Overview

Each composition embeds one or more time ranges called Work Areas.

By default, a single Work Area is assigned to a composition when it's created, with a duration equal to the length of the composition.

It is visible in the Timeline when the composition is connected to it:

Purpose

Work Areas serve several purposes, to:

  • Define one or more playback areas shorter than the total duration of the composition
  • Truncate the composition and assign it a new duration according to this area
  • Render specific sections of the Timeline, possibly to overwrite certain images in a sequence

By reducing the range of the initial Work Area, you can play a short part of the Timeline in a loop:

Bound by the Composition Duration

If the Work Area hasn't been modified manually by dragging its In and Out points, it will always be equal to the composition duration, even if you shorten or extend its length.

When you move its input or output points, represented by the two outer handles:

  • If you shorten the composition duration, the Work Area Out point will automatically move to match this end.

  • If you extend the composition duration, the Work Area Out point won't move.

  • If you increase the compositon Start Time, the Work Area In point will automatically move to match this Start.

  • If you decrease the compositon Start Time, the Work Area In point won't move.
