H.265 / HEVC Codec Tutorial 2017

Author: John Honovich, Published on Jun 30, 2017

For years, video surveillance professionals have talked about the potential for H.265.

Now, in 2017, H.265 is starting to gain mainstream adoption, with many manufacturers shipping cameras and some VMSes adding support. However, there are many issues impacting H.265's competitiveness and compatibility.

We cover:

  • H.264 vs H.265 Technical Comparisons
  • Impacts On Quality
  • Barriers in Moving to H.265
  • VMS Support Reviewed
  • No ONVIF Conformance Until 2018
  • H.265 vs Smart H.264
  • H.265 Smart Codecs
  • H.265 IPVM Test Results
  • H.265 CPU Load Impact
  • Patent Licensing Issues
  • Usage Recommendations

Overall, the key marketing claims for HEVC/H.265 is reducing bit rate requirements in half to deliver the same quality. For instance, if a 1080p / 30fps H.264 camera required 4Mb/s, the equivalent H.265 camera would be expected to require only 2Mb/s. But that is now, clearly not enough, as we will explain inside.
