Understanding the Image Processing Pipeline

Another use of the Primary Out room is to apply corrections to clips after the corrections that have been applied in each of the previous rooms.

As the processed image makes its way from the Primary In to the Secondaries to the Color FX rooms, the corrections in each room are applied to the image that’s handed off from the previous room. Since the Primary Out room is the very last correction room in every grade, it processes the image that’s output from the Color FX room. You can take advantage of this to apply overall corrections to the post-processed image.

In the following example, a series of corrections that affect saturation are made in each of the rooms, but the Primary Out room is used to reduce the saturation of the end result. You can see that the final correction modifies the collective output from every other room.
