Understanding HDR and SDR

Imagine taking a photo of a bright sunny landscape.

  • With an SDR camera: The bright sky might appear completely white, and the shadows under trees might be completely black. You lose a lot of detail in both the very bright and very dark areas.
  • With an HDR camera, the sky would still be bright, but you'd be able to see the clouds and the sun clearly. The shadows under the trees would have detail, too, showing the shapes of leaves and the ground.

What is HDR?

SDR (Standard Dynamic Range): Like a camera with a limited range of light it can capture. It can't show very bright or very dark areas well.

What is SDR?

HDR (High Dynamic Range): Like a camera that can capture a much wider range of light. It shows bright areas clearly and also reveals details in the darkest shadows.

Reasons for HDR to SDR Conversion

HDR offers stunning visuals with vibrant colors and high contrast, but not all devices or platforms support it. Converting HDR to SDR ensures your videos can be properly viewed across a wider range of devices. Here are some reasons why you might need to do the conversion:

  • Device Compatibility: Older TVs, monitors, or smartphones may not support HDR. SDR ensures compatibility with more devices.
  • Smaller File Sizes: HDR files are larger. Converting to SDR reduces file size, making videos easier to store or share.
  • Platform Limitations: Some streaming services or video platforms don’t support HDR. Converting to SDR ensures consistent playback.
  • Better Color Display: HDR colors may look unnatural on non-HDR displays. SDR adjustments make the video look more balanced and natural.
  • Improved Viewing Experience: In some cases, HDR can be too bright or saturated. SDR provides a more pleasant and consistent viewing experience.

Converting HDR to SDR makes your content more accessible, ensuring better compatibility and viewing on different devices and platforms.

Methods for HDR to SDR Conversion

Popular methods to convert HDR to SDR include Tone Mapping, Color Gamut, and Hybrid Conversion. Let's briefly understand them. 

1. Tone Mapping 

Tone mapping is a popular technique for compressing the dynamic range of HDR images to make them compatible with SDR displays. This technique maps the content's brightest and darkest parts to be in sync with the dynamic range of the SDR display. In the end, you get beautiful and detailed SDR content that is as good as the source (HDR content) file. 

2. Color Grading 

Color grading is used to adjust and match the color space of HDR content with SDR content. It uses a color look-up table to modify the color reproduction of HDR content to match with the SDR content. The end result of the SDR content colors is as beautiful and natural as the source file. 

3. Hybrid Conversion 

Hybrid conversion combines the Tone mapping and Color grading techniques by adjusting the dynamic range and color space of the HDR content so it is in sync with the SDR content. In the end, the SDR content not only has maximum details but also a natural color reproduction that gives a better viewing experience on the SDR display.

FAQs about HDR to SDR Converter

How does HDR differ from SDR?

SDR content has a maximum luminance of 100 cd/m2, while HDR has a wider contrast and color range, resulting in brighter images than SDR. You can see more incredible details and colors in scenes. HDR is superior in brightness (up to 1000 nits), color gamut (P3 and Rec. 2020), and color depth (8-bit to 12-bit) than SDR. 

Is the file size of SDR larger? 

Yes. While HDR content has better colors, quality, and clarity, it still has a smaller file size. HDR10 files have HVAC, an efficient file compressor, that helps generate smaller files without losing quality. On the contrary, SDR files are uncompressed, so the file size is naturally larger. 

Can YouTube convert HDR to SDR?

Once you upload your video to YouTube, the platform supports all video resolutions and auto-converts HDR to SDR when required. It detects HDR metadata and automatically processes it to generate HDR transcode for HDR devices and SDR downscale for standard devices and displays.
