6.In the Video Event FX window, click the Eyedropper button 
( ). The cursor changes to an eyedropper icon.
7.Draw (click and drag) a small rectangular selection area 
around the color(s) to key out. Although you can select the 
color range from just about anywhere, the Video Preview 
window is the best location.
Note: Other effects that can change the color of the event 
should be bypassed when using the Eyedropper tool.
8.Click the Split Screen View button ( ) on the Video 
Preview window to restore the video effects. The Video 
Preview window shows the result of the Chroma Keyer 
plug-in.
When a subject is 
filmed against a solid colored background in a studio, you can key out 
the background color using the Mask Generator or the Chroma Keyer 
plug-in. You can select a wider range of colors using the Chroma 
Keyer plug-in, making it the perfect tool for less-than-perfect blue 
screens.
This procedure selects a small range of colors to use as a key. In the 
example above, the blue sky around the dome is far from uniform and 
it would be difficult to key it out with a traditional blue screen key. 
The color is uniform enough, however, that a range of blues can be 
selected directly from the preview image. Use the controls at the bottom of the dialog box to determine the 
sensitivity of the colors selected. Since the filter selects a range of colors, it is a good idea to try to select a 
relatively small range of similar colors. Drawing a color selection area that spans both blue and red colors 
would make very large sections of an overlay transparent. 
Tip: It is possible to use multiple Chroma Keyer plug-ins on 
a single event, keying out the blues with one and the reds with 
the other, without keying out any colors between blue and 
red.

CHAPTER231
Adding Video 
Transitions and 
Motion
Want something other than a cut or crossfade between video events? Vegas® software provides a wide 
variety of transitions you can add to your project. This chapter also covers track motion and keyframe 
animation, which allows you to automate video effects, media generators, cropping, panning, and more.
Understanding basic transitions
Transitions occur between two video events. Most professional productions, on television or on the big 
screen, use only two types of transitions. The first is a simple cut, where one scene immediately cuts to the 
other without delay or effects. The other is a fade, otherwise known as a crossfade or a dissolve.
Cuts
A cut is actually not a transition. Instead, the last frame from an event is immediately followed by the first 
frame of the next event. This is what happens with two adjacent events on the timeline, either in the same 
track or in different tracks. This can also happen when an event is punched into another (with fade edge 
edits turned off). 
Crossfades
You can fade one event out and fade into the next event by simply overlapping the two. The duration of the 
transition is determined by the amount of overlap. For more information, see Crossfading events on page 75.
Using transition effects
Transition effects are more complex than a simple cut or crossfade. You can replace a crossfade with a 
transition and then customize the transition to meet your needs.

Adding a transition
1.Insert a video event onto the timeline.
2.Insert another event so that it overlaps the first to create an 
automatic crossfade.
3.In the Transitions window, browse for a transition effect. If the 
Transitions window is not visible, choose 
Transitions from the 
View menu. 
4.Drag the effect onto the crossfade between the two events.
Note: The duration of a transition is automatically 
determined by the amount of overlap between the two events. 
As with other events, you can control the precise duration of 
a transition by dragging the edges in and out. You can also 
slide a transition for more precise control. For more 
information, see Sliding a crossfade on page 76. 
Tip: Some transitions also have their own shortcut keys. On 
the numeric keypad, press   to insert a crossfade,   to 
insert a dissolve, and   to insert a linear wipe. Hold   
while pressing   to convert the transition to a cut at the 
cursor position.
Adding a transition to the end of an event
Typically, a transition occurs between two events on a track, but you can also use 
transitions to fade to and from the background, whether that is an underlying 
image, video, or background color. For example, you can drag a Clock Wipe 
transition to the end of a video event and have the wipe go from the video event to 
black.

