Placeholders [VCon UG]
As a principle, Placeholders are considered as VidiCore Collections holding inheritable metadata.
There are different ways to deal with placeholders in VidiControl.
Create a new Recording based on a placeholder from VidiControl UI
On the timeline view, the Lane Header Context Menu, the Lane Context Menu and the Actions Menu offer possibilities to create a new recording based on a placeholder. This will open the collection search dialog:
