Today, streaming content platforms are similar Netflix, YouTube either Twitch they are the ones that dictate how we see content on our computers or other devices, and since there are several high-quality content, the bandwidth needed to force them to change the way they compress video arriving on our devices.
That is why, today, the H.265 or HEVC format is widely used in place of the previous H.264 high definition video format.
What is HEVC and for what purpose?
Hundreds of HEVCs mean that «High performance video coding, which translates to «best video performance». Therefore, a video code or sync method
It is also known as H.265 because it was originally issued as follower of H.264and It's a video shortcut -something so far- and that in front of its follower allows for double data compression with half bandwidth, which has the effect of maintaining high definition quality but considering the available space.
Thus, we can say that video that has been compressed using this standard H.265 or HEVC, will produce a quality equal to or higher than that compressed with H.264 and, in addition, has less room.
What benefits does it offer compared to H.264? What's better?
That the H.265 codec is better than the H.264 is pretty obvious and we've already told you: the quality is maintained or improved by taking up less space, so it's worth posting high definition videos on streaming platforms (if you watch Netflix using smartphone data, you'll let you know) .
In any case, the following benefits are summarized:
- The HEVC version allows 8K resolution up to 300 FPS (H.264 is limited to 4K at 60 FPS).
- It lasts half the space, because it puts the video to a very low level, while maintaining quality.
- H.265 videos have a few flaws and technical issues, so increase image quality.
- This level allows to split pixels of each frame into groups of different sizes to better adapt to the environment, through a process called Coding Tree Units. In this case, Information blocks can go in groups between 4 × 4 and 64 × 64, while H.264 only allows blocks up to 16 × 16.
- HEVC develop differentiation skills, and instead of using one and the next frame to compare details, use more. This creates consistent data between the frames for reuse, saving space and bandwidth.
- Finally, the HEVC too improves tracking. In other words, in images that are not completely static, it continues to use information from the previous frames as we have described with component algorithms.
