An object along with all its nodes can also be stretched or compressed, which affects the contents of video or audio objects, too (pitch).
In the toolbar enable Stretch objects, which can quickly be done by clicking the W key.
Drag the beginning or the end of an object with the mouse to the desired length. All nodes will change their position proportionally. Please note the following:
The playing time of videos changes, too, i.e. they are played back either in slow or in fast motion.
For sound objects
the playing time but not
the pitch will change (requires the Pro License or up). See also Changing playing speed and
pitch.
For sound and video objects, the playing speed can also be altered numerically by changing the speed factor. See Audio Object Properties, Video Object Properties and Picture Sequence Properties.
For playing videos or picture sequences at varying speed, i.e. when they are compressed or expanded, you should definitely use Intermediate Video Data as pitching of original data uses up a lot of computer performance. In combination with Intermediate Video Data the performance demand increases only for a higher data rate, i.e. when the speed is increased.
The ramp band of an object cross-faded with another object on the track, cannot be changed in the cross-fade area. While compressing, nodes in the middle portion may therefore disappear when they get into the cross-fade area.
