MSU Codec Comparison aims to deliver high quality comparisons of video encoders to both industrial and scientific communities. Since 2003 our team publishes annual reports with codecs’ comparisons.

HEVC Codec Comparison

Testing Objectives

The main goal of this report is the presentation of a comparative evaluation of the quality of new HEVC codecs and codecs of other standards using objective measures of assessment. The comparison was done using settings provided by the developers of each codec. Nevertheless, we required all presets to satisfy minimum speed requirement on the particular use case. The main task of the comparison is to analyze different encoders for the task of transcoding video—e.g., compressing video for personal use.

Testing Rools

The comparison was performed on two platforms:
  • Desktop—Core i7 4770R @3.9 GHz, RAM 4 GB, Windows 8.1
  • Server—Xeon E5 2697v3, RAM 64 GB, Windows Server 2012
  • For both platforms we considered three key use cases with different speed requirements.
  • Desktop
    • Ripping—no minimum speed
    • Universal—minimum 10 FPS
    • Fast transcoding—minimum 30 FPS
  • Server
    • Ripping—no minimum speed
    • Universal—minimum 30 FPS
    • Fast transcoding—minimum 60 FPS
  • Overall Conclusions

    Overall, the leaders in this comparison are x265, Intel MSS Hevc and x264! Enterprise and free versions of report are available here. Here are some overall graphs from report:
    Speed/Quality trade-off for Riping use-case (Y-SSIM metric)
    Average bitrate for Fast transcoding use-case (Y-SSIM metric)
    Average bitrate for Fast transcoding use-case (Y-SSIM metric)
