Is H.264 AVC “better” than H265 HEVC ?
Under what conditions can H.264 outperform H.265?

  Under what conditions can H.264 outperform H.265? Generally, newer video compression standards will offer performance advantages compared to existing ones. For example, H.265 HEVC is known to be 40% more efficient than H.264 with the cost of 10x more complexity. A NETINT customer observed under some circumstances H.264 AVC can outperform H.265 HEVC. The […]
