meta appear when any PlayoutONE Type is playing. Open Type Manager and enter %%DYNAMICMETA%% in the Meta Override column for the types you wish Dynamic Meta to activate on. Make sure the Billboard checkbox is also ticked for each type otherwise it will not show.
