What special file can you use in editing to quickly give your video a specific professional color look, like making it warm or cool, without adjusting every setting yourself?

The special file you can use in editing to quickly give your video a specific professional color look, like making it warm or cool, without adjusting every setting yourself, is called a Look-Up Table, commonly known as a LUT. A LUT is a data file that contains a set of mathematical instructions designed to transform color values from your original video footage into new, predetermined color values. Essentially, for every possible input color, the LUT specifies a precise output color. This transformation is applied uniformly across all pixels in your video, instantly altering aspects such as hue, saturation, and luminance. The main purpose of a creative LUT, often called a 'look LUT,' is to provide a complete color grade or aesthetic style in one step. For example, a 'warm' LUT will shift the overall color balance towards oranges, yellows, and reds, increasing the perceived warmth of the image to evoke a cozy or summery feeling. Conversely, a 'cool' LUT will push colors towards blues and cyans, often desaturating reds, to create a colder, more somber, or dramatic mood. By applying a LUT, video editors can achieve complex, professional color looks that would otherwise require extensive manual adjustments of multiple individual color parameters. This saves considerable time and ensures a consistent visual style throughout an entire video project. While some technical LUTs are used for converting video between different color spaces, such as transforming 'log' footage (a flat, low-contrast recording designed for maximum color grading flexibility) into a standard Rec.709 viewing space, it is the creative LUTs that directly provide the specific artistic 'look' like warm or cool. Common file formats for these files include .cube and .3dl.
