prThe 1080p format in the H.264 standard is the closest to the original image quality. It is a display format that reaches a resolution of 1920×1080 under progressive scanning. The resolution of most large-screen smartphones, TVs, and computer monitors adopts the 1920*1080 full HD standard. The higher the precision, the clearer the video.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer, Adobe Premiere Pro 2020 version.
H.264, also the tenth part of MPEG-4, is a joint video group (JVT) composed of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). , Joint Video Team) highly compressed digital video codec standard. The standard is often referred to as H.264/AVC (or AVC/H.264 or H.264/MPEG-4 AVC or MPEG-4/H.264 AVC) to name its two developers.
The main parts of the H264 standard include Access Unit delimiter (access unit delimiter), SEI (additional enhanced information), primary coded picture (basic image coding), and Redundant Coded Picture (redundant image coding). There are also Instantaneous Decoding Refresh (IDR, instant decoding refresh), Hypothetical Reference Decoder (HRD, hypothetical reference decoder), and Hypothetical Stream Scheduler (HSS, hypothetical stream scheduler).
1080p is a video display format. The foreign letter P means Progressive scanning;
It is the highest level of high-definition digital TV formulated by the Society of Motion Picture and Television Engineers (SMPTE) The format standard, the effective display format is: 1920×1080.SMPTE. It divides the different digital high-definition signal digital TV scanning lines into 1080P, 1080I, and 720P (i means interlace, and p means progressive). It is a display format that reaches a resolution of 1920×1080 under progressive scanning. It is the perfect integration of digital TV and computer technology.
1080p is a video display format. The foreign letter P means progressive scan, which is different from the interlaced scan of 1080i. The number 1080 means that there are 1080 horizontal scan lines in the vertical direction. Usually the picture resolution of 1080p is 1920×1080.
The frame rate is usually 25, which can be expressed after p, such as 1080p25, which means that there are 25 images in one second. Common frame rates include 24, 30, 60, etc. HDMI does not necessarily have 1080p output. The picture does not have to support 1920×1080 to be considered 1080p output. As long as there are more than 1080 vertical scan lines, it can be called 1080p. There is no strict specification for horizontal pixels. Full HD is A standard that regulates vertical and horizontal scanning pixels. 1080p only regulates vertical pixels (equivalent to horizontal scanning lines).
