This article dives deep into the H.264 vs H.265 debate, exploring their features, benefits, and use cases.
By the end, you’ll clearly understand these codecs and be equipped to decide which one suits your requirements.
Whether you’re a content creator, a streaming platform, or a tech-savvy enthusiast, understanding the differences between H.264 and H.265 is crucial in maximizing video quality, reducing bandwidth usage, and optimizing streaming efficiency.
Let’s delve into the world of video codecs and unlock the secrets behind H.264 and H.265!
Understanding H.264
Advanced Video Encoding or H.264 offers top-quality video at a low bit rate and works more efficiently than 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 be able 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 has no standardized format, with many companies holding varied patents, security camera systems can encode their H.264 differently. Because of this, all the security systems have their 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, 57% at 1080p, with the UHD being 64%. Since all the devices in these present times, from smart TVs to Smartphones, display, and record at higher resolutions, having HEVC compression has become all the more important. Most 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 16×16 pixel samples; 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 for mentioned “Video Formats, Codecs and Containers (Explained)” video, it will help you to understand the 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 than H.264. One major difference is that H.265 makes way for the reduced file size 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 4×4 and 16×16 block sizes, Coding Tree Units can process as many as 64×64 blocks, potentially 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 to deliver 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 compared 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 visuals will take just half the space in H.265 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 video compression process depends entirely 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 use slices and tiles 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 improvised efficiency and effectiveness is duly required, with video resolutions increasing.
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, very few monitors 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 comes 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.
H.265 vs H.264 – A Comparison of video codecs
In the realm of video compression, H.265 and H.264 stand as two formidable contenders vying for dominance.
These cutting-edge codecs have revolutionized video streaming, catering to the increasing demands for high-quality content with efficient bandwidth utilization.
To fully grasp their nuances and make informed choices, let’s delve into the depths of this H.265 vs H.264 showdown.
H.264, also known as Advanced Video Coding (AVC), reigned supreme for years, offering significant improvements over its predecessors.
With its adaptive algorithms and advanced motion estimation techniques, H.264 packed a powerful punch. It became the go-to video-stream codec, ensuring seamless playback on various devices.
However, the need for further advancements birthed H.265, or High-Efficiency Video Coding (HEVC).
Building upon the foundation laid by H.264, H.265 upped the ante by leveraging more sophisticated techniques like Advanced Motion Vector Prediction and Enhanced Transform Coding. These advancements significantly improved compression efficiency, enabling higher video quality at lower bitrates.
One of the main differences between these codecs lies in their compression capabilities. H.265 outshines H.264 in bitrate reduction, efficiently encoding video streams while maintaining exceptional quality.
This makes H.265 ideal for streaming high-resolution videos over bandwidth-constrained networks.
While H.265 offers remarkable benefits, widespread adoption has been slower due to its higher computational requirements for encoding and decoding processes.
This is where H.264 shines, as its encoding and decoding efficiency remain unmatched. It continues to dominate industries where real-time encoding and low latency are paramount, such as video conferencing and live broadcasting.
In conclusion, the H.265 vs. H.264 debate revolves around finding the right balance between compression efficiency and computational demands.
H.265’s superior compression capabilities make it a frontrunner for delivering high-quality videos over limited bandwidth.
On the other hand, H.264’s widespread compatibility and efficient decoding make it a reliable choice for real-time applications.
As technology advances and devices become more capable, H.265 is steadily gaining ground, driving the future of video streaming toward a new era of remarkable visual experiences.
Whether you prioritize compression efficiency or real-time encoding, understanding the distinctions between H.265 and H.264 will empower you to make informed decisions tailored to your streaming needs.
