Netflix Finds x265 20% More Efficient Than VP9 (streamingmedia.com)
Reader StreamingEagle writes (edited): Netflix conducted a large-scale study comparing x264, x265 and libvpx (Google-owned VP9), under real-world conditions, and found that x265 encodes used 35.4% to 53.3% fewer bits than x264, and between 21.8% fewer bits than libvpx, when measured with Netflix's advanced VMAF assessment tool. This was the first large-scale study to use real-world encoder implementations, and a large sample size of high quality, professional content.A Netflix spokesperson explained why they did the test in the first place; "We wanted to understand the current state of the x265 and libvpx codec implementations when used to generate non-realtime encodes optimized for OTT use case. It was important to see how the codecs performed when testing on a diverse set of premium content from our catalog. This test can help us find areas of improvement for the different codecs."
Clearly though, the image produced by mpeg2 is much superior to h265 much like records sound better than CDs.
mpeg2 uses gold bits, while h265 uses copper and aluminum.

Yes but Capacitance Electronic Discs have a much warmer picture, especially when paired with new old-stock cathode ray tube amplifiers.
