Changing keyframe interpolation curves

To control how the pan is interpolated between keyframes, right-click a keyframe and choose an interpolation curve type from the shortcut menu. Keyframe interpolation curves control how the pan occurs over time. The keyframe color changes according to the interpolation curve you have chosen.

Description

 

Hold

No interpolation takes place. The keyframe's settings are maintained until the next keyframe.

 

 

 

 

Linear

Panning is interpolated in a linear path.

 

 

 

 

Fast

Panning is interpolated in a fast logarithmic path.

 

 

 

 

Slow

Panning is interpolated in a slow logarithmic path.

 

 

 

 

Smooth

Panning is interpolated along a smooth, natural curve.

 

 

 

Adjusting the Smoothness slider

The Smoothness slider controls the perceived motion of sound within the sound field among three or more keyframes. When you drag the Smoothness slider to 0, Vegas software interpolates the changes between keyframes along a linear path. As you increase the smoothness value, the path between keyframes grows more curved and smooth.

1.Double-click a keyframe. The Surround Panner window appears.

2.Drag the Smoothness slider to adjust the smoothness of the spatial interpolation path leading up to this keyframe.

Locking keyframes to events

If you want keyframes to move with an event when it is moved along the timeline, choose Lock Envelopes to Events from the Options menu.
