BDBR stands for Bjontegaard Delta Bitrate. If you have ever engaged in video coding quality analysis and compared different codecs, you have likely used rate-distortion or RD curves. Since the X-axis represents bitrate values and the Y-axis represents a quality metric, a higher curve indicates the codec encodes with higher quality at the same bitrate. […]
Read MoreLet’s examine how Intel encodes on modern graphics cards. My previous experience was entirely unimpressive, starting from building the source code and preparing for encoding in general. An embarrassingly large amount of time was spent on what seemed like a simple task. We even had to involve system programmers just to even get MFX working. […]
Read MoreWell, it’s time to write the first post! What this resource is about. As you might easily guess, it’s about comparing the quality of video codecs. On various forums and discussions, I often hear questions like, “I encoded a video using AV1, but the file ended up larger than the one compressed with H.264. Where […]
