What is H264 and H265?

H. 264 uses what are called macroblocks, processing units that span 4×4 to 16×16 pixels. H. 265 uses a newer block structure called coding tree units (CTUs), which can process sizes of up to 64×64 pixels.

What is H264 support?

H. 264 is a well-known video compression standard for high-definition digital video. Also known as MPEG-4 Part 10 or Advanced Video Coding (MPEG-4 AVC), H. 264 is defined as a block-oriented, compensation-based video compression standard that defines multiple profiles (tools) and levels (max bitrates and resolutions).

Is H265 better quality than H264?

Conclusion. In a word, the difference between H264 and H265 is video compression efficiency. H265 provides more efficient bandwidth and resources on both the encoding and storage devices (HDDs/SSDs) than H264.
