Obviously, two is better than one, and finally the encoding process can also take further advantage of multi-core processors. WMV consists of three distinct codecs: The original video compression technology known as WMV, was originally designed for Internet streaming applications, as a competitor to RealVideo. Parallel coding simply means that two separate parts of the image can be processed at the same time. Windows Media Video (WMV) is a series of video codecs and their corresponding video coding formats developed by Microsoft.It is part of the Windows Media framework. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders. These are basically encoding blocks necessarily large enough to handle the 4k of today and the, presumably, ubiquitous nature of 8k of tomorrow. AVCHD ( Advanced Video Coding High Definition) 1 is a file-based format for the digital recording and playback of high-definition video. CTUs, coding tree units, are essentially much larger ‘macroblocks’ that extend to 64×64 pixels while having the flexibility to go down to 4×4. your Avigilon Ava cloud IP cameras or to your existing cameras and sensors. Other technological advancements of H.265 are things like CTUs and parallel decoding. Leverage intelligent AI video analytics software for simplified management. For tests on 4K UHD, H.265 showed improvements at up to 64%! This means that if a H.264 1080p video 30fps needed 4Mb/s, the H.265 video with the exact same specs would only need 2Mb/s! Testing was done on a subjective and objective level, subjectively using test individuals to watch images and videos, and objectively by measuring things such as PSNR – peak signal-to-noise ratio. Thus far, testing has shown “substantial coding efficiency improvements.” In 92.5% of the test cases, HVEC produced even or superior quality at half the bit rate of AVC/H.264. So overall it’s rated between 10–35% more efficient. H.265 will generally lower the quality by about 10–15% to save about 40% of data compared to H.264.
