H.265 / HEVC Codec Tutorial

Author: John Honovich, Published on Jan 19, 2016

H.265 / HEVC has been promised for many years as the next big CODEC and the successor to H.264. Now with many H.265 IP cameras starting to ship, the market needs to decide on what to use.

In this tutorial, we break down the key issues including:

  • Technical Comparison Between H.264 and H.265
  • Potential Improvements in Quality
  • Limitations in Gains
  • Logistical Barriers in Moving to H.265
  • Motivations to Move to H.265
  • H.265 vs Smart H.264
  • H.265 IPVM Test Results

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.
