LUT 01 is a custom LUT that I use across all of my videos to have a consistent look. It applies a moody blue-tint to shadows and makes the oranges and reds pop.
Inside you will fine one LUT cube file which can be used in nearly any video editing software. How you apply it is up to you. I recommend color and light correcting your footage before applying the LUT. I usually apply the LUT anywhere between 30-70% intensity.
