Re: SSD recording with Blackmagic hyperdeck

Avid DNxHD compression is about 1/6 of uncompressed.
But is called lossless because it is so close to uncompressed in picture quality.
Many cameras have recording in higher ratios of onboard compression with lower quality.
That is what the Shuttle is for, higher quality with lower(or no) compression using HD SDI or HDMI output from the camera head.

Re: SSD recording with Blackmagic hyperdeck

Thanks Paul
Does that mean if we record in DNxHD we can have 6x longer for the same space that to record in uncompressed? and how to do that with Shuttle deck 2?

Re: SSD recording with Blackmagic hyperdeck

Yes, 6x longer.
You need to use a software utility called Black Magic Hyperdeck Utility to change settings on the Shuttle 2 to the desired format, DNxHD, ProRes or Uncompressed.
You can also set record trigger to SDI timecode or SDI start/stop(or never).
This is done over a usb connection.

Re: SSD recording with Blackmagic hyperdeck

Wow great, how come I did see these modes with Utility 2. Will check it over again . Does the DNxHD give good compression with 4:2:2 color sampling?
Thanks Paul.

Yes.
10bit 4:2:2
It is termed a lossless codec because it is so close in quality to uncompressed.

Re: SSD recording with Blackmagic hyperdeck

Yeah the start/stop function doesn't work with my EX1 either. I tried to record DNxHD Quicktime (from 1080 sp) and my 240gbs SSD got full at 2hrs18minutes

Now I am trying it with DNxHD alone (From SD) to see if it can get any longer

Re: SSD recording with Blackmagic hyperdeck

2hrs 18 minutes is pretty good.
I think it is better to leave 20% or 15 minutes free on the ssd though.
I have encountered severe frame dropping on a HyperX 120Gb SSD when it was nearly full.
As an SSD fills up it gets to a point where the write speed decreases.

This kind of media is quite cheap when compared with Sony or Panasonic memory or even compact flash cards.
It is about the same as what I paid for DVCPro tapes many years ago.
And they're getting cheaper.
