Color grading is an extremely important step in video post-production.
By adjusting the colors and contrast of your footage, you can make the video look far more
cinematic and establish a distinct visual style.
During the color grading process, many editors use LUTs to quickly adjust the colors of a
shot.
So, what is a LUT? And how should it be used?
Below are the basic concepts and usage methods for LUTs.
1️⃣ What is a LUT?
LUT stands for Lookup Table, and it is a tool used to map and adjust image colors.
Simply put, a LUT can be understood as:
- A set of pre-configured color adjustments
- A way to quickly alter a video's color tone
- A tool to give footage a specific look or style
For example:
- Cinematic color tones
- Warm, vintage styles
- Cool, modern styles
By applying a LUT, you can instantly give your video footage entirely different visual effects.
2️⃣ Common Uses for LUTs
In video post-production, LUTs are commonly used for the following scenarios:
- Adjusting the overall color palette of a video
- Establishing a specific video aesthetic
- Quickly completing foundational color correction
- Simulating classic film looks
Therefore, LUTs are extremely widespread in video editing and post-production.
3️⃣ How to Use a LUT?
Using a LUT in editing software is typically very simple.
The basic workflow is usually:
- Import your video footage
- Open the color grading tools
- Apply the LUT file
- Make detailed sub-adjustments
Common editing software that supports LUTs includes:
- Adobe Premiere Pro
- DaVinci Resolve
- Final Cut Pro
Through these tools, you can quickly apply a LUT to your video footage.
4️⃣ What to Keep in Mind When Using LUTs
While LUTs can rapidly adjust an image, there are still a few key points to bear in mind when using them:
- Different footage requires different LUTs
- You still need to make micro-adjustments after applying a LUT
- Avoid over-grading your footage
Appropriate adjustments ensure the footage still looks natural.
5️⃣ LUT Usage Example (Adobe Premiere Pro)
Here is a simple demonstration of the basic steps to apply a LUT in Adobe Premiere Pro.
First, import your video footage into Premiere Pro and drag it onto the timeline.
Then, follow these steps:
- Click and select the video clip on the timeline
- Open the Lumetri Color panel
- Find Input LUT under Basic Correction
- Click Browse
- Select your downloaded .cube LUT file
Once applied, the color tone of the video will change instantly.
If further tweaks are needed, you can fine-tune them in Lumetri Color:
- Exposure
- Contrast
- Saturation
- Temperature
Through these tweaks, you can make the LUT effect feel much more natural.
🎨 LUTs Can Elevate Video Quality
By color grading with LUTs, your video footage can:
- Have highly consistent colors
- Feature a distinct and clear style
- Experience an overall increase in quality
As such, LUTs are incredibly practical tools in video post-production.
