System information
Stretched audio events will display a percentage in the  lower-right corner of the event to indicate the 
stretched playback rate.  If the media has a known tempo, the effective playback tempo (after stretching)  is 
listed in parentheses after the stretch amount.
Audio and video events that are not synchronized  will be highlighted in the timeline, and the amount of 
offset will be  displayed. Very small offsets that are below the resolution of the timeline  may be displayed as 
0.00. Set the project time format  to samples to see the offset amount.
For more information, see "Repairing Audio/Video Synchronization Offsets" on page 165 and "Time Ruler" 
on page 571.
Grouping Events
After you've arranged your events so they're just where you want them,  you can create groups to lock the 
events together. Once grouped, you may  apply editing tasks to the entire group of events.
When the Cut,  copy, and delete grouped events check box on the Editing  tab of the Preferences 
dialog is selected, cutting,  copying, or deleting  an event will affect all events in the same group. For 
more information, see "Preferences - Editing Tab" on page 601.
Creating a group of events
1.  Select the events you want to group together.
2.  From the Edit menu, choose Group, and choose Create New from the submenu (or press G).
When you add media to the timeline, the events for the audio and video stream are grouped 
automatically.
Adding an event to an existing group
1.  Right-click an event in the existing group, choose Group from the shortcut menu, and choose Select 
All from the submenu to select all of the members of the group.
2.  Press Ctrl and click the event to be added to the group.
3.  Right-click the event, choose Group from the shortcut menu, and choose Create New from the 
submenu.
Events can only be in one group at a time. Adding an event to an existing group essentially clears the 
old group and creates a new one that includes all of the selected events.
Removing an event from a group
Right-click the event you want to remove, choose Group  from the shortcut menu, and choose Remove 
From from the submenu. The event is removed from the group.
