System information
The effect of video supersampling is less apparent with video that contains fast motion, and
supersampling cannot improve the appearance of existing video.
Motion blur without supersampling—multiple exposures are visible
Motion blur with supersampling—multiple exposures appear smoother
1. Right-click the video bus track, choose Insert/Remove Envelope from the shortcut menu, and then
choose Video Supersampling from the submenu.
2. Edit automation settings:
n 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.

Select the Automation Settings button . The Supersampling slider handle is displayed as
a .
The Supersampling slider behaves differently if the track has a supersampling envelope and
when you change the track automation recording mode:
o
When the track automation mode is set to Off, the slider adjusts the supersampling
level of the entire track.
o
When the track has a supersampling envelope and the track automation mode is set
to Read, the slider will follow the envelope during playback but cannot be adjusted.
o
When the track automation mode is set to Touch or Latch, the slider edits the
envelope setting at the cursor position. If the track does not have a supersampling
envelope, an envelope will be added when you adjust the slider.
Video supersampling significantly increases your rendering time. For example, when you set the video
supersampling envelope to 2, twice as many frames are rendered than would be rendered without
supersampling. Adjust the envelope to apply supersampling only where necessary.
