Even while enjoying your favorite audio-video content on any of your favorite devices, you don't even care about any sort of technicality or technology involved in the process, unless and until you would use the best technology to convert any video from one format to another through the best video compression encoder. So, to talk about video compression codecs, H.264 and H.265 are the most commonly used standard encoders. However, to pick the best video converter using the most advanced encoder, you have to go through a detailed comparison between H.264 vs h.265.

Statistical states: This statistical chart and comparison chart explicitly imply that the successor encoder H.265 gives very tough competition to its predecessor encoder H.264.

h.264 vs h.265:


Before getting started with the comparison between H.264 vs H.265, let's have a brief idea about what these H.264 and H.265 are all about.


H.264 is the most commonly used video codec, which is a process to compress video from one format to another through encoding. So, being one of the most popular encoders, H.264 is also known as Advanced Video Coding (AVC) or MPEG-4 Part 10. This codec is mainly used for video recording, compression, and distribution.

H.264 is a successor encoder of MPEG-2 or H.263. More than 91% of developers from the video industry used the H264 encoder. This encoder is specially used to compress HD videos available in AVCHD camcorders, Blu-ray, HDTV, and HD DVD while maintaining high video quality in comparatively low bitrates. Mp4 is one of the most often used file formats encoded with H.264.

When it comes to the file compression process, there are multiple encoding algorithms available in the H.264 codec, but quality-enhancing and complex bitrate controlling codec techniques that are hard to decode are the most commendable ones.


H.265, or High-Efficiency Video Coding (HEVC), is also a video compression codec, a successor of AVC/ H264, and known as MPEG-H part 2. This encoder provides encoding support to Ultra HD Blu-ray format. The compression efficiency will vary depending on the content type and encoder settings.

The main purpose of developing H.265 is to excel the video compression efficiency of H.264 while maintaining the same video quality of H264 in the smallest video file with more compact codec technology. HEVC has been used by 43% of developers, and it has ranked in the second position after AVC.

Since both these H264 and H265 codecs work for the same purpose of video compression, a comparison is compulsory to evaluate the perfection and efficiency in their execution of the video compression process.

H.264 vs h 265 file size

To compare H.265 vs h 264 file size, H.265 will always come first, providing 25% to 50% more data compression benefits by reducing the bitrate while maintaining the same video quality as H.264. So, the file encoded with H.265 is almost half in size compared to H.264 while balancing the same image quality. And a small file always needs less storage space on your device. When H.264 handles up to 4K (4,096×2304) resolution, H.265 supports picture resolution up to UHD 8K (8192×4320).

H.265 provides improved high video quality while maintaining the same low bit rate. Unlike H.264, H.265 has incorporated higher fidelity Main 10 profile in almost all supporting hardware. So, in terms of H.264 vs H.265 file size, there is no doubt that H.265 is on the winning side by providing around 1 to 3X smaller video size than H.265. So, it's clear that in H.264 vs h 265, there is no doubt that H.265 is in the first place.

H.265 vs h 264 quality

To talk about any video compression process, the first thing we are concerned about is the video image quality. So, in the case of H.264 vs h 265 quality comparison, the main difference lies in how these codecs process the frame. H.264 uses the DCT ( Discrete Cosine Transform) with block sizes 4×4 and 8×8, and on the other hand, H.265 uses DCT and DST (Discrete Sine Transform) with block sizes from 4×4 to 32×32.

On the one hand, H.264 uses macroblock processing units that involve a picture frame span of 4×4 up to 16×16 pixels; on the other hand, H265 uses an advanced block structure called Coding Tree Units (CTUs) that can process span up to 64×64 pixels. Along with this, the motion compression and spatial prediction technologies are way more advanced in H.265 as compared to H.264.

The intra-frame prediction function is more detailed in H.265 as compared to H.264. On the one hand, only 9 directions of motion are allowed by H264; then, on the other hand, 35 directions of motion are allowed by H.265. So, in H.265 vs h.264 quality parameters, H.265 is way ahead.
