HEVC files are 8x8 to 64圆4 (Coding Unit) and intra: down to 4x4 (symmetric) inter 4x8 or 8x4 unl-directional, larger symmetric. MP4/H.2 64 files are 16x16 (Macroblock) in partition size and sub block down to 4x4. Because of the advanced and enhanced compress model of HEVC, which has 35 directional modes for intra prediction compared to 9 directional modes of MP4/H.264. What are the major differences between HEVC and MP4/H.264? The key improvement is that HEVC is 40-50% the bitrate reduction in the same visual quality compared to MP4/H.264.

HEVC just produces better video quality at lower space and bandwidth consumption, but instead it requires a higher demand in computing power than H.264 and other codecs.It is the reason that only limited online sites use the HEVC uploading method. HEVC codec is patented by a good number of parties and charged in higher licensing fee.But it is recommended to use H.264 as the best video codec for uploading videos to YouTube or other online sites. HEVC is used to compress video with 4K-resolution, and possibly even 8K-resolution in the future.Īs a successor of MP4/H.264, HEVC is compatible with the newer televisions support 4K and some sites. It processes information in what’s called Coding Tree Units (CTUs) that will compress video files to half the size possible using the most-efficient current encoding format. HEVC stands for High Efficiency Video Coding, which is also known as H.265.
