Reversing a video event

Setting the velocity to a negative value reverses the video, working backwards from the point where the negative value occurs. An event that has been reversed plays backwards until it gets to the first frame and then holds that frame for the duration of the event.

1.Right-click an event, choose Insert/Remove Envelope, and then choose Velocity from the submenu.

2.Trim the beginning of the video event to the place where you want the reversal to begin (e.g., the last frame in the media file that you want to play if it were playing forward).

3.Drag the velocity down to -100% for a normal speed reversal.

This is the original, untrimmed, event. The horses run from left to right.

The event is edge trimmed to the frame where the reversal will begin.

The velocity envelope is added and set to -100%. The thumbnails reflect the change and the horses run backwards. The event can now be repositioned to fit the project.

Removing a velocity envelope

To remove a velocity envelope and all of its settings, right-click the event, choose Insert/Remove Velocity Envelope, and then choose Velocity from the submenu.

Grouping events

You are allowed to group events together within tracks or across separate tracks. Once you create a group, you can move all the events in the group within their tracks as a unit and apply event-specific edits at the same time.

You can still edit properties of individual events within a group without affecting the other events in a group.

Creating a new group

Dragging one event in a group moves all events in the group.

Grouping is useful when you want to preserve timing of events and move events together along the timeline.

1.Select the events you want to group. For more information, see Selecting multiple events on page 96.

2.From the Edit menu, choose Group, and choose Create New from the submenu.
