Submaster Editing
The Submaster effect is a single-track segment effect, available in the Image category of the
Effect Palette. You can apply the Submaster effect to a track above layered or nested effects and
then render only the Submaster. Your Avid editing application renders the composite result of all
tracks into the top track. Rendering a Submaster effect saves the new Submaster clip to the drive
as a single media file. However, your Avid editing application leaves each element that makes up
the composite untouched, so you can still manipulate any element.
The Submaster effect is useful when you want to play back bandwidth-limited sequences, such
as sequences composed of several seconds of single-frame clips. It is much faster to use the
Submaster effect than to use methods such as applying a graphic, or using a Picture-in-Picture,
Mask, or Resize effect. Normally, Submaster effects render at about the same rate as motion
effects.
The Submaster effect maintains links to the original media files, so you should not delete the
original media files. If you want to combine tracks to create a sequence that is independent from
the original media files, perform a video mixdown. For more information, see “Performing a
Video Mixdown” on page 281.
The Submaster effect does not render each track separately, so you cannot play each track
individually, and the blue dot remains in the effect icon. If you delete or modify a track below a
Submaster effect, the Submaster effect becomes unrendered.

You can nest up to 24 tracks inside a Submaster effect depending on the model of your Avid
editing application.
An edit decision list (EDL) for a sequence that contains a Submaster effect represents the
contents of the Submaster effect as a single cut. To work around this, you can create a new
sequence with the contents of the Submaster effect and generate a separate EDL for that
sequence.
