What does chrominance measure?

Chrominance specifically measures the color information in a video signal, distinguishing it from luminance, which measures brightness. The concept of chrominance encompasses attributes such as hue (the actual color) and saturation (the intensity or purity of that color). In television production and video processing, chrominance is essential for accurately reproducing colors in images and ensuring that visual content appears vibrant and true to life.

The other choices pertain to different aspects of media production. Sound quality relates to audio fidelity and balance, depth of field describes the range of distance in a shot that appears acceptably sharp, and editing time concerns the duration required to edit footage into a final product. These concepts do not pertain to the measurement of color within a video signal, which is why they are not the correct answer.
