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 video 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. In the documentation of h.264 (also known as AVC or x.264), the recommended bitrate of H.264 video is as follows: Suggested bitrates for different video resolutions with H.H.264 Encoder for Mac OS X 10.6 or later Table of Contents Therefore, the bitrate does have its optimal value. Yet in the range of visual resolution, when the bit rate is high enough, it doesn't seem to make a difference. However, do videos with higher bitrate get high quality? In theory, it's true. To judge the advantages and disadvantages of a video coding-decoding technology, on one hand, we can compare which video's quality is better based on the same network on the other hand, we can compare which video occupies less room on the basis of the same quality. The way to solve the contradiction is video coding technology. Therefore, the high quality of video requires high network bandwidth. Normally, the video streaming occupying more bandwidth gets higher quality. In the application of video conference, the quality of video and the network bandwidth occupation are contradictory.

The Necessity of Setting Appropriates Video Bitrate

Video bitrate is the number of bits per second output from video data (video color quantity, brightness measurement, pixel quantity), and the usual unit of video bitrate is kbps. So what is an appropriate bitrate setting for H.264 encoding? Is it different when applying to videos in different resolutions? See the answers below. If you have the plan to encode or re-encode video into H.264 with, like say freeware HandBrake, one thing that you better pay close attention to is the bit rate settings, which, to some extent, decides your video visual quality. H.264 might be the most popular codec used to encoding HD videos, for its high compression ratio.
