Need a table for required bandwidth for various formats – HDCam, HDV, SDI, 10-bit 4:2:2 etc

[Ed Dooley]

This might get you started:
Ed

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 per/sec, or 742 GB per/hr.
10 bit @ 1920 x 1080 @ 24PsF = 190 per/sec, or 667 GB per/hr.
10 bit @ 1920 x 1080 @ 50i = 198 per/sec, or 695 GB per/hr.
10 bit @ 1920 x 1080 @ 60i = 237 per/sec, or 834 GB per/hr.

And this from HDforIndies:
HDV

Not really a professional format, but I’m sure some indies will use it.

HDV resolution 1:

Playback frame size: 1280×720
Acquisition frame size: 1280×720 to tape
frame rate/s: 30 fps progressive

no interlaced 720 signal, no 24p

bit depth & color space: 8 bit, 4:2:0 (alternates which color channel gets recorded)
datarate: 19MBit/sec (about 2.375 MB/sec)
compression type: MPEG-2 transport stream, with GOP (group of pictures) 15 (think of it as keyframes every 15 frames)

HDV resolution 2

playback frame size: 1920×1080
acquisition frame size: 1440×1080 to tape (but the Sony upsamples 960×1080 to this)
frame rate: 60i (interlaced, no progressive options)
bit depth and color space: 8 bit, 4:2:0
datarate: 25Mbits (about 3.125 MB/sec, slightly less than DV)
compression type: MPEG-2 transport stream, with GOP (group of pictures) 15 (think of it as keyframes every 15 frames)

DVCPRO HD:

1280×720 10 bit 4:2:2 at 59.94 or 60 progressive fps. 24, 25, 30 fps also possible as standard stuff, or anything from 4 to 60fps if the hardware or software frame rate converter is used.

1920×1080 10 bit 4:2:2 at 59.94 interlaced

Reality:

10 bit 1280×720 4:2:2 progressive off the HD-SDI tap gets sampled down to 8 bit 960×720 at 4:2:2 colorspace then compressed to about 5 1/2 MB/sec
10 bit 1920×1080 interlaced only off the HD-SDI tap (gets sampled down to 8 bit 1280×1080 at 4:2:2 colorspace then compressed to about 14 MB/sec

HDCAM

1920×1080 10 bit 4:2:2, progressive or interlaced, 24p possible (psf)

1920×1080 10 bit 4:2:2 off the HD-SDI gets sampled down to 1440×1080 8 bit at 3:1:1 colorspace then compressed to something like 22.5 MB/sec (don’t have hard #s)

HDCAM SR

1920×1080 10 bit 4:4:4, progressive or interlaced, 24p possible (psf)

Reality:

Hey, this one (finally) works well:

1920×1080 10 bit RGB 4:4:4 of the dual HD-SDI taps actually stays just that – 10 bit 1920×1080 RGB 4:4:4. It is then compressed with MPEG-4 SP (Studio Profile) with 4.27:1 compression, results in a 50 MB/sec datastream to tape. Uncompressed off the taps, that signal is about 180MB/sec for 24fps.

Panasonic D-5:

1920×1080 10 bit 4:2:2 progressive or interlaced to tape as I understand it. 1080p24 possible. The deck is $99,000. HDCAM SR seems like better quality, better deal.

Thanks Ed that’s all really useful. I guess that there’s not too much about HDV yet, which is the real thing that I wanted technical specs for, it’s a newish format I guess.

Really appreciate your help.

[Ed Dooley]

The 2 flavors of HDV, when compressed to tape are the same as DV as far as bandwidth, 19 and 25, depending on the flavor.
