Summary: What are the differences between HDR and SDR? Here in this article, we will compare HDR and SDR and show you a tool to convert the HDR of 4K Ultra HD Blu-rays to SDR.

It doesn't mean that you have a 4K TV you'll enjoy the fullest 4K quality. This is because there are two types of 4K Video - SDR and HDR.

The similarity between the two is that they have 4000 lines of resolution.

Although both have the same number of horizontal resolution, their picture quality differs, however.

 

HDR VS SDR Comparison

Before we proceed, let's examine what SDR and HDR mean and their main characteristics.

 

HDR Explained

HDR means High Dynamic Range. HDR has been used in still photography before making its shift to TVs, smartphones and computer monitors, among others.

HDR promises a comprehensive color range, and picture quality that resemble what's seen by the naked eye. As a result you get increased overall image detail SDR doesn't promise these advantages.

To appreciate the importance of HDR, it's important to understand that images aren't captured as the eye sees them.

Images captured will be darker or brighter than what's visible to the eyes.

If an image is overexposed, the appropriate color info on the brighter parts is lost. Similarly when an image is underexposed, true color info on the darker parts are lost.

When HDR is applied to such images it calculates the amount of light in the image and the lost color information is restored. Thus we get realistic images with enhanced detail and depth.

The popular HDR standards are HDR 10 (introduced in 2015 and widely used), HDR10+ introduced in 2017, Dolby Vision (supports 12 bit color depth) and HLG (Hybrid Log-Gamma), also known as broadcast HDR.

 

SDR VS HDR: SDR Explained

SDR means Standard Dynamic Range. It’s the video standard you would have come across over your non-4K HDTV or cinema.

Although there are some high-end SDR television sets that displays excellent image quality they are no match for the contrast ratio that HDR offers.

High-end SDR however comes close to low-end HDRs with no noticeable difference in image resolution.

Now that you know the main differences between HDR and SDR, you can now prepare videos according to the 4K format that your television supports.

If you need lossless quality that's no different from the UHD Blu-ray you're ripping, you'll have to opt for MKV Passthrough or M2TS Passthrough.

If file size is a concern and you can do with medium quality opt for MKV.4K.H265.10bit or M2TS.4K.H265.10bit.
