Which process involves adjusting color balance and contrast in video editing?

Color grading is the process that involves adjusting color balance and contrast in video editing. This technique is essential for enhancing the visual aesthetic of a video. During color grading, editors manipulate the color tones, brightness, shadows, and highlights to create a specific mood or atmosphere in the footage. It allows for the correction of any color imbalances that may have occurred during filming, ensuring that the final product is visually cohesive and aligned with the creator's artistic vision.

Other processes listed serve different purposes; for example, chroma keying is primarily used for creating composite images by substituting a color (typically green or blue) with another background. Mixing refers to the blending of various audio tracks together, ensuring that sound levels and balance are appropriate, while editing is a broader term that encompasses the overall process of assembling, cutting, and rearranging video sequences. These processes may involve some aspects of visual adjustments but do not specifically focus on the color balance and contrast adjustments that are key components of color grading.
