■ NESTED EFFECTS AND COLLAPSING (XPRESS PRO)

You can do this same type of effect on higher tracks for simple snappy transi-

tions. For example, you can create a gate flash (that’s a fancy term for what happens in

telecine when a film is overexposed) effect on filler above your video tracks to transi-

tion from one scene to another. Rather than incorporate it on the same tracks as your

clips, you can place this filler effect on a higher track and save it in an effect bin that

can be used any time.

Now that we’ve shown how you can collapse tracks and inadvertently build a

nest, let’s explore how you can build one manually and why you would want to do it.

Step versus Expanded Nesting (Xpress Pro)

There are two different methods of working with nested effects. The first method is

called step or simple nesting (see Figure 7.19). Step nesting allows you to focus and

isolate a single effect, stepping inside of that effect to its core.

Figure 7.19 (top) The Matte and Fill tracks of a title created with the Title tool; (bottom) How the title

effect appears on the Timeline without nesting

The second method, expansion nesting, expands the Timeline to reveal the inside

of the nest, as well as the rest of your edited sequence (see Figure 7.20). Although they

basically do the same thing, there are advantages for each method.

Step nesting allows you to monitor inside of the effect where you are nesting. So

if you are adding something to the inside of a Picture In Picture effect, the monitor

shows you the video that is inside of the Picture In Picture, not the result of the effect.

This inner view is important for placement and adjustment of parameters of any added

effect.
