With you daily experience, you may find that although H.265 (HEVC) is the successor of H.264 (AVC), it is not as popular as H.264 among the market. What's more, it seems that the discussion between H.265 and H.264 is uninterrupted. What's the main difference of these two video codecs? What's the advantage of H.265? Why is H.264 not as good as H.265? Questions are here and there. In this article, we will show you an exhaustive comparison between H.265 and H.264.

Definition of H.265 and H.264

H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC) is a block-oriented motion-compensation-based video compression standard. It is widely used in Blu-ray discs, internet sources like videos in YouTube and iTunes Store, web software, as well as HDTV broadcasts over terrestrial, cable and satellite.


H.265 or MPEG-H Part 2, High Efficiency Video Coding (HEVC), is a video compression standard, designed as a successor to the widely used H.264 (AVC). It delivers higher quality video at the same bitrate as H.264. H.265 supports resolutions up to 8192×4320, including 8K UHD.

Comparison between H.265 and H.264

I will list out the difference between H.265 and H.264 in terms of file size, macroblock and compression ratio etc. to provide a clear comparison for  you.


File Size: Some previous studies showed that the bit reduction is inversely proportional to the video image quality and also positive to file 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.


Macroblock: H.264 provides support for 16 x 16-pixel macroblocks which are not work well in higher-resolution video. H.265 provides support for 64 x 64-pixel macroblocks, showing greater encoding efficiency at all resolutions.


Compression ratio: The compression ratio of H.265 is almost double that of H.264, which is able to further reduce the design flow rate so as to lower the cost of storage and transmission.


Intraframe prediction: The intraframe prediction function of H.265 is more comprehensive, that means H.265 can allow for 33 directions of motion while H.264 only allows for nine directions of motion.


Bandwidth utilization: H.265 requires much less bandwidth as compared to H.264 codecs. Actually, H.264 requires 32 mbps internet speed to broadcast 4K video while HEVC can easily do the same in just 15 mbps.


How to Convert H.265 to Other Formats and Vice Versa

As we know from the above comparison, H.265 is superior to H.264, but it is not very widely used by the market, because it's not completely supported by all popular devices. If you would like to enjoy H.265 video on your portable devices, you'd better convert H.265 into other formats to play on your devices.
