CHAPTER 4: ADDING EFFECTS AND TITLES 109
Overlay
Placing titles on a video is the simplest example of an overlay effect. An overlay
could also be a picture-in-picture effect over the anchor's shoulder on the nightly
news, or a lower-third graphic. Overlays are commonly superimposed over a
background video with portions of the overlay being transparent or keyed-out.
Overlay effects can only be performed on clips in the Video1-Video99 tracks,
which are collectively known as the Overlay tracks.
To create an image overlay effect:
1. Place a video clip onto the Video2 track.
2. Place another clip onto the Video1 track and line it up underneath the clip in
the Video2 track.
3. Click Clip: Overlay Options. (This command can
also be selected from the right click pop-up menu.)
The Overlay Options dialog box opens.
4. From the Type list, choose Color Key.
5. On the Overlay clip, click on an area that
represents the color you want to be transparent
with the Eyedropper.
6. Set the Similarity (range of colors to be
transparent) and Transparency (how strongly the
visible image should appear). For more information
on setting key frames, see Using key frame
controls.
7. Click OK to close the dialog box and apply the effect.
If your card supports an external monitor, you can watch this preview directly on
your television by selecting the External monitor button in the Overlay Options
dialog box.
