Using video event envelopes
Video envelopes allow you to control an event’s opacity or velocity over time. Envelopes appear as lines on an event. With a
velocity envelope, you have the added control of being able to create and edit envelope points.
Using opacity envelopes
Opacity envelopes set the overall opacity and allow you to fade video events in and out. This affects the transparency of the event
in relation to background events on lower tracks. These background events can be other video events or background colors.
Setting a video event’s opacity
When you place the mouse pointer at the top of the event, the pointer changes to a hand cursor ( ) that you can use to lower the
event’s overall opacity.
1. Place the mouse pointer at the top of the event.
2. When you see the envelope cursor ( ), drag the opacity envelope to the desired level. As you drag, the event’s opacity level is
displayed.
You can make fine adjustments by holding Ctrl or clicking the right mouse button while dragging the envelope.
Setting an event’s fade in and out
The event handles allow you to change a video event’s fade in and out. You can also change the type of curve that the event uses to
control the fade in or out.
1. Place the mouse pointer on a handle (upper corners of the event). The pointer changes to the fade offset cursor ( ).
2. Click the corner of the event and drag to create a fade.
You can make fine adjustments by holding Ctrl or clicking the right mouse button while dragging the fade curve.
Note: Event envelopes only affect an event. Track envelopes affect the entire track. For more information, see Composite level
automation (video only) on page 171.
Note: When you have multiple events selected, the opacity of all selected events is adjusted simultaneously.
