2K distributions can have a frame rate of either 24 or 48 FPS, while 4K distributions must have a frame rate of 24 FPS. [ 6 ] : §3.1.4.2 Some articles claim that the terms "2K" and "4K" were coined by DCI and refer exclusively to the 2K and 4K formats defined in the DCI standard. [ 8 ]
Advanced Video Coding (AVC), also referred to as H.264 or MPEG-4 Part 10, is a video compression standard based on block-oriented, motion-compensated coding. [2] It is by far the most commonly used format for the recording, compression, and distribution of video content, used by 91% of video industry developers as of September 2019.
One drawback of this resolution regarding encoding is that the number of lines is not an even multiple of 16, which is a common macroblock size for video codecs. Video frames encoded with 16 × 16 pixel macroblocks would be padded to 640 × 368 and the added pixels would be cropped away at playback. H.264 codecs have this padding and cropping ...
This transmission of 4K HEVC video in real-time was an industry-first. [87] On November 14, 2013, DivX developers released information on HEVC decoding performance using an Intel i7 CPU at 3.5 GHz which had 4 cores and 8 threads. [88] The DivX 10.1 Beta decoder was capable of 210.9 fps at 720p, 101.5 fps at 1080p, and 29.6 fps at 4K. [88]
Both are capable of recording video at 4K resolution, but can only do so at 30 fps whereas most competitors support 60 fps as well. In a tweet, Google stated that "We find that the majority of users stick with 1080p, so we focus our energy on improving our quality in this mode, versus enabling a 4k 60 fps mode that could use up to half a ...

GoPro, Sony and other action camera competitors record video at 1080p and 2.7k at 120 fps, 720p and 1080p at 240 fps, and 4k at 60 fps. Although the video formats were designed for slowing down in post-production, the cameras generally record very high frame rates [ 7 ] in high definition with generally clear audio.
Video bandwidth requirements are growing continuously, as video resolutions, frame rates, bit depths, and the amount of video streams are constantly increasing. Likewise, the capacities of video links and communication channels are also growing, yet at a slower pace than what is needed to address the huge video bandwidth growth.
