hyperdeck uncompressed
on Feb 22, 2013 at 6:38:17 am

I have a Panasonic AG-AF100. It outputs 8-bit out of it's sdi output. I wanted to know if anyone knows how much bit rate will I get from connecting it to a hyperdeck shuttle 2 and record uncompressed QuickTime?

Ofer,
I have some files at home from a BMD Hyperdeck studio,
recorded in SD uncompressed, I am at work right now.
In doing a export of a 1080p uncompressed 8 bit 422 file, both Mediainfo and the quicktime player report around a gig a second.

Here is a chart from a HDV forum,

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.

Of course Your milege may vary....
Perhaps record in the Avid DnxHD codec, gets you about five times the space as opposed to uncompressed.

Cheers,
Paul Lewis
