AI Overview
H.265 (HEVC), H.264 (AVC), and MPEG-2 are video compression standards representing generations of efficiency improvements. H.265 is the most advanced, offering 50% better compression than H.264, making it ideal for 4K/8K, while H.264 remains the standard for web compatibility, and MPEG-2 is used for older formats like DVD.
This video explains the key differences between H.264 and H.265:

Is h264 better quality than MPEG-2?
Subjective testing results partially uphold the commonly held claim that H. 264 provides quality similar to MPEG-2 at no more than half the bit rate for the coding-only case. However, the advantage of H. 264 diminishes with increasing bit rate and all but disappears when one reaches about 18 Mbps.
