  • Gamma shift while capturing dual link in ProRes 444

    Posted by Arthur Puig on July 23, 2010 at 6:07 am

    I’m digitizing dual link in Prores 444, against single link in ProRes 444, and I can see that the dual link has the blacks at around 10 or so, whereas in single link is at 0.

    How can I fix that?

    Thanks!

    Ok
    You know the drill, machine specs, software and OS versions…
    Are you using an easy setup or did you modify an rgb setup.

    What is your original? A Log file often looks flat while that single link will be under Rec 709 ( check my blog for a log recording vs. a linear rec 709 of the same clip.

    Using Mac Pro octo, Kona 8.0 drivers and FCP 7.0.2, digitizing dual link in Prores 4444 from a HDCAM-SR, blacks are lifted. Blacks are OK when digitizing from HDCAM-SR in single link in ProRes 4444

    It is 7.5 not 10, and it is usually in the setup playback preferences of the HDCam deck

    [Fred Connors Jr.] “It is 7.5 not 10, and it is usually in the setup playback preferences of the HDCam deck”

    THERE IS NEVER “SETUP” IN DIGITAL FORMATS

    I stand corrected, Gary.

    There is the option the add setup to the composite out, I was mixing my outputs.
