If multiple tracks are selected, all selected tracks are adjusted. If you adjust the slider during playback, the behavior varies depending on the selected automation recording mode. For more information, see Automating 5.1 surround projects on page 167.

Adding a motion blur envelope

This feature is available only in the full version of Vegas software.

Motion blur can help you make computer-generated animation look more realistic. For example, if you use track motion or event pan/crop to move a clip across the frame, each frame is displayed clearly when no motion blur is applied. Turning on motion blur adds a motion-dependent blur to each frame to create the appearance of smooth motion in the same way a fast-moving subject is blurred when you take a photograph with a slow shutter speed.

Note: Motion blur significantly increases your rendering time. Adjust the envelope to apply motion blur only where necessary.

1.Right-click the video bus track, choose Insert/Remove Envelope from the shortcut menu, and then choose

from the submenu.

2.Add and adjust envelope points as necessary to set the time interval that will be used for blurring. Increasing the value emphasizes the blur effect. For example, setting the envelope to 0 means no blurring will occur; setting the envelope to 1 second means that each frame will be blurred for one-half second before and after the frame.

3.The motion blur envelope affects all tracks. To bypass motion blur for a track, select the Bypass Motion Blur button () in the track header.

4.To change blur type, choose a setting from the Motion blur type drop-down list on the Video tab in the Project Properties dialog. This setting determines the shape of the blur and the opacity of the frames.

Adding a video supersampling envelope

This feature is available only in the full version of Vegas software.

Video supersampling can improve the appearance of computer-generated animation by calculating intermediate frames between the project’s frame rate, allowing you to create smoother motion blurring or motion from sources such as track motion, event pan/crop, transitions, or keyframable effects.

Note: The effect of video supersampling is less apparent with video that contains fast motion, and supersampling cannot improve the appearance of existing video.

1.Right-click the video bus track, choose Insert/Remove Envelope from the shortcut menu, and then choose

from the submenu.

2.Add and adjust envelope points as necessary to indicate how many frames will be calculated between frames (using the project’s frame rate) to create the blur.

Note: Video supersampling significantly increases your rendering time. For example, when you set the video supersampling envelope to 2, Vegas software renders twice as many frames as it would without supersampling. Adjust the envelope to apply supersampling only where necessary.
