In recent years, we have witnessed breakthroughs in video playback technology as a result of the increasing popularity of videos. A video codec is an example of such technology, essential for a fluid watching experience. Currently, H.264 and H.265 are two of the most widely utilized video codecs. H.264 vs H.265, which one is better and what’s the difference? Let’s find out the answers in this blog.
What Is H.264 Codec (AVC)?
We’ve all experienced it: watching a movie, sports event, or Internet video when all of a sudden the screen freezes or the quality degrades. This sudden drop in quality is really annoying no matter what you’re watching. That’s why video codecs come into daily use.
The most widely adopted video compression standard at the moment is H.264, often known as “Advanced Video Coding” (AVC) or MPEG-4 Part 10. It was first made available in 2004 as a significantly improved version of its forerunners.
H.264 has the ability to significantly reduce video bitrates without largely lowering the video quality compared to earlier codecs. Exactly because of this highly efficient video encoding, H.264 has become the most popular codec ever.
Almost all current protocols, such as RTSP (Real Time Streaming Protocol), HLS Streaming, MPEG-DASH, HDS Streaming, and others, support H.264.
What Is H.265 Codec (HEVC)?
H.265 is a more recent video compression standard and, in many aspects, an improvement over H.264. It is also known as “High-Efficiency Video Coding” (HEVC) or MPEG-H Part 2. It was released in 2013, but it still has a long way to go before it is as well-known as AVC.
Higher efficiency necessitates better (and more costly) hardware than HEVC’s predecessor. As a result, rather than the general population, professional broadcasters and streamers still use it the most.
Today’s most popular video streaming protocols, such as HLS, MPEG-TS, and RTSP, all support H.265.
H.264 vs H.265: What’s the Difference?
It’s time to compare them now that we’ve gone over the fundamentals of each of these codecs. Here is a side-by-side comparison of H.264 vs H.265.
|Supported Video Formats||mkv, mp4, qtff, asf, avi, mxf, ps, ts, m2ts, evo, 3gp, f4v||mkv, mp4, qtff, asf, avi, mxf, ps, ts, 3gp|
|Bandwidth Required for Video Encoding||480p — 1.5 Mbps |
720p — 3 mpbs
1080p — 6 Mbps
4K — 32 mbps
|480p — 0.75 Mbps |
720p — 1.5 mpbs
1080p — 4 Mbps
4K — 15 mbps
|Required Bandwidth for 4K Broadcasting||32 mbps||15 mbps|
|Intraframe Prediction||9 modes||35 modes|
|Motion Compensation Technology||Vector prediction||Advanced vector prediction|
|Color Depth||8 bit||10 bit|
You can probably infer from the table above that H.265 is generally superior to H.264. For both encoding and transmitting, it uses half as much bandwidth as H.264 while maintaining the same level of visual quality.
Additionally, it employs more sophisticated prediction technology and contains 35 intraframe motion prediction modes, more than three times as many as AVC’s nine. All of this results in a far more effective method of video compression.
However, this does not imply that you should abandon H.264 and never look back. Despite how sophisticated H.265 codec is, it still has a number of problems.
First of all, the required gear is relatively expensive due to the computing power needed for HEVC to function. Because of this, H.265 codec is still not very common. This gap is made even wider by H.265’s rather poor device and browser compatibility. According to estimates, H.265 is supported by only 30% as many devices as H.264 and by fewer video file types.
Last but not least, you should be aware that the majority of online video platforms only accept H.264 if you intend to use an online video CMS to host, manage, and distribute your material.

So H.264 vs H.265, which one should you pick? Do you want to start live streaming from the comfort of your bedroom for content creation? Then H.264 ought to be sufficient for your needs. Do you work for a major broadcaster trying to streamline the streaming procedure? Then H.265 might offer you a better value for your money.
From my perspective, H.264 codec still rules as the industry standard and isn’t going anywhere, despite its slightly inferior performance. That’s all for the blog. If you have any questions or suggestions, please feel free to leave a comment below.
