To learn more about video compression, check out the articles in OTTVerse’s Video Compression series. ![]() And that the process of video compression will affect the video quality, and more often than not, reduce the video quality. We know that video compression is the process of reducing the size of a video either for storage or transmission requirements. The BD-Rate metric uses the information from the RD curves and tells you how much one codec has improved over the other.īut, first, let’s learn about RD Curves/Plots that are common in the field of video compression. When you evaluate a codec’s performance, you generally arrive at a rate-distortion (RD) curve that informs you about the quality (PSNR in dB) at different bitrates (typically, in kbps or Mbps). This article looks at the BD-Rate & BD-PSNR metrics and teaches how to calculate and interpret BD-Rate readings. BD-Rate and BD-PSNR are objective measures used in video compression to compare the rate-distortion performance or compression efficiency of two different video codecs or different settings of the same video codec over a range of bitrate or quality values. ![]()
