H.264, also known as Advanced Video Coding (AVC), has long been the dominant video compression standard. Today, most live streaming platforms use H.264 for playback, and more than 90 percent of video industry developers still choose H.264 as their codec. But in recent years, H.265 or High Efficiency Video Coding (HEVC) has generated a lot of buzz.
Not sure which video compression standard your production should use - H.264 or H.265? Read on to learn the differences between these two codecs.
The H.265 codec compresses information more efficiently than H.264, making video-quality equivalent files half the size of H.264.
The benefits of this are twofold: H.265 video files don't take up as much storage space and require less bandwidth to stream. This is a big advantage, especially when storing and streaming 4K video and other high-resolution video content.
The reason for this difference lies in the way each video compression standard handles frames. h.264 uses so-called macroblocks, which are processing units that span from 4×4 to 16×16 pixels. h.265 uses a newer block structure called the Coding Tree Unit (CTU), which can handle sizes up to 64×64 pixels.
The whole point of H.265 is to succeed H.264. so why isn't everyone using it?
The efficiencies offered by H.265 require more processing power. Not only does it require advanced hardware to create H.265 video files, it also requires decoding them for playback. This limits the ability to benefit from the superior efficiency of H.265 to only those with the right equipment. That's why H.264 remains the codec of choice for many.
Still, H.265 encoding has many advantages in today's video applications, especially those involving 4K. In addition, the number of content consumers with H.265-enabled hardware continues to grow, and it's only a matter of time before H.265 achieves its goals and replaces H.264.
