AMD AMF code was equal in quality to NVIDIA NVENC

NVIDIA After almost a decade, quite significant problems with quality AMD AMF coder received an update that radically changed the image quality thanks to B-Frames in AMF 1.4.24. The update itself, by the way, has been released for a long time, but only now it was tested well and compared directly with the latest NVIDIA NVENC.

It is worth noting that AMD had support for B-Frames in its original VCE code, but disappeared along with the VCN output. Frames B allow algorithms to predict these images based on past frames for future videos in the framework of stream. Code Calamity used VMAF to measure the difference in the image between AMF, Nvenc and QuickSync, and Big Buck Bunny was used for reference. The maximum score in this benchmark-100. For comparison, Nvenc is gaining 96.13, and QuickSync-96.37. AMD AMF is now gaining 95.39 points here, although earlier it was gaining only 94.12.

All these encoders, by the way, are still not able to catch up with X264 with a very slow preset, which is gaining 97.33. It is also worth noting that B-flime with AMF should also be supported by software used.
