How To Enhance Color Grading With LUTs In DaVinci Resolve

Author:

Introduction

Color grading is an essential part of post-production, helping to create the desired mood and visual aesthetic for your footage. It transforms raw footage into a polished, cinematic look that communicates the intended tone and emotion. One of the most powerful tools in the color grading process is the LUT (Look-Up Table). A LUT is a mathematical formula that alters the color and tone of your footage, helping you achieve consistent color adjustments with ease.

In DaVinci Resolve, LUTs are integrated into the color grading workflow, enabling you to enhance the appearance of your footage quickly and professionally. Whether you’re working on a film, a commercial, or even social media content, LUTs can drastically speed up your color grading process while providing high-quality results.

In this guide, we’ll go through the process of using LUTs in DaVinci Resolve, explaining how to apply them, adjust them for the perfect look, and understand how they interact with different footage types. We’ll also touch on advanced techniques to help you integrate LUTs into your grading workflow and achieve the best results.

What Are LUTs (Look-Up Tables)?

A Look-Up Table (LUT) is essentially a mathematical formula used to map one color space to another. When applied to video footage, a LUT adjusts the color values, brightness, and contrast, essentially transforming the look of the image. LUTs are widely used in video editing and color grading to achieve specific color effects, recreate a film stock look, or standardize footage across different cameras and lighting conditions.

There are two types of LUTs commonly used in video production:

  • 1D LUTs: These LUTs only adjust one color component at a time (e.g., red, green, or blue). They are simpler and typically adjust overall brightness or contrast.
  • 3D LUTs: More complex than 1D LUTs, 3D LUTs apply transformations across three color components simultaneously, affecting the entire color space of the footage. They are more commonly used in advanced color grading because of their ability to provide detailed and nuanced color shifts.

In DaVinci Resolve, LUTs can be used to both correct the footage and creatively stylize it.

Step 1: Understanding the Different Types of LUTs in DaVinci Resolve

DaVinci Resolve offers a wide range of LUTs, each with a different purpose and effect on your footage. Understanding the types of LUTs available will allow you to choose the right one for your specific project needs.

1. Technical LUTs

Technical LUTs are primarily used for color correction. They help in transforming the footage from one color space to another, such as converting Log footage (which has a flat, desaturated look) into Rec. 709 (a standard color space for HD television and digital screens). Technical LUTs are commonly used when working with different camera profiles to ensure the colors are standardized and the image looks more natural.

2. Creative LUTs

Creative LUTs are designed to apply a specific style to your footage. These LUTs can give your footage a certain “look,” such as a vintage film effect, a moody color grade, or a high-contrast cinematic appearance. They are often used after the technical grading process to fine-tune the aesthetic of the footage.

3. Film Emulation LUTs

Film emulation LUTs are designed to simulate the look of different types of film stocks. These LUTs can mimic the color, grain, and contrast of specific brands and types of film, such as Kodak, Fuji, or Polaroid. Film emulation LUTs are popular among filmmakers and videographers who want to recreate the nostalgic or timeless feel of traditional film.

4. Custom LUTs

While DaVinci Resolve comes with an extensive library of built-in LUTs, you can also create custom LUTs based on your color grading work. These custom LUTs allow you to save and apply your color grading adjustments across multiple clips or projects, streamlining your workflow.

Step 2: Applying a LUT to Your Footage in DaVinci Resolve

Now that you have an understanding of what LUTs are and the different types available, let’s dive into how to apply them to your footage in DaVinci Resolve.

1. Importing Your Footage

Begin by importing the footage you want to color grade into DaVinci Resolve. Make sure you’ve already edited your footage in the timeline, as LUTs are typically applied during the post-production phase. Once your clip is in the timeline, you’re ready to start the color grading process.

2. Navigating to the Color Tab

To apply a LUT in DaVinci Resolve, you need to switch to the Color Tab. This is where all the color grading tools are located. Once in the Color Tab, you’ll see the color grading panel, which includes options for adjusting lift, gamma, gain, and various curves.

3. Opening the LUTs Panel

On the left side of the Color tab, you’ll find the LUTs Panel. If it’s not already visible, click on the LUTs icon (a small grid-like icon) to open the panel. Inside the LUTs panel, you’ll see several categories of LUTs, such as Creative, Technical, and Film Looks.

4. Applying the LUT

To apply a LUT, simply navigate through the categories in the LUT panel and drag the desired LUT onto your clip in the timeline. DaVinci Resolve will instantly apply the color transformation, and you’ll see the change in the viewer window. You can apply a LUT directly on the node in the Nodes Panel, allowing you to build more advanced grading setups using multiple nodes.

Step 3: Adjusting the LUT for Optimal Results

While applying a LUT can dramatically change the look of your footage, it’s often necessary to adjust the effect to ensure it suits the specific scene or desired outcome. Here’s how to tweak a LUT for the best possible look:

1. Adjusting Intensity

Once the LUT is applied, you might find that the effect is too strong or not strong enough. DaVinci Resolve allows you to adjust the intensity of the LUT to achieve a more subtle or enhanced look.

  • Select the LUT in the LUTs panel.
  • In the Inspector Panel, adjust the Mix slider to control the intensity of the LUT. Lowering the mix will reduce the effect, while increasing it will intensify the colors.

2. Fine-Tuning with Color Wheels

You can further refine the LUT’s impact by adjusting the color wheels for Lift (shadows), Gamma (midtones), and Gain (highlights). This allows you to make subtle color corrections that complement the LUT. For instance, if the LUT makes the shadows too blue, you can warm them up by shifting the Lift wheel toward yellow.

