Compare the picture quality between H265(HEVC) and H264

As VP9 encoder is a successor to VP8, H. 265 is also the new video compression standard after H. 264. Compared with the existing popular video coding standard H. 264, H.265 keeps some of the original technologies, and adopts the advanced techniques to improve the bit-stream, promote the coding quality, and create a better relationship between time delay and algorithm complexity, to achieve best optimizations as far as possible.

So what is the difference between H264 and H265 on earth? To make every reader understand the H.265 and H.264 intuitively, and make best use of them, I make detailed H264 vs H265 (as well as HEVC vs H264) comparisons on several aspects, such as compression ratio, quality and file size.

Bandwidth comparison between H.265 and H.264

1. H.265 vs H.264 Compression Ratio & Bandwidth Utilization

H.265 has better compression performance and lower bandwidth utilization ratio.

For video services, the ultimate goal of compressing a movie is to reduce the size of the movie file, so that it can take up less storage space, as well as reduce the network bandwidth consumption in transmission.

Compared with H. 264, the greatest strength of H. 265 is that it has a higher H.265 compression ratio, which can be just discerned from its name, which is also called HEVC (High Efficiency Video Coding), and the primary use is to further reduce the design flow rate, in order to lower the cost of storage and transmission.

In other words, at the same quality of coding, H.265 video can save around 50% of the bit rate, and the coding efficiency can be doubled than H. 264, as H.265 provides more different tools to reduce the bit rate. For example, in H. 264, each macroblock is fixed to the size of 16 x16 pixels, but the coding unit of H.265 can be chosen from a minimum of 8 x 8 to the maximum of 64 x 64.

2. H.265 vs H.264 Quality

0n the left hand side as the illustration shows above is using traditional H.264 standard, and each macro block is fixed; In H. 264 coding technology, the giant sections of data is completely independent to each other, so coding distortion situations are likely to happen in border areas of the giant block.

It is H. 265 standard on the right, the size of code unit is determined by the regional information. From the image contrast, we can see the video quality enhancement and the more delicate character’s skin under H. 265 are much better than H. 264.

3. H.264 vs H.265 File Size

From this H.264 vs H.265 comparison above, now we know well that how is H.265 superior to H.264. Without doubt, H.265 will become a widely used codec in the near future as it's really one of the best way to compress a video with original quality being remained.

So do you want to convert H.264 to H.265 or any other formats to H.265 with maximum output quality? Actually all you need is an awesome H.265 video converter that enables you to transfer MP4, MOV, AVI, etc to H.264 or H.265 video.
