Collapsing Layers into a Submaster Effect
The Collapse feature lets you build your effect at the topmost level. When you are finished, you
collapse the layers automatically into one Submaster effect. This is useful for simplifying a
sequence with complex compositing. After you collapse a complex composite, you can easily
add transition effects to the start and end of the resulting Submaster effect.

You can also use the Collapse feature to simplify the deletion of multilayer segment effects. After
collapsing the effects, you can select the resulting segment and press the Delete key twice to
delete the effect and all the layers.
After your Avid editing application collapses tracks into a Submaster effect, it recognizes a
Submaster effect as a multilayer effect instead of a single-layer effect. This lets you add chroma
keys and other multilayer effects to the nested tracks within a Submaster effect.

You can drag “two-channel” effects (such as chroma keys) onto Submaster effects if the
Submaster segment contains two or more nested tracks. This is useful after performing a
Collapse operation to composite the new Submaster effect over another background.
To collapse layers into a submaster effect:
1. Select all the tracks you want to collapse.
The tracks must be adjacent.
2. Mark an IN point and an OUT point around the area you want to collapse.
3. Click the Collapse button.
Depending on the model of your Avid editing application, the Collapse button might appear
by default in the Timeline top toolbar or in the Tool palette. It is also available from the
Command palette.
Your Avid editing application collapses the tracks into a Submaster effect on a single track.