Adding a transition to all selected events
If you tend to use the same transitions often, you can save yourself some time by adding a transition to all 
selected events at once.
1.Select the events where you want to add the transition.
2.From the View menu, choose Transitions to display the 
Transitions window.
3.Select a transition from the list on the left side of the window. 
The thumbnail images on the right side of the window represent 
each of the existing presets for the selected transition. Hover 
your cursor over a preset to see an animated example.
4.After youve found the setting that you want to use, drag it to 
the position where you want it to occur on the timeline.
5.The Video Event FX dialog is displayed to allow you to edit the 
transitions settings, and a   is displayed in the timeline to 
show you where the transition takes place. You can also click 
this icon to edit the transitions settings.
Dropping on existing cuts, crossfades, or transitions
If you drop the preset on an existing transition, only transitions within the selection will be changed. Cuts 
and crossfades are preserved.
If you drop the preset on an existing crossfade, only crossfades and transitions within the selection will be 
changed. Cuts are preserved.
If you drop the preset on an existing cut, all cuts, crossfades, and transitions within the selection will be 
changed.
Dropping on event edges
If you drop the preset on a transition that is at the beginning or end of an event (but does not span two 
events), only single-event transitions that occur on the same end of the event within the selection will be 
changed.
If you drop the preset on an event fade-in or -out, event fade-ins/outs and single-event transitions that 
occur on the same end of the event within the selection will be changed.
If you drop the preset on an event edge with no fade, all other event edges, event fade-ins/outs, and single-
event transitions that occur on the same end of the event within the selection will be changed.
Note: To change the length of the transition for cuts that are 
converted to transitions, use the Cut-to-overlap conversion 
settings on the Editing tab of the Preferences dialog.
Adding a transition progress envelope
Normally, a transition progresses from 0 to 100% in a linear fashion over the length of the transition. A 
transition progress envelope gives you complete control over a transition: you can hold, reverse, and repeat 
individual transitions. 
1.Right-click a transition.
2.From the shortcut menu, choose Insert/Remove Envelopes, and then choose Transition Progress from the 
submenu. An envelope is added to your transition.

3.Add points and adjust the fade curves as desired. For more information, see Using the Envelope Edit tool on 
page 128.
In the following example, the transition starts, progresses to 50%, reverses direction, and then finishes.
Understanding track layers
If you want, you can view and modify transitions in an A/B roll 
mode. Right-click the track header and choose 
Expand Track 
Layers
 from the shortcut menu to expand the track to reveal 
three layers within the main track. These layers are called the 
A roll, the B roll, and the transition roll.
The concept of an A/B roll is fundamentally different from the multitrack 
philosophy. Every track is in some way mixed (composited) into the final 
output in a multitrack system, but events are not mixed on the A/B roll. 
Instead, either the A roll or the B roll is playing, with the two trading places 
during a transition. You could mix the two for as long as you want with a 
transition, but they do not blend without an intervening transition. 
Transitions move from one roll and into the other. This could be from A to B 
or from B to A. The direction of the transition is automatically set. The small 
arrows on the side of the transition event indicate this direction. 
As the sequence at the right 
shows, the video output can shift from the A to the B and 
back to A many times during a production, but there is only 
one video output from any particular roll at a time. This 
means that the A and B rolls are not composited.
Converting a cut to a transition
The transition between two events that are adjacent to each other on the same track is instantaneous and is 
called a cut. However, if the first event is trimmed back from the end and the second event is trimmed back 
from the beginning (in other words, both have enough media to overlap), you can transform the cut into a 
transition effect using this extra media.
1.Right-click the line between two adjacent events at the cut position.
2.From the shortcut menu, choose Tr a n s i t i o n and then choose the transition that you want to insert (e.g., 
Insert Sony Iris).
You can also drag a transition to the cut from the Transitions window.

The duration of the newly inserted transition event is determined by the Cut-to-overlap conversion time set in 
the 
Editing tab of the Preferences dialog. To access this dialog, choose Preferences from the Options menu.
Note: There must be enough media in the respective events 
to cover the transition (e.g., the end of the first event must 
not be the end of the media file).
Tip: You can also convert cuts between audio events to 
crossfades. Click the cut and press   on the numeric keypad 
to create a crossfade. There must be enough media on either 
side of the cut to create the crossfade.
Converting a crossfade or transition to a cut
1.Click to position the cursor within the transition.
2.Hold   while pressing the   key on your numeric keypad.
The transition will convert to a cut, using the Cut-to-overlap conversion settings on the 
Editing tab of the 
Preferences dialog to determine where the cut occurs.
Previewing a transition
The easiest way to preview a transition is to set the loop region to the duration of the transition and then 
loop the playback. This allows you to adjust the transition while it is playing and make changes in real time.
1.Double-click the transition. This automatically creates a time selection equal to 
the length of the transition.
2.Click the Loop Playback button ( ) to turn loop playback on. The selection area 
bar is dark blue when loop playback is turned on.
3.Click the Play button ( ).
To preview complicated transitions, you may want to build a dynamic RAM preview 
or prerender the effect. For more information, see Building dynamic RAM previews on 
page 256 or Prerendering video on page 255.

