h264 and h265, Whats the Difference?

What’s the difference between h265 and h264?

Hello everyone, thanks for checking out today’s article. Today we’re going to be talking about compression codecs, specifically the two most common ones- h264 and h265. We often get asked, “what’s the difference between these codecs?” Well, to better understand the difference between h264, and h265 it helps to know what those terms are. Firstly know that both h264 and h265 are forms of video compression.

Video compression is essentially a series of programmed processes that allow a computer system that is doing video encoding to squeeze the video data into smaller file sizes than it normally would be naturally. The goal is for this to be accomplished without a substantial- if any- loss in quality. This is done using a combination of prediction and smart coding.  For a while, and even currently still H264 has been a fantastic compression method and is still widely the most popular. This is because H264 offers very good compression, with minimal loss in quality, and doesn’t tax an encoding system too hard.

However, as more and more devices are constantly streaming data over the web, and the quality of our video content becomes higher and higher in resolution, solutions beyond h264 are needed to maintain, or achieve even lower file sizes.

That’s where h265 comes into play. H265 is the newer iteration of video compression. It is able to achieve file size that are approximately 64% smaller at 4k, and 57% smaller at 1080p than the h264 counterpart. However, this comes at the cost of more processing power- h265 requires substantially more computing power to pull off without issue. Its also important to recognize that while many of the popular media players available are capable of h264 file playback natively and smoothly – many do not support h265 by default.

Fortunately, h265 is becoming more and more common, leading to more support- often by downloading and installing an h265 codec which can be used by a media player to decode and playback h265 compressed files. Many more players nowadays are supporting h265 natively. In fact, our in house media player called the Elite Smart Player has support for both h265 and DAV file playback natively- without the need for installing any additional codecs or software.
