other hardware accelerated video processing solutions and invite you to evaluate yourself. We believe Intel HW+Media SDK is very competitive vs. There are internal evaluations but nothing in publishable form yet. PSNR/SSIM and other quality metrics can help but there is no substitute for golden eyes.Īs you may guess from these details competitive performance and quality is very important. An important tip for comparing quality is to look at the bitrate actually achieved, not just what was requested. Though when you buy an Intel CPU (besides the F variant) and or a GPU, you most the time get an onboard encoder/decoder that is a. NVENC remains the default with supported Nvidia GPUs, but somewhere in the Preference settings you must manually make the selection on first launch whether to use Nvenc (default) or QuickSync. Sample_multi_transcode par files can be set up with multiple lines to start multiple sessions simultaneously.įor PSNR/SSIM quality comparisons there are many options but one of my favorites is the psnr tool in libyuv. Ultimate Encoder Quality Analysis 2020 (NVENC vs AMF vs QuickSync vs X264) After far too many requests to updated my previous X264 vs NVENC and NVENC vs AMF/VCE videos with newer AMD drivers, Ive finally put together what I consider to be the ultimate package of encoder quality comparisons. Well today we compare the Intel Quick Sync UHD 770 vs NVENC. The hardware encoder selection became available with version 14.4. Transcode is a better test for hardware capabilities because encode and decode by themselves have significant raw I/O overhead. NVENC Video Encoder API Programming Guide ( PDF ) NVIDIA GPUs based on NVIDIA. Id be ok with using Intel Quick Sync though, the only one I would. Performance numbers for Media SDK can be obtained easily from its samples. NVENC does have lower latency than Intel Quick Sync, NVENC > Quick Sync in all regards. Standard quality comparisons like PSNR or SSIM have many limitations so "better" may be best left to your evaluation. This link may help with some of the data you're looking for: Īs you know, performance and quality comparisons are tightly coupled.
