Uncompressed video is digital video that either has never been compressed or was generated by decompressing previously compressed digital video. It is commonly used by video cameras, video monitors, video recording devices (including general-purpose computers), and in video processors that perform functions such as image resizing, image rotation, deinterlacing, and text and graphics overlay.
The main advantage of recording video at the 4K standard is that fine spatial detail is resolved well. [147] 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.
XAVC can use level 5.2 of H.264/MPEG-4 AVC, which when XAVC was introduced was the highest level supported by H.264 and which they now call XAVC S 4K/XAVC S HD.In addition their XAVC HS 4K or 8K versions can use MPEG-H HEVC/H.265 codec with 10-bit color sampling.
Many of these resolutions are also used for video files that are not broadcast. These may also use other aspect ratios by cropping otherwise black bars at the top and bottom which result from cinema aspect ratios greater than 16∶9, such as 1.85 or 2.35 through 2.40 (dubbed "Cinemascope", "21∶9" etc.), while the standard horizontal ...
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.
Extended Display Identification Data (EDID) and Enhanced EDID (E-EDID) are metadata formats for display devices to describe their capabilities to a video source (e.g., graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).
DNxHR HQX - High Quality (12-bit 4:2:2) (UHD/4K Broadcast-quality delivery) DNxHR 444 - Finishing Quality (12-bit 4:4:4) (Cinema-quality delivery) Bandwidth requirements for the codec and its different flavors have been announced in the "Avid High Resolution Workflows Guide - December 2014" on page 166-172.
This is the highest resolution that generally can be displayed on analog computer monitors (most CRTs), and the highest resolution that most analogue video cards and other display transmission hardware (cables, switch boxes, signal boosters) are rated for (at 60 Hz refresh). 24-bit colour requires 9 MB of video memory (and transmission ...
