Tencent Cloud Recognized as Top Performer in Video Encoding by International Authority Streaming Learning Center

Tencent Cloud's Media Processing Service is proven to have the best in quality and cost efficiency under the H.264 and HEVC per-title encoding standards

HONG KONG,Aug. 30,2022 -- Tencent Cloud – the cloud business of global technology company Tencent – today announced that its Media Processing Service (MPS) has been cited as the top performer in video encoding in two reports recently released by international professional streaming media technology blog Streaming Learning Center (SLC). With the exceptional performance compared to other cloud services providers,the recognition puts Tencent Cloud at the frontline in the key battlefield of encoding technology,which determines businesses' video quality,fluency and bandwidth storage cost.

Video Encoding: An Essential Tool in the Digital Era

Video encoding is an underlying core technology for compressing video files' digital information. It aims to save transmission and storage bandwidth while keeping the video's subjective quality. With the emergence and rapid development of 4K/8K video as well as the pressure on network bandwidth,encoding technology has become a key research area for most internet companies.

Based on the criteria measured by SLC in both its HEVC and H.264 per-title quality reports,Tencent Cloud was found to be the best choice for top heavy,mobile,and IPTV distributions. The HEVC and H.264 are the two most widely used codecs in the world,and both of SLC's reports comprehensively evaluated various key indicators in different scenarios,which include storage and encoding costs,streaming bandwidths,overall video quality and stability,ladder integrity and construction.

Figure 2. The bitrates of Tencent Cloud’s MPS are lower than others. It was the best in all three quality measures in overall H264 per-title comparisons.

Both reports highlight the exceptional performance of MPS,emphasizing that while there are multiple factors to consider when choosing cloud service providers,Tencent Cloud should be at the top of the list from a pure cost and quality standpoint. In terms of overall performance and quality,Tencent Cloud is the only cloud service provider to receive "excellent" rankings in all the three distribution patterns of the H.264 per-title report,as well as two distribution patterns of the HEVC per-title report. As for cost efficiency,SLC has also mentioned that Tencent Cloud is the most economic option at various points in both reports. The reports were designed to assist those companies in choosing a cloud encoding provider,particularly for per-title encoding capabilities,and are available for purchase at the Streaming Learning Center.

Poshu Yeung,Senior Vice President,Tencent Cloud International,said,"At Tencent Cloud,we strive to provide enterprises and organizations with the highest possible quality and performance in our services. The result of Streaming Learning Center's study is a testament to the hard work and dedication Tencent Cloud has put into our media solutions capabilities,and the high standards we have set for ourselves as a cloud service provider.
