In this camera recording NVENC clearly stands out from the x264 presets. The overall picture quality is good.
Also in this camera shot NVENC achieves the best value. The overall picture quality is very good.
Nvidia’s NVENC performs better than x264 medium in eight of eleven sequences. The values of medium, fast and veryfast are very close together and veryfast gives significantly worse results in all cases. Thus, a comparison of NVENC with x264 medium is reasonable from a qualitative point of view. If we look at the evaluation of the VMAF results, we can see that NVENC performs exceptionally well and even surpasses H.264 medium in quality. Medium, fast and faster have very similar scores, veryfast is with a value of 75.41 qualitatively clearly worse, you can see clear artifacts in the visual test.
