    Hi Guys

    I can’t figure out why these blacks are different. I had to crop the logo in fcpx to lose some text around it, and the rectangle around the PS4 logo shows black on a ‘basic title’ which has no fade as far as I’m aware.

    The PS4 logo appears to be srgb.

    Any ideas aside from cutting the logo out in Pshop?

    Thanks

    HI Andy – that’s an insightful assumption, especially considering the attached image shows no difference whatsoever in the blacks! Sorry about that – there’s a noticeable difference on the image on my desktop but not on the uploaded version it seems.
    Either way I think the blend mode will fix it.
    Thank you.

    It’s the PS4 logo, isn’t it?

    It probably has to do with the nature of the graphic being created in a non video or print environment.

    Is this living online or going out to broadcast?

    I see the issue just fine on my iphone. What do your scopes say? A simple color adjustment on the lighter background should do the trick.

    BG is video black (16) I’m sure.

    It’s the logo that’s been CMYK or something at some point and got shoved down to superblack.

    Hi Guys
    Many thanks for your input.
    It’s living online.
    Yes it probably started life CMYK but isn’t now.
    Scopes read it as black.
    Colour adjustment helps.
    Thanks again.

    I put you JPEG in X and the waveform didn’t show super lack, but the histogram did. Odd.

    Yeah. I was going to check this. This seems buggy.

    That’s exactly what I found. Weird.

    I had something similar with a white graphic some years ago.

    Looked fine on the computer screen but when stuck to DVD the supplied graphic was in a grey box. Bit of playing with gamma and levels sorted that.

    When importing graphic files FCP X doesn’t give you the full dynamic range by default and instead scales it down to fit into 0-100 IRE – unless you stretch it back out.

    Compare these two screenshots of the same grayscale ramp imported as a TIFF from Shake. The first is the import as it comes in, the second is the same thing stretched out using the color board.

    This might explain why the blacks were sat up in this particular case.
