HDR is the abbreviation of High Dynamic Range. Dynamic Range refers to the number of gray levels between the brightest point and the darkest point in an image. Compared to SDR (Standard Dynamic Range), HDR allows you to see more of the details and colors in scenes. Nowadays, you may get HDR contents from mobile, camcorder, streaming services like YouTube, Netflix, or 4K UHD Blu-ray DVD. Once you've got your HDR content cued up, whether it be HDR video or and HDR game, you'll have to make sure your setup is capable of displaying that HDR content. If not, you may probably found the HDR video will lose its original color range and degrade color brightness & saturation. The whole video image would become grey. That's what we usually call washed-out color when we view the 4K HDR videos on an HDR unsupported display.
Actually, though HDR is being adopted by the general market with remarkable ease and speed, there are innumerable SDR TVs, monitors, projectors, desktop and phones that are still being in use. What if you want to play 4K HDR video on these SDR devices? Upgrading your hardware is one way to eliminate the washed-out color issue but this way is quite expensive. If you don't plan to do this, transcoding 4K videos from HDR to SDR could be the best choice. In this post, we will share you with the top 3 ways to convert 4K (HEVC) HDR to SDR video without damaging quality.

Note: If you know clearly that your clips are HLG or PQ variants of HDR, you can choose the more specific conversion options:
● HLG to Rec. 709 SDR
● PQ to Rec. 709 SDR
● PQ Output Tone Map
● HLG to PQ (Rec. 2100)
● PQ to HLG (Rec. 2100)
5. To set a clip's maximum luminance on a display to a specific level, drag the "Peak Brightness (nits)" slider, for example, to 1000 nits.
6. To optionally set the amount of the original image to be blended with the adjusted image, drag the Mix slider.
