Auto-Nesting

Although nesting is a great feature of Avid Xpress Pro, you'll occasionally build a sequence where nesting needs to be added to several clips. Avid Xpress Pro is one step ahead of you on this one. It has a feature called auto-nesting.

When you apply an effect to cliplet's use a color effect as an examplethe effect "lays" over the clip. If you wanted to place a second effect over the clip, let's say a mask, this effect would replace the color effect. So let's say you wanted an entire series of clips to have two effects on them such as the two in this example, a color effect and a mask. First add the color effect to the clips in the Timeline. This example has five clips, as shown in Figure 11.19.

Figure 11.19. There are five clips in this Timeline, with a color effect added to each.

If I were to add a mask to any of these clips, it would replace the color effect. To avoid canceling an effect, use the auto-nest feature.

1. Shift-click each clip in the Timeline using a Segment Mode button or draw a lasso entirely around the clips while inside the Effect mode.

2. Open the Effect Palette and find the effect you want to place on the clips. This example uses a mask effect.

3. Instead of dragging and dropping the effect on a clip in the Timeline, hold down the Option key (Macintosh) or the Alt key (Windows) and double-click the effect. Because the clips were already selected, the effect is placed over all the clips.

4. The Timeline will only display one large clip with the new effect placed on top. The original clips are auto-nested inside the effect (see Figure 11.20).

   Figure 11.20. When you auto-nest an effect on top of a series of clips, only the top effect is displayed.

   

   
   

Auto-nesting provides a quick-and-easy method for applying two effects to a series of clips. If you need to change a clip, you have to nest into the mask effect to see the original clips that had the color effects placed on them.
