H.265 support has improved significantly since its introduction, with H.265 camera/VMS compatibility increased compared to only a year ago, and most manufacturers shipping H.265 models.
However, there are still challenges impacting H.265's competitiveness and compatibility, keeping it from replacing H.264 in the mainstream.
In this report, we review all these issues, including:
- H.264 vs H.265 Technical Comparisons
- Impacts On Quality
- Barriers in Moving to H.265
- Camera/VMS Compatibility Improvements
- VMS Support Reviewed
- ONVIF Conformance Delays
- 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.
