    Nitris DX headphones out: audio interference in going through HD material

    anyone else hearing this???

    When I go through my HD timeline in Full Quality Video or 10-bit Full Quality, without audio scrubbing, just passing over..

    ...I can hear interference for every frame that you move

    a faint tk tk tk tk    tk  tk

     

    This is not the case in Draft Quality or Best Performance Quality,
    And not hearing it on the monitor TRS out nor XLR out, ...

     

    let m know if you hear that too!

    Apparently this is ONLY the case with DNxHD footage!!

    -1:1 HD
    -DVCproHD
    -XDCAM HD
    -all SD

    don't have this audio interference when going through the images...

    anyone tried the headphone out? DNxHD material, full quality video?

    maybe it is just because it is unbalanced audio...

    ok, found something out!

    The HD project has to be in the Color Space: YCbCr 709 to hear the interference on DNxHD material!
    I just tried switching the project to RGB 709 and the audio interference was gone...

    So another call:

    FOR ALL YOU NITRIS DX box OWNERS: would you try out a thing for me:

    Connect a good headphone to the headphones out on your Nitris DX box (not even necesarry to turn the Volume Open!)

    -open a HD project, whatever flavor of HD, whatever raster type
    -make sure it is in YCbCR 709 Color Space
    -import or open a DNxHD file (whatever resolution)
    -put your Video Quality to: Full Quality Video(green) or 10-bit Full Quality (green 10)
    -go over the DNxHD material


    Can you hear audio interference for every frame you move??
    Please post your findings here!!

     

    thanks

    I just tried this test per your instructions using a set of AKG 240 headphones and I don't hear any interference out of the DX with a DNxHD 220 sequence. I'm on a Mac running v 5.03
