HDR quality is pleasing and preferable for users as it displays clear, sharp, and high-quality images, which are lacking in SDR due to fewer details and colors. However, these details can cost you your storage space and may not run smoothly on old or some new devices. In such a case, you may decrease the video's resolution or convert HDR to SDR without compromising on the quality.

In this article, we will provide you with detailed information on the five best HDR to SDR converters to help you seamlessly convert your video files. We will also assist you with their advantages and drawbacks to help you decide which one to choose. Let's find them out one by one, but first, understand what HDR and SDR are and their differences

What is HDR


High Dynamic Range (HDR) is the newest technology to enhance video images and quality. It provides a better video-viewing experience with clarity and sharpness for detailed photos. HDR is preferred for videos that have high contrast, shadows, and mixed light. They offer a picture quality and color gamut that is as good as visible to the naked eye. There are many types of HDR; the common ones include Dolby Vision, HDR 10, and HDR 10+. You must know that HDR files require HDR-compatible devices to run smoothly. It includes modern media players, monitors, and smart TVs.

What is SDR

SDR, or Standard Dynamic Range, is a video standard in non-4K HDTVs or theatres. Some SDR displayers can display excellent image quality; however, they can't match the contrast of HDR. Many users prefer SDR over HDR as it consumes low disk space and is compatible with general devices.

Differences Between HDR Vs. SDR

HDR users can see higher details of images with greater clarity and sharpness. On the contrary, SDR users also have decent photos, but they are not as great as HDR, especially in terms of colors and details. However, there's more to HDR and SDR than image clarity and quality. Let's take a look at the differences between them. For more details, you can refer to this post: HDR vs SDR.

 

HDR

SDR

Level of Brightness

Up to 1,000/10,000 nits of brightness to bring more vibrant and varied imagery

Up to 100 nits of brightness

Depth of Color

Supports 10 or 12 bits per color to display billions of colors

Uses 8 bits per color, ~ 16.7 million colors

Contrast Ratio

Relatively high contrast ratio with a clear difference in the brightest white and darkest black parts

Relatively low contrast ratio makes a less distinct difference between dark and bright parts

Color Volume and Gamut

Wider color gamuts like Rec.2020 or DCI-P3 for more realistic and accurate colors

Covers small space with Rec. 709 for HD, making the color range limited

Detail Representation

Preserves the detail in dark and bright areas of the screen

Bright regions are overexposed, losing detail, and dark areas are underexposed, looking muddy

Equipment Compatibility

Requires specific hardware to display

Easily viewed on all screens without special hardware
