Their new location using the motion vector data.

The decoder will move the macro blocks, which have already been transmitted, to Motion Compensations allows the encoder to transmit motion vector information about the macro blocks that move but which have the same pixel level information.

In a B or P frame, only moved or changed macro blocks are transmitted. The longer the GOP length, the fewer I frames will be present in the stream, naturally the lower the bitrate. The number of frames from one I frame to the next I frame is referred to as the GOV length, which can be modified for the video stream. I frame, B frame and P frameĪn I frame followed by a series of P and B frames is referred to as a Group Of Pictures or GOP. The frames with changes are referred to as P or B frames. To be specific, H.264 compression going a process of inter and intra prediction, motion compensation, and deblocking fliter.Ī video stream is composed of a reference frame called an I frame, and then changing areas of the image are transmitted and overlaid on the origin reference frame to create the current image of the scene. H.264 follows the regular process of video compression standard, namely estimation, transformation, quantization, deblocking, and entropy coding, as well as achieves technical innovations in some parts. To make PC, Mac support H.264 video or create H.264 videos, free download H.264 (MPEG-4 AVC) Codec/encoder on Windows 10 or macOS. H.264(MPEG-4 AVC) codec is supported by GPU hardware accleration using Intel Quick Sync Video.H.264(MPEG-4 AVC) codecis able to support high resolutions like 4K and even 8K videos.H.264 codec is widely used in applications, networks, streaming formats like HTML 5, Apple HLS, and camcorders.That means H.264 delivers High-def quality with half even quarter of Bit-rate usage. H.264 codec can encode H.264 videos with approximately 3 times fewer bits than MPEG-2 (the DVD standard). H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a standard for video compression.
