Following the opening of 4K resolution video and up to 120 frames of video submission, at the end of September, HDR10 video was launched at station B. What difference can the HDR10 video recently launched at station B make? How can I experience the improvement brought by HDR10 video? Let's understand through the article together.
Currently, station B supports 4K+120 frames+HDR10 video at the same time, which is a very high-quality online video. Among them, 4K resolution and 120-frame video are relatively easy to understand. 4K high-resolution means better picture details, 120-frame video means a smoother picture effect, and HDR10 is completely different from these two parameters.
What is HDR10?
HDR is the abbreviation of "High-dynamic-range" in English, which means high dynamic range. Usually when you take pictures with your mobile phone, you can see that there is an HDR mode in the camera. In some scenes with particularly obvious contrast between light and dark, the HDR mode can show the light and dark scenes more completely, providing rich details in both bright and dark parts. , The complex light environment can also easily take good photos.
HDR10 is actually a bit similar to the HDR function in cameras, except that HDR10 is a standard for video. Compared with ordinary video (SDR video), HDR10 video has a larger dynamic range and can record richer details.
The most obvious effect is that while the dark part of the HDR10 video screen retains rich details, the bright part will not cause serious detail loss due to overexposure, the light and shade are more layered, and the picture is transparent. HDR10 video also supports a wider color gamut and 10bit color depth, and the picture color performance is closer to reality, vivid and natural.
When playing HDR10 video, HDR10 technology will provide static metadata, including picture light and shade information in the video, so that it can better match the screen and present the best display effect.
What else is needed to experience HDR10?
With HDR10 video, if you want to truly experience HDR10 video effects, you also need equipment that supports the HDR10 standard. Because HDR10 is an open standard, it has a wide range of applications. Many TVs and mobile phones support the HDR10 standard. Use HDR10-capable equipment to play to feel the difference.
At present, many flagship mobile phones support the HDR10+ standard. HDR10+ is an upgraded version of HDR10. While retaining the advantages of HDR10, it also supports dynamic metadata processing, which can provide signals frame by frame, and find the most suitable picture display parameters for each frame. , So that every frame of the picture can show the best effect. Compared with HDR10, it only supports static metadata, but the actual effect is still far better than ordinary video.
Because the HDR10+ standard is backward compatible with the HDR10 standard, mobile phones that support HDR10+ can also present HDR10 video effects.
Mainstream flagship mobile phones such as OPPO Find X2 series, Mi 10 Extreme Commemorative Edition, OnePlus 8, and vivo X50 Pro have all passed HDR10+ certification. Because these flagship mobile phones basically use OLED screens, OLED screens can achieve pixel-level control, display black more pure, greatly improve the contrast, can more perfectly present the brightness of different areas, and bring better display effects.
A 4K+120 frames+HDR10 official demo video was launched at station B this time. Through this video, you can experience the characteristics of HDR10 video. Most of the scenes in the demo video have complex lighting effects, including special effects of light and shadow, etc. It is easier to show the advantages of HDR10 in complex lighting scenes.
We use the HDR10+ certified Reno4 Pro for experience, and choose HDR true color quality playback (this quality can only be selected if the device supports it). The look-and-feel improvement brought by HDR10 video is obvious. When playing HDR10 video, the picture contrast is obviously higher and the picture is more transparent. Especially in some complex light scenes, while the dark parts are natural, the highlights are not overexposed.
There is a scene in the video at the end that is particularly obvious. From the comparison chart above, you can see that the text in the ordinary 4K video playback screen is not clear because of overexposure, and the details are seriously lost. When watching HDR10 video, the overall picture does not have that overexposed feeling, the font details are much richer and clearer, and the overall look and feel is very good.
to sum up
For most users, the device threshold for experiencing HDR10 video is not high. In addition to most flagship phones supporting HDR10+, some mid-range phones also support it. The combination of HDR10 standard equipment and HDR10 video can make it easy for users to feel the improved picture quality, and the picture is more real and natural. The picture quality upgrade brought by HDR10 video is very obvious.
At present, HDR10 video is still relatively small, and it is difficult for users to have HDR10 equipment to achieve real effects. Station B's support for HDR10 video this time will undoubtedly play a major role. In the future, we can more easily experience the improvement brought by HDR10 video. If your device also supports playing HDR10 video, you might as well experience HDR10 video.