Modifying a transition
All of the transitions include several presets that create standard transitions. If a preset doesn’t meet your 
needs, you can customize a transition to suit your taste. 
Tip: You can also animate the parameters of a transition with 
keyframes. For more information, see Using keyframe 
animation on page 237.
1.Click the Transition Properties button 
( ) on the transition or right-click the 
transition and choose 
Tr a n s i t i o n  
Properties 
from the shortcut menu. The 
Video Event FX window appears.
2.Change the parameters. Changes 
update in real time in the Video 
Preview window. For help on the 
different controls in the Video FX 
window, click the 
Plug-In Help button 
( ) to access online help.
Saving custom settings as a preset
After you modify a transition, you can save 
your settings as a preset for use at a later 
time. You can apply presets by choosing 
them from the 
Preset drop-down list.
1.Modify the settings in the window to 
create your desired transition effect. For 
help on the different controls in the 
window, click the 
Plug-In Help button ( ) to access online help.
2.Click the name in the Preset drop-down list. The current text is highlighted.
3.Enter a name for the new preset.
4.Click the Save Preset button ( ).
You can save any additional changes to the custom preset by clicking the 
Save Preset button.

Using keyframe animation
Keyframe animation is a technique that computer artists 
use to quickly make complex animated sequences. 
Instead of drawing every frame of a title scrolling in from 
top to bottom by hand, an animator simply has to set a 
starting and ending position for the animation and let the 
computer interpolate the intermediate frames. The 
animation pictured on the right has three keyframes: a 
starting, middle, and ending keyframe. More complex 
animations use more keyframes. 
While keyframing motion may be the most obvious use 
for keyframe animations, just about any parameter of an 
effect can be animated with keyframes. Keyframe 
animation techniques are used in many areas, including 
transition effects, video effects, event panning and 
cropping, generated media, and track motion. You can 
animate color, brightness, transparency, motion, size, 
perspective, and many other parameters with keyframes.
Understanding the keyframe controller
The keyframe controller appears at the bottom of the Video FX window (used for transitions, effects, and 
generated media), the Track Motion window, and the Event Pan/Crop window.
The cursor position is marked by a flashing line on the controller. This position can also be automatically 
updated on the timeline, with the Video Preview window also updating in real time to reflect changes. Click 
the 
Sync Cursor button ( ) on the keyframe controller to sync the keyframe cursor with the timeline cursor. 
These three frames show the progression
of a title across three keyframes.

Adding keyframes
Every effect has a starting keyframe at the beginning (left side) of the keyframe controller. This sets the 
initial parameters for the effect. In order to animate the effect, you must add another keyframe to the effect 
and change some of the parameters. When you first add a new keyframe, it has the same settings (for the 
transition, effect, pan/crop, etc.) as the first keyframe. You can then modify the settings of the new keyframe 
to create the animation from the first keyframe settings to the second.
1.Click the keyframe controller timeline to move the cursor where you want to add a keyframe. The current 
position is marked by a blinking cursor. 
2.Click the Create Keyframe button ( ). 
3.Modify the settings in the window for the new keyframe as desired. 
Tip: You can also add a new keyframe by positioning the 
cursor in the keyframe controller and changing any 
parameters in the window. A keyframe is added with the new 
settings at the cursor position.
Deleting keyframes
1.Select a keyframe in the keyframe controller.
2.Click the Delete Keyframe button ( ).
Navigating in the keyframe controller
Use the keyframe navigation buttons (First, Previous, Next, and Last) to quickly jump to a keyframe. 
Alternately, press   or   to move to the previous or next keyframe.
Modifying keyframes
After you create your keyframes, you can move them, copy and paste them, and change the interpolation 
curves between them.
Moving keyframes
You can move a keyframe within the keyframe controller by dragging it to a new position. For track-level 
keyframes, you can also move the keyframes in the track view. For more information, see Working with 
keyframes in track view on page 240.
Copying and pasting keyframes
Keyframes on the controller can be copied, pasted, and duplicated. 
1.Right-click a keyframe.
2.From the shortcut menu, choose Copy.
3.Right-click the keyframe controller at the position where you want to paste the keyframe. 
4.From the shortcut menu, choose Paste.
Duplicating keyframes
1.
Right-click and drag a keyframe to a new position.
2.From the shortcut menu, choose Copy. A duplicate keyframe is created at the new position.
You can also duplicate a keyframe by holding the   key while dragging it.
