    Upcoming 4:4:4 Recorders
    #1
    Default
    With the release of 4:4:4 output-capable cameras (F3 & FS100 to name two), some companies have announced upcoming 4:4:4 recorders.

    The ones I know of are:

    - Cinedeck Extreme (http://www.cinedeck.com/content/#/?type=serial)
    - Gemini 4:4:4 (http://blog.abelcine.com/2011/03/21/...-444-recorder/)
    - Cinemartin SFV (http://cinemartin.com/)

    The Cinedeck is a crazy $10K I think, while the other two are about half of that. And they all need HD-SDI for 4:4:4, which means one would need an HDMI-to-HD-SDI adaptor (like from AJA or BlackMagic) with the FS100, right?

    Edit: Cinedeck Extreme accepts HDMI in.

    What other upcoming 4:4:4 recorders are there out there?

    Wouldn't work. HD-SDI can't do 4:4:4. It takes two SDI channels to carry that much data. So you'd need a new product that converts HDMI to dual-link HD-SDI or to 3G-SDI.

    Like this one? http://www.gefen.com/kvm/dproduct.jsp?prod_id=9397


    Edit: According to Wikipedia, the HD-SDI bandwidth is ~1.5 Gbit/s. In this DV info interview Convergent Design say that uncompressed data is typically around 125-150 Mbyte/s, which is 1000-1200 Mbit/s. Wouldn't one HD-SDI be enough for the FS100's 8-bit 444?

    SDI isn't 8-bit, it is always 10 bit. There is no space savings for 8 bit. And there is no provision for 4:4:4 in the SDI spec. It isn't just a raw data pipe like a USB cable.

    That Gefen unit might do it. It doesn't mention 4:4:4 anywhere but if it accepts RGB input then it might work. It won't output 3GSDI at 4:4:4 though, only dual link.

    Sure, but still. "Uncompressed data is typically around 125-150 Mbytes/s". Isn't that within the HD-SDI specs?

    The CineDeck Extreme is $8500 and the Gemini is $6000. Not that huge a difference.

    Manny moons ago Cineform was planning to make a Cineform based recorder.

    Somehow David decided to ditch the project. Thatīs a real shame, cause it would now now (several years later)
    be probably selling like hot cake.

    By the way. The Matrox MXO2 LE can capture 10-bit uncompressed RGB via HDMI.

    Many people already have MacBook Pro's with Thunderbolt. When Matrox releases their updated MXO2 line with Thunderbolt I/O, the MXO2 LE could serve as a "cheap" ~$1000 4:4:4 recorder (presuming you already have the computer.)

    Not a great solution for ENG, but perhaps for narrative work where only the length of the HDMI cable would limit the range of camera movement.

    Im confused as to where Thunderbolt comes in to the picture... from what I can read its only supported by ExpressCard/34, and only the 17" has an express card slot.

    Would have been nice to use it on the 15" as well.
