Can I use Lumetri Color for HDR footage?

Yes, you can absolutely use Lumetri Color for HDR footage within Adobe Premiere Pro and After Effects. Lumetri Color is a powerful, integrated tool that supports HDR workflows, allowing you to grade and enhance your high dynamic range content effectively. You’ll need to ensure your project and export settings are configured for HDR.

Mastering Lumetri Color for Your HDR Footage

Working with HDR footage offers incredible visual fidelity, with brighter highlights and deeper shadows. Lumetri Color is your go-to solution within Adobe’s Creative Cloud for unlocking this potential. This guide will walk you through using Lumetri Color for HDR, from project setup to final export, ensuring your high dynamic range content shines.

What is HDR and Why Use Lumetri Color?

High Dynamic Range (HDR) video captures a wider range of luminance compared to standard dynamic range (SDR). This means more detail in both the brightest and darkest parts of your image. Lumetri Color is designed to handle these expanded color and light ranges, offering intuitive controls for color correction and creative grading.

Using Lumetri Color for HDR allows you to:

• Preserve highlight detail: Avoid clipping bright areas.
• Enhance shadow information: Reveal details in dark scenes.
• Achieve a wider color gamut: Take advantage of Rec. 2020 and other HDR color spaces.
• Create visually stunning content: Deliver a more immersive viewing experience.

Setting Up Your Project for HDR in Premiere Pro

Before diving into Lumetri Color, proper project setup is crucial for HDR workflows. Incorrect settings can lead to washed-out images or banding.

Project Settings for HDR

In Premiere Pro, navigate to File > Project Settings > General. Under the Video Rendering and Playback section, ensure your Renderer is set to Mercury Playback Engine GPU Acceleration (CUDA or Metal). This leverages your graphics card for smoother performance.

Crucially, your Color space should be set to an HDR-compatible option. Common choices include:

• Rec. 2020
• Rec. 2100 PQ
• Rec. 2100 HLG

The choice between PQ and HLG depends on your delivery target. PQ (Perceptual Quantizer) is common for mastered HDR content, while HLG (Hybrid Log-Gamma) is often used for broadcast.

Sequence Settings for HDR

Create a new sequence (File > New > Sequence). In the Sequence Settings tab, under Video, ensure your Preview File Format is set to an appropriate codec like QuickTime with ProRes 422 HQ or DNxHR HQX. Set your Color space to match your project settings (e.g., Rec. 2020).

Leveraging Lumetri Color Panels for HDR Grading

Once your project and sequence are set up, you can begin grading using the Lumetri Color panel. You’ll find this panel under Window > Lumetri Color. It offers a comprehensive suite of tools organized into logical sections.

Basic Correction for HDR

The Basic Correction tab is your starting point. Here, you’ll adjust exposure, contrast, highlights, shadows, whites, and blacks.

• Exposure: Controls overall brightness.
• Contrast: Adjusts the difference between light and dark areas.
• Highlights/Shadows: These sliders are particularly important for HDR. They allow you to recover detail in the extreme ends of your image without affecting mid-tones as much as traditional controls.
• Whites/Blacks: Set the absolute white and black points for your image.

When working with HDR, be mindful of your display’s capabilities. If you have an HDR-capable monitor, you can use its built-in HDR scopes. If not, you’ll need to rely on software scopes and export to an HDR display for final checks.

Creative Adjustments in Lumetri

The Creative tab allows you to apply LUTs (Look-Up Tables) and adjust intensity. For HDR, it’s best to use HDR-specific LUTs or apply SDR LUTs with caution, adjusting the Intensity slider to avoid crushing highlights or shadows.

Color Wheels and Match

The Color Wheels & Match section provides powerful control.

• Color Wheels: Adjust the color balance of shadows, mid-tones, and highlights independently. This is essential for fine-tuning the look of your HDR footage.
• Match Source: Can help in matching the color and tone of different clips, though manual adjustment is often preferred for creative control.

Curves for Precision

The Curves section offers granular control over your image’s tonal range.

• RGB Curves: Adjust the red, green, and blue channels independently.
• Hue Saturation Curves: Modify specific color ranges.
• Luminance Curves: Precisely control brightness across the image.

For HDR, the Lumetri HDR Tone Mapping effect (found under Effects > Color Correction > Lumetri HDR Tone Mapping) can be invaluable. This effect allows you to map HDR content to an SDR display or to a different HDR display with varying peak brightness capabilities. You can also use it to adjust the overall HDR look.

Exporting Your HDR Footage

Exporting correctly is as vital as grading. You need to ensure your export settings preserve the HDR information.

Export Settings in Premiere Pro

Go to File > Export > Media.

• Format: Choose H.265 (HEVC) or QuickTime.
• Preset: Select a preset that supports HDR, such as HDR 10-bit.
• Video Tab:
  • Profile: Set to Main 10 for 10-bit color.
  • Level: Choose an appropriate level (e.g., 5.1 or 6.1).
  • Color Space: Ensure this is set to your project’s HDR color space (e.g., Rec. 2020).
  • HDR Graphics: Check this box if available and applicable.
  • Max Luminance/Max Content Light Level: These values are important for HDR metadata. Consult your delivery specifications for the correct values.

Key Considerations for HDR Grading

• Monitoring: A calibrated HDR monitor is highly recommended for accurate grading. Without one, you’re essentially guessing.
• Scopes: Utilize HDR-aware scopes like the HDR Scopes panel in Premiere Pro. This includes Waveform, Vectorscope, and Histogram, all capable of displaying HDR luminance and color information.
• Bit Depth: Always work with and export in at least 10-bit color depth to avoid banding in your HDR footage.
• HDR Standards: Understand your target delivery standard (e.g., HDR10, Dolby Vision, HLG). This dictates your color space, metadata
