System information
1. Right-click a video event, choose Insert/Remove Envelope from the shortcut menu, and then
choose Velocity from the submenu. A velocity envelope is drawn on the event.
2. Drag the envelope up to increase the playback speed of the event, or drag down to decrease its
speed.
Tips:
n Right-click an envelope point and choose a command from the shortcut menu to
choose from velocity presets from 100% reverse-speed playback to 0% playback (a
freeze-frame effect) up to 300% (triple-speed) playback.
n Setting a velocity envelope to a negative value will cause the event to play in reverse.
Video events can only be reversed if there is media to reverse: an event cannot be
reversed past the beginning of a media file. An event that has been reversed will play
backward until it gets to the first frame and will then hold that frame for the duration
of the event.
Adding a transition progress envelope
Normally, a transition progresses from 0 to 100% in a linear fashion over the length of the transition. A
transition progress envelope gives you complete control over a transition: you can hold, reverse, and repeat
individual transitions.
1. Select a transition.
2. From the Insert menu, choose Video Envelopes, and then choose Transition Progress from the
submenu. An envelope is added to your transition.
3. Add points and adjust the fade curves as desired. For more information, see "Adjusting Envelopes"
on page 266.
In the following example, the transition starts, progresses to 50%, reverses direction, and then
finishes.
Changing the fade curve type
1.
Hover over the edge of a fade until the cursor is displayed as a , or hover over an envelope
segment.
2. Right-click to display the Fade Types shortcut menu, and choose a fade type to set the speed of the
fade.
