H.264 vs H.265: A Complete Guide To Understand The Differences

Are you looking for the differences between H.264 vs H.265 video compression standards?

Dont Worry! we got you covered in this compression guide.

Without any further delay lets explore this.

The majority of the NVRs and DVRs available in the present times feature H.264 displayed or printed on their containers. The reality is, many top-quality videos streamed on the internet like Youtube make use of H.264 compression.

It is the process of video compression where motion in the encoded image is compared with stationary objects. This way, H.264 keeps all stationary things in the frame as a reference while simply recording the movement of objects.

It is only because of this reason that H.264 is considered one of the most fantastic recording processes for different surveillance videos. It is probably one of the most well-known video formats used for online streaming, recording and allocating video content on the internet.

Understanding H.264

Advanced Video Encoding or H.264 offers top quality video at a low bit rate and works more efficiently in comparison to the other standard video protocols like H.263, MPEG-4 part 2 and MPEG-2. However, H.264 requires two things to work properly.

First, the playback equipment should have the ability to decode H.264 videos back to playback video format. Second, the equipment capturing the videos should have the ability to encode the videos properly. MP4 or MPED Layer-4 and AVI or Audio Video Interlaced are the two common video formats playable in H.264.

Since H.264 does not have any standardized format with many companies holding varied patents, security camera systems can encode their H.264 in different ways. It is only because of this reason that all the security systems have their very own generic files for H.264 compressed videos.

Understanding H.265

High Efficient Video Coding or H.265 is a brand new standard in video compression, providing more improvement and features over H.264.

It offers a better bit reduction, which is 57% at 1080p with the UHD being 64%. Since all the devices in these present times, starting from smart TVs to Smartphones, display, and record at higher resolutions, having HEVC compression has become all the more important. The majority of the well-known video streaming sites have their videos encoded to H.265.

H.264 vs H.265: Difference Between Them

H.264 uses a motion-compensation-based, block-oriented video compression protocol for processing video frames. These units are known as macroblocks. They contain 1616 pixel samples, and you can even subdivide them into different transform blocks.

The transform slabs can further be sectioned into prediction units. All this might sound a bit confusing, but the fact is that H.264 lowers bit rates substantially and is widely used by some of the most popular video streaming sources on the internet. These include videos from YouTube, Vimeo, and iTunes.

Still, confused? Watch out below mentioned Video Formats, Codecs and Containers (Explained) video, it will help you to understand differences between H.264 vs H.265.

Features that Make H.265 Different

To start with, H.265 is the latest video streaming protocol and is thus more advanced in comparison to H.264. One major difference lies in that H.265 makes way for the reduced size of the file and thus needed reduced bandwidth for streaming videos live.

Dissimilar to H.264 macroblocks, HEVC processes information in CTUs or Coding Tree Units. Where macroblocks can range between 44 and 1616 block sizes, Coding Tree Units have the ability of processing as many as 6464 blocks, offering it the potential of compressing information most efficiently.

H.265: How is it better for Live Video Streaming?

Live video streaming is something that has gained huge popularity in recent times, and it is here to stay. The industry is fast marching towards high image and high bitrate quality formats.

The process is fast spanning Facebook, YouTube, individuals and different social media advocates including mid-sized and small organizations, professional broadcasters, sports franchises, and businesses.

Thus, while the world prepares for the demand for live video streaming and major technical issues of 4K live video streaming, it has become essential to invest in podiums that have the potential of delivering superior quality 4K live video streams.

Not only this, but the 4K live streams should also speak of reliability, technical sophistication, and simplicity, and this is only possible with the use of H.265. Ideally, HEVC or H.265 allows users to conveniently stream live events and videos without using huge network bandwidth.

H.264 vs H.265: Features that Make H.265 Better

H.265 provides some of the most significant improvements and features over H.264. Some of the major highlights for the consumers are as follows:

Improved Compression:-

HEVC or H.265 provides hugely improvised compression in comparison to what users can get from H.264. This new codec can achieve almost double the compression achieved by H.264.

A video with excellent quality visuals will take just half the space in H.265 as compared to H.264. In the same way, a video of similar bitrate and file size would be better looking significantly. This improvement in H.265 comes from an increase in the size of macroblocks.

Better Intra-Frame Movement Prediction:-

The process of video compression is entirely dependent on the prediction of movement between frames. Any video codec will be able to save space when there are no changes made in pixels.

So, better movement prediction automatically means better compression quality and file size. H.265 does not only speak of better standards of compression but even better motion compensation and prediction.

Parallel Processing:-

The H.265 codes make use of slices and tiles that you can easily decode from the remaining frame. Thus, the decoding procedure can easily be divided into several parallel procedure threads, grabbing the benefits of more effective decoding scopes on multi-core processors. This type of improvised efficiency and effectiveness is duly required with video resolutions getting higher.

More Complex Maximum Size of Frame:-

H.265 truly supports higher-res. With H.265, videos can conveniently be encoded at up to 8192 pixels x 4320 pixels or 8K UHD. At present, there are only a few cameras that can produce 8K videos.

Also, there are very few monitors that can display the same type of resolution. However, because HD is the standard of the present times, you can expect 4K and even 8K videos to rise in popularity.

Hardware Support:-

H.265 comes supported by Intel processors. The existing generation of processors come with special sets of directions for deciphering and programming H.265 videos. This offers H.265 major consistency and speed advantage over the other video codecs.

The Bottom Line

Despite the major improvisations of H.265 over H.264, the former is still not very common in the market. Nevertheless, it is gaining considerable market share rapidly. This video format is all set for Safari, and tvOS web browsers of Apple specifically meant for video streaming.
