What Is H264?

H.264, also called AVC (Advanced Video Coding), is a video compression standard based on block-oriented, motion-compensated integer-DCT coding that allows for the recording, compression, and distribution of digital video content. Through this compression, the codec can maintain the same video quality despite using only half of the storage space.

H.264 is a new video codec standard that is capable of providing good video quality at substantially lower bit rates than previous standards, such as MPEG2, MPEG-4, etc. This format supports 4K and up to 8K Ultra High-Definition.
