HDR improves video quality to show a more realistic image. Read on to learn about two HDR solutions and how to use them.

Streaming technology has improved significantly, giving rise to higher and higher video resolutions from those at or below 480p (which are known as the standard definition or SD for short) to those at or above 720p (high definition, or HD for short).
The video resolution is vital for all apps. Research that I recently came across backs this up: 62% of people are more likely to negatively perceive a brand that provides a poor-quality video experience, while 57% of people are less likely to share a poor-quality video. With this in mind, it’s no wonder that there are so many emerging solutions to enhance video resolution.
One solution is HDR — high dynamic range. It is a post-processing method used in imaging and photography, which mimics what a human eye can see by giving more details to dark areas and improving the contrast. When used in a video player, HDR can deliver richer videos with a higher resolution.
Many HDR solutions, however, are let down by annoying restrictions. These can include a lack of unified technical specifications, a high level of difficulty in implementing them, and a requirement for videos in ultra-high definition. I tried to look for a solution without such restrictions and luckily, I found one. That’s the HDR Vivid SDK from HMS Core Video Kit. This solution is packed with image-processing features like the optoelectronic transfer function (OETF), tone mapping, and HDR2SDR. With these features, the SDK can equip a video player with richer colours, a higher level of detail, and more.
I used the SDK together with the HDR Ability SDK (which can also be used independently) to try the latter’s brightness adjustment feature and found that they could deliver an even better HDR video playback experience. And on that note, I’d like to share how I used these two SDKs to create a video player.
