Subscribe Feed (RSS)Introducing a Change in Color With a Swipe
April 13th, 2009 by Rob Strobbe | Filed under Tutorials.Adding the Transition
We create the transition between our Black and White footage and our Color footage by overlapping their events. But not in the “usual” way. The usual way to transition between two events is to move one over the other. But that method moves the starting point of the event in time. Try it, and you’ll see that the on screen action actually shifts as we transition between the two events. We don’t want that shift in time — we just the action to play out normally while only the color changes. So, if you moved one of the events to see how it would look, undo that, and we’ll overlap them in a way that won’t disturb the action.
Instead of clicking and dragging the Color event, click and drag the left edge of it. This gives us a larger window into the event’s media, allowing more of it to play out. Since its media is the same as that of the B&W event, the action is identicle. Follow the same step to drag the right edge of the B&W event out further. You may need to select the event first in order to find its right edge (since it’s now overlapping the Color event).
By default, overlapping two events creates a crossfade. Let’s turn this crossfade into something useful. As the B&W event transitions into the Color event, we want the color to move across the screen in conjunction with our blue field, which means we need a Wipe transition. Go to the Transitions tab, select Linear Wipe from the list, then drag and drop the Right-Left, Soft Edge transition onto the crossfade between the B&W and Color events. The default values should be fine.
Figure 5: Using a Linear Wipe
Now we have all the components we need: Two events with the same media but different looks, a wipe transition between them, and a colored swipe to represent whatever force causes the change in appearance. The last thing you will need to do is adjust the overlap so that the blue line and the linear wipe edge are in the same general position at all times. The easiest way to do that would be to move the Swipe event’s Event Pan/Crop keyframes toward the center a little so that the the swipe actually starts a little after the video does and finishes a little before. Then adjust the overlapping edges of the other two events so that the transition starts when the swipe first appears on screen and finishes when the swipe first leaves the screen. For this, I turned on the Sync to Cursor option in the Even Pan / Crop window, moved the keyframes in, and dropped Markers on the main timeline at the same position as the keyframes. Then I dragged the event edges to those markers.

Thank you very much for the effect! i really appreciate it!
I am NEW to Vegas Pro. Can someone please tell me how to create the linear swipe of 2 lines of lyrics at the lower part of the screen (from one color to another), just like a normal karaoke file? Of course the swipe has to occur at the exact times where the words are supposed to be sung. Please tell me the exact procedure. I see the transition Linear Swipe. It seems that I cannot ask it to occur at the exact times I need for a song.
Thanks a lot!
Check the manual / online help for Transition Progress Envelopes. These give you greater control over transitions. You should be able to do exactly what you want by setting points where each word is sung and then moving the progress of the transition at those points so the color changes when you want it to.
