Adding and applying three source filter tracks

Before you add a three source filter track, add the three video tracks that you want to use as sources for the filter track.

To insert a three source filter:

1. Drag a Three Source Filter Track icon from the QuickTime set  of the Objects palette to the bottom of the track list area of the Timeline Editor.

Note: You must position the filter track at the bottom of the track list in the Timeline Editor to assign it to the top of the layering order (layer 1). (See Setting the layering order of tracks.)

2. Select the three source filter track in the Timeline Editor and display the Three Source Filter Track Inspector.
3. From the Source A menu, choose one of the video tracks that you want to apply the three source filter track to. From the Source B menu, choose the other video track that you want to apply the three source filter track to. From the Luma Matte menu, choose the video track you want to use to control how the source A and B video tracks blend over each other. (To see the effect more clearly, use a high-contrast grayscale video as the Luma Matte.)
4. Select the three source filter sample in the track content area of the Timeline Editor. (If necessary, expand the text track to display the samples.)
5. In the Three Source Filter Sample Inspector, click the Select button.
6. In the Select Effect dialog box, do one of the following:
• Choose a matte from the Matte menu and, if necessary, select parameters for the effect.
• Click Save to save the effect as a .qfx file for use later.
• Click Load to load a previously saved effect.
7. Click OK. GoLive labels the three source filter sample bar in the Timeline Editor with the name of the effect.
8. To add other three source filters that appear at different times in the movie, use the Create Sample tool  to create new three source filter samples. For information on using the Create Sample tool, see Adding and editing samples.
