Changing the interpolation curve
The interpolation curve determines the rate at which Vegas software animates between two keyframe 
settings. You can right-click a keyframe to choose a different shape for the interpolation curve. The shortcut 
menu provides six options: 
Linear, Fast, Slow, Smooth, Sharp, and Hold. Selecting Hold from the shortcut 
menu prevents any animation from being interpolated between two keyframes. The color of the keyframe 
indicates...

Working with keyframes in track view
You can move and modify track keyframes in track view. These keyframes are used in the following three 
track-level effects:
Track effects plug-in (pg. 208)
Track motion (pg. 245)
Mask generator plug-in on a parent compositing track (pg. 226)
Viewing and moving track keyframes
Once you have added keyframes to one of these track-level effects, the track keyframes appear at the bottom 
of the track on the timeline. Click...

Sample uses for keyframe animation
The following section provides several examples of how keyframe animation can be used with features such 
as event panning and cropping, video effects plug-ins, and generated text events.
Animating event panning and cropping
You can combine event panning and cropping tools with keyframe animation to create several special 
effects. For more information, see Cropping video on page 187.

9.Preview the event in the Video Preview window. Adjust the settings in the Event Pan/Crop window as 
you preview the zoom effect.
Using pan-and-scan
Another way to use keyframe animation in the Event Pan/Crop window is panning, or pan-and-scan. Pan-
and-scan is a technique commonly used when film is converted for television. Movie screens and film are 
usually wider (~2.35:1) than television (~1.33:1). When you transfer the film to video, you have four...

8.Preview the event. Add and adjust keyframes as needed to create the desired effect. You can adjust both 
temporal and spatial interpolation for each keyframe:
Temporal interpolation (how the pan occurs over time) is controlled by the keyframe interpolation 
curve type. Experiment with temporal interpolation by right-clicking a keyframe to change the 
interpolation curve type (hold, linear, fast, slow, smooth) and previewing the result. For more...

Animating generated text 
You can add a generated text event to a project by dragging a text generator from the Media Generator 
window. For more information, see Using generated media on page 213. You can then animate the text by adding 
keyframes. 
Not all attributes of generated text media can be animated using keyframes, however. You cannot, for 
example, morph one text message into a different one. Some aspects can be easily and smoothly animated 
using...

Adding track motion
The Track Motion window (accessible by clicking the Track Motion button   on any video track) is used to 
move a video track across a background. This background can be a solid color, another video event, or an 
image. Picture-in-picture effects and scrolling title sequences are two simple cases where this tool is 
important.
The gray area in the center of the window (covered by the blue/gray rectangle) represents the actual screen 
or...

3.Use the buttons at the top of the dialog to allow or prevent movement or scaling. For more information, see 
Changing editing options on page 246.
4.The track motion occurs instantly, and the results are updated in the Video Preview window. 
5.Use the keyframe controller at the bottom of the Track Motion window to establish distinct track motion 
settings throughout the duration of the track. 
During playback, immediate frames are interpolated to create...

Using keyframes in track motion
Keyframes are what create the motion in the track motion feature. You can create, modify, and remove 
keyframes in the keyframe controller in the same way as with any other feature that uses keyframes. For more 
information, see Using keyframe animation on page 237.
The keyframe controller in the Track Motion window has three attributes that can be animated: position, 
shadow, and glow. Each effect can be animated...

Intensity — type a number in the box or click the   button to display a slider you can use to establish 
the transparency of the shadows blurred edge. Decrease the setting for a translucent shadow, or increase 
the setting for a more opaque shadow.

Color — click the down arrow next to the color swatch to display a color picker. Use the sliders or edit 
boxes in the color picker to set the shadow color, or use the eyedropper tool ( ) to sample a color from...
