A new video codec standard, the H.265 has been finalized and will succeed the popular H.264 as it uses half the bit rate, yet offer better video quality. The H.264/MPEG-4 AVC (Advanced Video Coding) standard currently the best known video file-format, and is the codec standard for High Definition across platforms like Blu-ray Discs, online video streaming and HDTV broadcasts. The H.264 codec was standardised for high quality videos as it provided good video quality at lower bit rates than H.263 or MPEG-2.
The H.265 HEVC standard will feature double the data compression ratio of H.264 and support resolutions up to 8192x4320 (8K UHD). This means streaming of high quality videos (which accounts for 80% of online videos worldwide) will now be easier on low bandwidth networks. For context, even the 82-inch 4K UHD TV isn't widely available yet. So its main application will be in making current video sizes even smaller. If you had to download a 170 MB (mkv) file per TV episode from your legitimate video provider, the same could now be achieved with just an 85 MB video file. You could potentially rip your Blu-Ray
discs for backup at a sufficiently good quality of video detail, and yet have a file size of only 700 MB
