It will be time-consuming to encode video to H.265 in a low-end PC without GPU acceleration. Actually, in Handbrake H.265 encoding test, the quality of the H.265 video and the equivalent H.264 video are basically the same. But when playing HEVC video with VLC on PC, the 13.6% VLC Player was responsible for playing the H.265 encode. The 6.5% VLC Player was playing the original H.264 encode. So, if you only use CPU to encode video, I don’t recommend HEVC codec. Nevertheless, HEVC encoding on a high-end computer gives you smaller size, same quality comparing with Handbrake. And if your computer is geared with GPU-enabled graphics card, you also can get fast HEVC encoding speed.
In addition, one important point is that your HEVC encoder is able to encode video to H.265 utilizing NVIDIA CUDA & NVIDIA NVENC. StaxRip and Pavtube Video Converter Ultimate are excellent two H.265 encoder applications capable of hardware-based video encoding and can drastically decrease encoding time. Only if your computer has CUDA-enabled GPU, you can use StaxRip and Pavtube Video Converter Ultimate to convert video to H.265 at fast speed with the NVIDIA technology.
You can check the list below to see if your GPU is on your computer. If it is, it means your computer has a modern GPU that can take advantage of CUDA-accelerated applications.
