Understanding HDR video technology – What is HDR Video?

HDR is also gaining traction in the gaming industry. Both gaming consoles and gaming monitors are supporting HDR, enhancing the realism and aesthetics of video games.

HDR, or High Dynamic Range, video is a technology that enhances the visual quality of video content by expanding the range between the darkest and brightest areas of an image. This increased dynamic range results in more lifelike and immersive viewing experiences.

Key aspects of HDR video technology

  • Dynamic Range: In standard dynamic range (SDR) video, the range between the darkest and brightest parts of the image is limited. This can lead to loss of detail in very bright or very dark areas, making the image look less realistic. HDR expands this range, allowing for more detail in both shadows and highlights.

  • Brightness and Contrast: HDR video features significantly higher peak brightness levels compared to SDR, making the bright parts of the image appear much more vivid. This increased contrast enhances the overall visual impact.

  • Color Accuracy: HDR also improves color accuracy by displaying a wider gamut of colors. This means that you can see more shades and nuances in colors, which adds to the realism of the image.

  • Local Dimming: Some HDR displays utilize local dimming technology to enhance contrast further. This means that different areas of the screen can be independently controlled to adjust brightness, resulting in deeper blacks and brighter highlights in the same frame.

  • Content Compatibility: To fully enjoy HDR video, you need both a compatible display (like an HDR-capable TV or monitor) and HDR content. Many streaming platforms, Blu-ray discs, and video games offer HDR versions of their content.

 

The Basics of Dynamic Range

Dynamic range is a fundamental concept in photography, videography, audio, and various other fields. It refers to the difference between the darkest and the brightest elements in an image, sound, or signal. Here are the basics of dynamic range:

 

Dynamic Range in Photography/Videography:

  • In photography and videography, dynamic range refers to the range of brightness levels that can be captured or displayed in an image or video.
  • A camera or sensor’s dynamic range is usually measured in stops, which are logarithmic units. Each stop represents a doubling or halving of the amount of light.

 

High Dynamic Range (HDR):

  • High Dynamic Range (HDR) imaging or video technology expands the dynamic range beyond what can be achieved with standard imaging or video techniques.
  • HDR captures or displays a broader range of brightness levels, resulting in more detail in both shadowed and highlighted areas.

 

Low Dynamic Range (LDR):

  • Low Dynamic Range (LDR) represents standard imaging and video that doesn’t employ HDR techniques.
  • In LDR, the dynamic range is limited, and some details in highlights or shadows may be lost or appear as pure white or pure black.

 

In Graphics and Displays:

  • In computer graphics and displays, dynamic range is important for rendering realistic images and videos on screens.
  • HDR displays can provide a more immersive viewing experience by showing a wider range of colors and brightness levels.

 

Compression and Expansion:

In some cases, dynamic range compression or expansion is applied to audio and video signals to make them more suitable for specific purposes, like broadcasting or playback.
