View a node in context with another node to compare intermediate results throughout the process tree. By working with context points, you can modify nodes in the process tree and immediately view the impact those changes have on the nodes further along in the process tree. You can set two context points in a process tree.
You can set a context on a node or on any of its output tabs. You can also set a context on any node output in a group as well as on any output of an Action multiple output node.
A dotted green line appears around the node, and (C1) appears next to the node name in the schematic.

In this way, you are colour correcting “in context” of the intermediate result. Furthermore, as you move to different frames in the tool, Context 1 also displays the result at the same frame. For instance, if you are at frame 15 in the Colour Corrector, Context 1 (Action) is also at frame 15. (Exceptions to this occur when using time-based nodes such as Pulldown, Interlace, and DeInterlace.)
