■ NESTED EFFECTS AND COLLAPSING (XPRESS PRO)

When played back, the title doesn’t exactly emulate the path of the Picture In Picture

effect because it was created originally off-center, resulting in an effect that begins off

axis but lands in the right position.

You could continue chasing your tail, creating a new title in the center of the

frame and again emulating the motion of the Picture In Picture effect, but life is short.

And this is a great opportunity to nest.

If you could place the title inside of the Picture In Picture effect, it would track

just fine. Here’s how to do it. Build the Picture In Picture as you normally would, but

before building the title, select the video track with the Picture In Picture effect. Be sure

that your blue position indicator is over the effect.

Now, click the Step In button on the bottom of the Timeline . The button is a

downward-facing arrow, indicating that we are going down into the effect, spelunking

our way through it. The Timeline changes to reflect the Picture In Picture clip only. The

sequence monitor image will also change to reflect the source of the effect in Full

Screen mode.

From here, you can add another video track inside of this nest and create the

title, editing it into the nest as you would any normal sequence. When you’re inside of

a nest, all the normal sequence rules apply. You can build 24 tracks of video in this

nest, just as you can with any sequence. In this example, the source clip of the effect is

in Full Screen mode while you are in the Step In mode, so you can position the title

more correctly when building it. Once you’ve created the title, step out of the nest by

clicking the Step Out icon . The sequence will reappear and your title will be inside

the Picture In Picture. Wherever the Picture In Picture effect goes, your title will follow.

Expansion Nesting

Now we’ll take a look at expansion nesting and an example of when you should choose

this method over step nesting. Let’s start by taking an image that we want to integrate

into a documentary. The image is faded, the color has a blue cast to it, and the shot has

been transferred with the negative reversed. So we’ll need to fix it and we want to pan

across the screen, all the while incorporating a letterbox matte. As we build the nested

effect, we need to pay attention to an audio cue in the narration track, which tells us

when to start the pan of the image from one person across the entire group.

In this scenario, expansion nesting is the best solution. There are two reasons:

We need to hear an audio cue, which we would not normally hear by using the step

method; and we are adding effects to an entire picture, thus there is no need to focus

on any specific image within a group of images.

To begin, I like to add a Submaster effect to the top and then expand the Timeline

to reveal the added effects inside. The reason I choose the Submaster effect is simple: The

Submaster effect has absolutely no characteristics, but it implies that there is something
