Master Timeline
The Master Timeline is a tool for developing a consistent set of
rules and operations for editing effects and synchronizing events
across multiple independent timelines. The Master Timeline is a
single timeline representation of the two-dimensional view of
multiple E-MEM level timelines.
The Master Timeline is composed of the timelines of all currently-
enabled E-MEM levels. Any keyframe that is present on an enabled
E-MEM level is represented as a keyframe on the Master Timeline.
All editing rules are based on the Master Timeline keyframes. All
editing operations are performed on the delegated E-MEM levels.
The Master Timeline is displayed graphically in the Keyframe
Timeline menu as the topmost timeline. The Current Time
Position on the Master Timeline determines the editing rules for
the editing and clipboard operations (Insert Before, Insert After,
Mod, Cut, Copy, Paste), as well as the effect-positioning
operations (Prev, Next, Go To Time, Go To KF) and the Run
Control modifiers (Stop Next KF).
If just one E-MEM level is enabled, the Master Timeline and the
E-MEM timeline are exactly the same. With multiple E-MEM
levels enabled, there will be a keyframe on the master timeline
corresponding to each and every keyframe on each enabled
E-MEM level.
