In the World Video Encoder Competition hosted by Moscow State University on September 5, Kingsoft HEVC Encoder (hereinafter referred to as KSC265), the Kingsoft Video Cloud H.265 encoding software, ranked top in terms of multiple key indicators of video encoding. More importantly, KSC265 won the first place in terms of the video signal Peak Signal-to-Noise Ratio (PSNR), the most valued indicator in the video coding academic circle. This is the second time after Kingsoft Video Cloud KSC265 won the first prize in this competition in 2016, which fully demonstrates Kingsoft Video Cloud’s abundant technological accumulation and a leading position in the industry.
The World Video Encoder Competition is the most authoritative and influential top event in the industry, and is famous for its scientific selection to videos, rigorous testing methods and fair & open test reports. Both open-source encoders X264 and X265 have established their positions in the industry through this competition. Participants to this year’s competition include well-known enterprises such as Google, Intel, Kingsoft Cloud, Huawei, and Tencent. Enterprises competed against each other in the "arena" of video coding, and the competition was fiercer than previous years.
Again，Kingsoft Cloud has achieved great success this time. As early as in August 2016, Kingsoft Cloud KSC265 ranked first in terms of software encoders in the competition. Then in December of the same year, Kingsoft Cloud came first again in the 4K encoding contest. In this year's competition, Kingsoft Video Cloud not only got the first place in terms of the classic indicator, video signal Peak Signal-to-Noise Ratio (PSNR), but also performed excellently in Video Multi-method Assessment Fusion (VMAF) and the structural similarity (SSIM) of video signals, which embodied the fact that Kingsoft Cloud's video encoding technology has continued to be internationally acknowledged.
Kingsoft Cloud Wins the First Prize in Video Signal Peak Signal-to-Noise Ratio (PSNR)
Kingsoft Video Cloud KSC265 has been leading the industry all the time. Apart from winning the international award, Kingsoft Cloud took the lead by realizing the implementation of KSC265 in multiple application scenarios such as PC live broadcasts, mobile live broadcasts, short videos, etc. It is particularly worth mentioning that Kingsoft Cloud is the only cloud service provider in the industry who supports H.265 PC browser decoding plan and mobile real-time encoding plan.
