24-bit, 4K UHD @ 120 fps: 24 × 3840 × 2160 × 120 = 23.8 Gbit/s. 48-bit, DCI 4K @ 144 fps: 48 × 4096 × 2160 × 144 = 61.1 Gbit/s. The actual data rate may be higher because some transmission media for uncompressed video require defined blanking intervals, which effectively add unused pixels around the visible image.
Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [4] encoded using High-Efficiency Video Coding. [4]
The main advantage of recording video at the 4K standard is that fine spatial detail is resolved well. [146] Individual still frames extracted from 3840×2160-pixel video footage can act as 8.3 megapixel still photographs, while only 2.1 megapixels at 1080p and 0.9 megapixels at 720p.
On September 5, 2014, the Blu-ray Disc Association announced that the 4K Blu-ray Disc specification would support HEVC-encoded 4K video at 60 fps, the Rec. 2020 color space, high dynamic range (PQ and HLG), and 10-bit color depth. [87] [88] 4K Blu-ray Discs have a data rate of at least 50 Mbit/s and disc capacity up to 100 GB.
[80] [81] Video output can be DCI 4K (4096 × 2160), 4K Ultra HD, 1080p, and 720p at frame rates of up to 60 fps with a color depth of up to 12 bpc with 4:2:2 chroma subsampling. [80] Audio output can be up to 7.1 channels. [80] Content is distributed online using the ODEMAX video service. [80]
Previous HDMI versions use three data channels (each operating at up to 6.0 Gbit/s in HDMI 2.0, or up to 3.4 Gbit/s in HDMI 1.4), with an additional channel for the TMDS clock signal, which runs at a fraction of the data channel speed (one tenth the speed, or up to 340 MHz, for signaling rates up to 3.4 Gbit/s; one fortieth the speed, or up to ...
The HEVC standard defines thirteen levels. [1] [2] A level is a set of constraints for a bitstream.[1] [2] For levels below level 4 only the Main tier is allowed.[1] [2] A decoder that conforms to a given tier/level is required to be capable of decoding all bitstreams that are encoded for that tier/level and for all lower tiers/levels.
The data rate for the M-JPEG files created can be up to 74 Mbit/s. In August 2016, Canon announced that the 5D Mark IV camera would record 4K video in M-JPEG, [6] with a data rate of approximately 500 Mbit/s. [7] A video that was recorded on a Canon 5D mark IV in DCI 4K using motion jpeg
