Timeline

The timeline object manages all of the objects in a video editing project. To create this object, call CoCreateInstance. The class identifier is CLSID_AMTimeline.

To read Windows Media™ files, the application must provide a software certificate, also called a key. Register the application as a key provider through the timeline's IObjectWithSite interface. For more information, see Unlocking the Windows Media Format SDK.

The timeline object exposes the following interfaces:

• IAMSetErrorLog
• IAMTimeline
• IObjectWithSite
• IPersistStream
