Uncompressed video is digital video information that has not been compressed, or was not processed with compression on it when the video was captured directly from a camera. It has variable data transfer rates. Native digital video capture rates are roughly 30Mbits/s.
Storage and Data Rates for Uncompressed Video
The storage and data rates for uncompressed video are listed below:
525 NTSC uncompressed
8 bit @ 720 x 486 @ 29.97fps = 20 MB per/sec, or 70 GB per/hr.
10 bit @ 720 x 486 @ 29.97fps = 27 MB per/sec, or 94 GB per/hr.
625 PAL uncompressed
8 bit @ 720 x 576 @ 25fps = 20 MB per/sec, or 70 GB per/hr.
10 bit @ 720 x 576 @ 25fps = 26 MB per/sec, or 93 GB per/hr.
720p HDTV uncompressed
8 bit @ 1280 x 720 @ 59.94field = 105 MB per/sec, or 370 GB per/hr.
10 bit @ 1280 x 720 @ 59.94field = 140 MB per/sec, or 494 GB per/hr.
