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.

Currently uncompressed video is supported by several Nikon DSLRs with the Expeed 3 image/video processor and professional cameras like Arri Alexa.

Pixel Encodings and Color Depth
There are three different pixel encodings that may be sent across an HDMI cable: YCBCR 4:4:4, YCBCR 4:2:2 and RGB 4:4:4.
There are four color depths supported: 24-, 30-, 36- and 48-bits per pixel.

Storage and Data Rates for Uncompressed Video

Formula: Uncompressed data rate = color depths * vertical resolution * horizontal resolution * refresh frequency

Examples

24bit @ 1080i @ 30fps :24*1920*1080*30=1.39 Gbps.
24bit @ 1080p @ 60fps :24*1920*1080*60=2.78 Gbps.

The storage and Data signaling 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.

1080i and 1080p HDTV uncompressed

8 bit @ 1920 x 1080 @ 24fps = 95 MB per/sec, or 334 GB per/hr.
10 bit @ 1920 x 1080 @ 24fps = 127 MB per/sec, or 445 GB per/hr.

8 bit @ 1920 x 1080 @ 25fps = 99 MB per/sec, or 348 GB per/hr.
10 bit @ 1920 x 1080 @ 25fps = 132 MB per/sec, or 463 GB per/hr.

8 bit @ 1920 x 1080 @ 29.97fps = 119 MB per/sec, or 417 GB per/hr.
10 bit @ 1920 x 1080 @ 29.97fps = 158 MB per/sec, or 556 GB per/hr.

1080i and 1080p HDTV RGB (4:4:4) uncompressed

10 bit @ 1280 x 720p @ 60fps = 211 MB per/sec, or 742 GB per/hr.
10 bit @ 1920 x 1080 @ 24fps = 190 MB per/sec, or 667 GB per/hr.
10 bit @ 1920 x 1080 @ 50i = 198 MB per/sec, or 695 GB per/hr.
10 bit @ 1920 x 1080 @ 60i = 237 MB per/sec, or 834 GB per/hr.
