Content properties
Content properties are sometimes known as Video clip properties and can be accessed be right clicking a content file thumbnail from a layer.
Content properties are unique to a content file. So, by changing the content properties on a piece of content, these properties will apply whenever that clip plays on any layer. The exception to this is if you’ve duplicated the clip instance within the VideoClip library.
