What is a Power Window and how do you use it in color grading?

• A. A Power Window is a mask that isolates a region; create a window, apply corrections to that region, and use tracking to follow motion.
• B. A Power Window is a log transform for color space.
• C. A Power Window is a type of node that blends colors.
• D. A Power Window is a tool to adjust exposure globally.

Answer: (A)

Power Windows are masks that isolate a specific region in a frame so you can adjust only that area. You create a window around the subject or region, apply your color corrections to that region, and then use the tracker to keep the window following the motion across frames. This lets you, for example, brighten or color-grade a person’s skin without affecting the rest of the image, or obscure a region, all while the subject moves. It’s not about a log transform, it isn’t a node that blends colors, and it doesn’t change exposure globally—it's about localized, mask-based adjustments with optional tracking to maintain alignment over time.