3. Using Curves for Precision

DaVinci Resolve offers a robust set of Curves tools that give you precise control over your footage’s color balance. You can adjust the individual color channels (Red, Green, and Blue) or use the Custom Curves to fine-tune contrast and brightness in specific areas of your footage.

4. Refining with Nodes

For advanced users, DaVinci Resolve offers a node-based system where you can apply multiple LUTs, each on different nodes, and then adjust them individually. You can use serial nodes for simple adjustments, or parallel nodes for more complex multi-layer effects.

Step 4: Using LUTs for Specific Styles and Aesthetics

LUTs are not just for color correction; they can be used creatively to transform the look of your footage. Here are some ways to use LUTs to enhance your footage’s style:

1. Vintage or Retro Look

For a nostalgic or retro feel, you can apply a Film Emulation LUT that mimics the color characteristics of old film stocks. These LUTs tend to lower contrast and add a slight color shift, making the footage feel like it was shot decades ago.

2. Cinematic Looks

If you’re aiming for a cinematic or dramatic effect, apply a Creative LUT that enhances contrast and brings out deep, rich colors. Many cinematic LUTs increase the contrast in the shadows and add a soft, faded look to the highlights.

3. Black and White Conversion

You can also use LUTs to convert your footage to black and white while retaining the correct luminance values. By using a monochrome LUT, you can ensure that your footage still has the proper tonal range, which will make the black-and-white effect feel more dynamic.

Step 5: Advanced LUT Techniques and Tips

Once you’ve mastered the basics of using LUTs in DaVinci Resolve, you can take your color grading to the next level with some advanced techniques:

1. Layering Multiple LUTs

You can combine multiple LUTs to create a unique look. For example, you could use a technical LUT to correct the footage’s color balance and a creative LUT to add a stylistic effect. By layering the LUTs on different nodes, you have full control over how they interact with each other.

2. Using LUTs for Day-to-Night Conversion

LUTs are perfect for converting daylight shots into night-time scenes. By applying a LUT that shifts the colors to a cooler tone and adding a few extra adjustments to the highlights, you can transform a bright, sunny shot into a moody, dark atmosphere.

3. Creating LUTs for Consistency

After applying color grading adjustments to one clip, you can save the settings as a custom LUT and apply it to other clips in your project. This ensures a consistent look across your footage, which is particularly useful for

long-form projects or when working on a series of videos that need to maintain a similar aesthetic.

4. Using LUTs with Adjustment Layers

Another advanced technique in DaVinci Resolve involves applying LUTs to Adjustment Layers. This method allows you to apply the same LUT across multiple clips, which is particularly useful in multi-clip timelines. Adjustment layers are ideal for projects that involve a lot of footage where you need uniform color grading. You can create an adjustment layer, apply the LUT to it, and it will affect all the clips beneath it, ensuring consistency throughout the project.

5. Experimenting with the LUTs in the Context of Different Lighting

Different lighting setups will affect the results of a LUT application. For example, LUTs that work well in natural daylight may not produce the same results in dim, tungsten-lit environments. It’s important to test LUTs across different lighting conditions and make adjustments as needed. You can use the Scopes (like the Waveform Monitor, Vectorscope, and Histogram) to evaluate how the LUT affects the shadows, midtones, and highlights in different lighting conditions.

Step 6: Troubleshooting Common LUT Issues

While LUTs are a powerful tool for color grading, they can sometimes present challenges if they are not applied correctly. Here are a few common issues and troubleshooting tips:

1. Over-saturation or Too Bright

If the LUT makes your footage look over-saturated or too bright, try adjusting the Gain or Lift in the color grading panel. You may need to reduce the intensity of the LUT by lowering the Mix slider or decreasing the brightness levels in the Curves panel.

2. Color Shifts

Sometimes, applying a LUT can lead to unwanted color shifts, especially if you’re working with footage that has already been color-graded or shot in Log. In these cases, it’s helpful to apply a technical LUT that corrects the color before applying a creative LUT for stylistic purposes. If you’re still encountering color shifts, adjust the Gamma or Lift levels to neutralize them.

3. Clip Mismatch

In cases where you’re working with clips from different cameras or color profiles, applying a single LUT to all the clips might not result in a cohesive look. In these cases, you might need to apply different LUTs to different clips based on their respective profiles. Ensure that each clip’s color profile is corrected before applying a LUT for creative grading.

Step 7: Saving and Exporting LUTs

Once you’ve perfected your color grading with LUTs, you may want to save your custom settings for future projects. DaVinci Resolve allows you to save LUTs that you have created or modified. Here’s how to save and export LUTs:

1. Saving Custom LUTs

If you’ve created a custom LUT by adjusting the settings in the Color tab (e.g., using color wheels, curves, and nodes), you can save this LUT for later use. To save the LUT:

  • Go to the LUTs Panel in the Color tab.
  • Right-click on the LUT you want to save.
  • Select Save LUT and choose a name and location for it.

2. Exporting LUTs for Other Software

You can export your LUTs for use in other software as well. For instance, if you’re working in a team and need to share your LUTs, exporting them as .cube files will allow others to use them in other programs like Adobe Premiere Pro, Final Cut Pro, or Avid Media Composer. To export a LUT:

  • Go to the LUTs Panel in the Color tab.
  • Right-click on the LUT and select Export.
  • Choose the file format (typically .cube) and save it to a location on your computer.
