Uncompressed video
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 recording devices (including general purpose computers), and in video processors that perform functions such as image resizing, image rotation and text and graphics overlay. It is conveyed over various types of baseband digital video interfaces, such as HDMI, DVI, DisplayPort and SDI.
Some HD video cameras output uncompressed video, whereas others compress the video using a lossy compression method such as MPEG or H.264. In the compression process, some of the video information is removed, which reduces the quality of the video when decompressed. When editing video, it is preferred to work with video that has never been compressed as this maintains the best possible quality, with compression performed after completion of editing.〔(Using Uncompressed Audio and Video Streams ) Microsoft〕
==Characteristics==
The lossless video has no compression artifacts.
Currently there is no standardized lossless video file format except for HDMI, which uses the YCbCr and RGB formats listed below. This makes it necessary to store it best with a related description file about the used resolution and video mode. These files can be combined with lossless compression with the use of file archivers.
