Using video event envelopes
Velocity envelopes are only available in the full version of Vegas software.
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.
Note: Event envelopes only affect an event. Track envelopes affect the entire track. For more information, see Composite level automation (video only) on page 161.
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. For more information, see Using generated media on page 247.
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.
Note: When you have multiple events selected, the opacity of all selected events is adjusted simultaneously.
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 envelope cursor (
).
2.As you drag the cursor, the opacity envelope appears. Both the time in the event and the opacity level are displayed as you drag.
