What is measured by luminance in video production?

Luminance in video production specifically refers to the brightness of light emitted or reflected from a surface. It is a critical concept in image quality, as it quantifies the intensity of light that can affect how well an image can be perceived by the human eye. In video production, managing luminance is vital for achieving proper exposure, contrast, and visual clarity in footage.

While color quality encompasses factors like hue and saturation, it is not captured by luminance, which focuses solely on brightness levels. Sound intensity and frame rate are unrelated to luminance; sound intensity pertains to audio levels, and frame rate refers to the number of frames displayed per second in video playback. Therefore, when discussing luminance, the correct association is with brightness, making this answer precise in the context of video production.
