So for now, we have to take this benchmark as a future look into AMF's performance. This might be the reason why support is taking so long to implement. It's unclear why no one has implemented support for the update yet, but AMD does have a history of not broadly supporting developers in implementing its encoder SDKs. Support Is Still Largely AbsentĪs of now, the only problem with this new AMF encoder update is that no streaming platform has offered support, including OBS, despite the update being out for nearly four months. But basically, it means AMF's image quality is right underneath Nvidia's latest NVENC encoder right now, which is much much better than where it used to sit before the latest update. This benchmark can be difficult to understand. According to Code Calamity, AMD's AMF encoder is just half a point behind both those encoders, where as before (without B-Frames), AMD's AMF was a full two points behind. For reference, NVENC scores 96.13 points, and Intel QuickSync scored 96.37 in this test. In this benchmark, the highest possible score 100 is points. BenchmarksĬode Calamity used VMAF to measure the image quality differentiation between AMF, NVENC and Intel QuickSync, with Big Buck Bunny as the reference video. It is an optional feature, but one that has proven to significantly increase the image quality of streams at lower bit rates. B frames allow the H.264 compression algorithm to predict image data from both past frames and future frames in a video stream. These frames are paired with I and P frames to build a highly compressed video file. But AMD seems to have dropped support for it when the company released its new VCN engine, which was first released with AMD Raven Ridge APUs and RDNA1 graphics cards.ī-Frames are a very important aspect of video compression in the modern era. Ironically, AMD originally had B-Frame support with its original encoder and decoder engine VCE (starting with the 2nd gen implementation). The decisive feature improving AMF's image qulaity is the re-introduction of B-frames into the AMD encoder.
