Paul is correct.

 

Process all hardware real-time effects at 16 bit to avoid the color space difference.  HW RT effects are actually somewhere at 12 bit and cause the shift.  Going 16 bit on these effects (the rest can remain at 8 bit, no problem) will resolve the issue.

It's probably a bit depth or colourspace conversion problem, I get this when going from a rendered portion of a cc to a realtime version - thats why you don't see the problem when you're using the DVE to crop...

Set the bit depth to 16bit on the crop - does that remove it??

If you activate process alpha aswell as rgb in the process tab on the crop, that should fix the problem.

So I have a color correction on a clip.  When I add a crop as either a clip effect or track effect downstream from a color correction, the color changes.  It seems to add a mild green tint.  If I reverse the order so the crop is first then the color corrector second the color is fine but now I'm color correcting the crop which I don't want.

What is causing this color shift?  I suppose I could color correct around the shift (meaning balance the clip taking in account the shift) but this seams like a very un-pro work-around.  Any ideas?
