Hi Cal,
I use a JVC GY-HD200U, and I record to a Datavideo DN-60 CF card recorder. That way it’s a HDV quality with a file based workflow. And no drop outs to worry about. Just make sure the firewire port works on the cam you purchase. You can find DN-60’s on ebay for around $500.

Cheers,

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.

Hi Dan,
Get a program like Mediainfo,
you can compare the files recorded
in the Hyperdeck with the Avid DNxHD codec,
and those rendered out of FCP.
You should be able to see what specs are
different.

February 29, 2012 at 3:41 am in reply to: HyperDeck as instant replay?

Just chatted with Chris, who ran the BMD Hyperdeck studio on our truck for a basketball game,
He said it seemed to run at whatever playback rate the DNF slow motion controller called for,
so you could start from a dead still frame and ramp it up to full playback speed,
I know on the built in control panel there is a way to make a clip loop,
but I don’t know if you can get it to run a clip at a variable rate, except by using a external controller. so 70%? maybe!
if you have a rs-422 controller that does variable playback.
Maybe in future firmware upgrades it will learn more tricks!

I will talk to the Replay Operator that ran it in our truck, it was loaned to us by another company, so I don’t have it anymore.

We tried a Hyperdeck Studio that was loaned to us, in our truck.
Using a DNF 300 slo-mo controller, it worked okay except for a couple of quirks. When recording, the DNF stop button doesn’t stop it, you have to use the Hyperdeck’s stop button, also there was frame interlace jitter when paused, doing 601 NTSC [SD-SDI]. Now this is with the factory firmware, and recording in uncompressed 10bit QuickTime. Also you need a Mac with a SATA drive dock, to format and erase the SSD.
Things may change with firmware updates.

Avid Newscutter or Media Composer

Hi Tedd,
I have a JVC GY-HD200, I am using a Datavideo DN-60, runs around $580.
It records to a Compact Flash card, using the firewire interface.
I can double master to both the DN-60 and tape,
so far haven’t needed the tape, the files work fine with Avid Media Composer.
Since you have a 250, you can use a recorder that uses the HD-SDI out,
like the Blackmagic Design Hyperdeck Shuttle, just under $400, plus you
need to get a suitable SSD drive.
The Atomos Samuri has it’s own video screen, it’s $1,600.
File based acquisition is so much better!

Cheers,
Paul Lewis
