It includes the recording or cassette formats DV, MiniDV, HDV , DVCAM, DVCPro, DVCPro50, DVCProHD, Digital8 , and Digital-S .
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.
