9/11/2023 0 Comments H.265 video compressionOne study 1 indicated that in 2012, global content brands lost $2.16 billion of revenue due to poor quality video streams, and were expected to lose up to $20 billion through 2017 as a result of quality issues. This can have a significant negative impact on revenue for content providers. That is a huge amount of data – much more than the human eye can completely ingest in many scenarios – and begs the question: “given today’s infrastructure, how much will we have to compress the streams, and what’s the video going to look like?”Ĭonsumers are already used to the high compression ratios (and any accompanying artifacts) necessary for delivering video over wireless and mobile (H.264/AVC or H.265/HEVC), but there’s still a tipping point at which the consumer stops watching if the video quality is too poor. What caught my eye, though, was support for 10K video at 120fps. It will support a bevy of new features, including 48Gbps data rates, eARC enhancements, Game Mode variable refresh rates, and more. H.264 requires 32 Mbps internet speed to play 4K video, while HEVC only needs 15 Mbps to easily accomplish the same task.At CES 2017, HDMI Licensing announced the specifications for version 2.1, which is intended for release later this year. H.264 only allows for nine directions of motion, while H.265 can allow for 33 directions of motion.īandwidth Utilization: Compared with the H.264 codec, H.265 requires much less bandwidth. Intraframe Prediction: The intra-frame prediction function of H.265 is more detailed than that of H.264. Macroblock: H.264 can recognize macroblocks with a maximum size of 16 x 16 pixels, while H.265 can use macroblocks with a maximum size of 64 x 64 pixels, which can improve coding efficiency at all resolutions. With H.265, videos with the same visual quality take up only half of the space. H.265 is much better than H.264 because it offers some major improvements over the H.264 codec as follows.įile Size: H.265 encodes the same information with lower bitrates but the same video quality when compared to H.264, which means H.265 delivers a significantly better visual quality when compressed to the same file size or bitrate.Ĭompression Ratio: The compression rate of H.265 is almost twice that of H.264.

It supports resolutions up to 8192×4320, including 8K UHD. It is the successor to the widely used H.264 codec and has made some major improvements over that now-aging compression scheme.Ĭompared with AVC, HEVC can provide 25% to 50% better data compression under the same video quality level, or can significantly improve video quality under the same bit rate. H.265, also known as HEVC (High Efficiency Video Coding) and MPEG-H Part 2, is a video compression standard designed for the latest generation of high-resolution video. H.264 is best known as being the most commonly used video encoding format on Blu-ray Discs and it is widely used by streaming internet sources. H.264 is the successor to MPEG-2 Part and the H.264 algorithm can better reduce the bit rate. H.264, also called AVC (Advanced Video Coding), is a video compression standard based on block-oriented, motion-compensated integer-DCT coding that allows for the recording, compression, and distribution of digital video content.

Let’s find out the answers to these questions.
