Color Preview Problem in Speedgrade

Aug 9, 2012 3:47 AM

Tags: #color #preview #speedgrade

Hello,

 

I work with Speedgrade in TGA sequence.

I note different colors in TGA preview on my computer (Mac preview) and in Speedgrade preview. Image is more yellow.

When I try an export in TGA too, exported colors are same as before import.

So I think Speedgrade preview is not right.

 

(I keep TGA linear curve in display option)

 

 

I tried H.264 import too and there are catastrophic colors (everything is red).

 

Is there a solution ?

    Speedgrade CS6 is not color managed by the OS.  Most likely Preview is color managed in OS X,  this will lead to a discrepancy between what you are seeing, and how your monitor is profiled.

     

    Have you used a hardware calibrator, or the Mac OS X color management calibration software Utility?  This would explain why you are seeing two different things.

     

    If so, the solution is to remove your monitor profile from the color management, or attempt to built a LUT from your .ICM profile of your monitor.  I've used DispcalGUI to convert a monitor .ICM into the proper LUT for the color space I wanted to work in (REC.709)

    . i have the same problem with speed grade ...i have imported canon 5d footage with cinestyle picture style...in osx preview or quicktime looks like in camera very flat but after import in speed grade it looks like standard picture style ...i tried to calibrate with default color profile from my macbook pro (after conversion from icc/icm to cube file with DispcalGUI as Alex Meija..described here ) but nothing happen when i select the cube profile in calibration..i think this is a bug inside Speed Grade i can't use it...i m back to colorista ii in AE..

    the single profile in calibration that looks nearly like original footage is when i select gamma 1.8 but is not ok

    I thank you for replies.

     

    Finally I think Speedgrade preview may not be bad. Quick time preview for example make bad colors (black is not black)

     

    So I continued like that.

     

    Thank you
