Hardware Qsv Vs Software X264. Your Options Explained 2020 Update Posted on October 22 2020 October 23 2020 by Nick Small 18 mins read. As others have reported in various threads my testing shows enabling QSV hardware encoding h264_qsv results in only about a 30 faster encode but the resulting file is typically at least three times bigger than using CPU encoding with libx264.
In case both your hardware and software address the above requirements then youre able to utilize the Intel QSV CPU hardware acceleration to improve video processing speed. Ive used QHD 1440p 60fps Overwatch gameplay to test how a variety of codecs and encoders measure up using Netflixs VMAF quality assessment algorithm. Hardware decoding and encoding.
X265 x264 QSV NVEnc VCE X265x264 are CPUsoftware based encodings and quality wise better than GPU based encoders from Intel QSV NVIDIA NVEnc and AMD VCE.
Whats better this 4K video processing software supports various types of hardware decoding. 2018 was the year of the m2 NVME drive. If it is to make a rank for these CPU and GPU encodings the order should be. Does this mean you cant use hardware acceleration to speed up video transcoding.
