System information
1. Hover over the top of a video event.
2.
When you see the envelope cursor ( ), drag the opacity line to the desired level. As you drag the
line, the event’s opacity is displayed as a percentage. As opacity decreases, the event becomes more
transparent.
Tips:
n Hold Ctrl (or hold the right mouse button) while dragging to adjust the envelope in fine
increments.
n When you have multiple events selected, the opacity of all selected events is adjusted
simultaneously.
Fading a video event in or out
You can adjust the opacity at the beginning and end of a video event to fade in or out over a background.
This background can be another video event or a background color.
For more information about compositing, see "Compositing and Masks" on page 385.
1.
Hover over upper-left or upper-right corner of a video event until the cursor is displayed as a .
2. Click the corner of the event and drag to create a fade.
To remove a fade, drag the end of the fade curve back to the edge of the event.
When you have multiple events selected, the fade of all selected events is adjusted
simultaneously.
Adjusting a video event's velocity
Velocity envelopes are used to change the speed of a video event over time. For example, you could use a
velocity envelope to play a clip in slow motion.
Each video event in your project has a specific duration that is not changed by velocity envelopes.
Therefore, if you decrease the speed of a ten-second video event by 50%, only five seconds of video will be
shown. On the other hand, if the speed is increased 200%, the ten seconds of video will play in only five
seconds. The remaining five seconds of the event will be filled either with a freeze of the last frame or with
ten additional seconds of video content from the media file.
