720P,,, 1080P adopts H.264 coding. What is code stream m?

20P is about one million pixels, and the code stream is about 2 to 4 or 5m.

1080P is about 4 to 8M.

H.264 is also the tenth part of MPEG-4. It is a high compression digital video coding and decoding standard proposed by Joint Video Group (JVT) composed of ITU-T Video Coding Expert Group (VCEG) and ISO/IEC Moving Picture Expert Group (MPEG). This standard is usually called H.264/AVC (or AVC/H.264 or H.264/MPEG-4 AVC or MPEG-4/H.264 AVC) and its two developers are clearly described.

Coding is the process of converting information from one form or format to another, also known as code abbreviation coding of computer programming language. Encode characters, numbers or other objects into numbers by a predetermined method, or convert information and data into prescribed electric pulse signals. Coding is widely used in computer, television, remote control and communication fields. Coding is the process of converting information from one form or format to another. Decoding is the reverse process of coding.

Data rate refers to the data stream used by video files per unit time, also known as code rate, which is the most important part of image quality control in video coding. At the same resolution, the larger the bit stream of a video file, the smaller the compression ratio and the better the picture quality.
