Green & magenta highlight fringe - why?

[Karl Roeder]

I have attached two stills captured from RedCine. I am concerned with the colored edging along the highlighted woman's cheek. Image one shows a green fringe. Image two (one second later) shows a magenta fringe. Has anyone seen this before? All current release builds were used.

Yes.

Looks like high contrast edge CA. What lens were you using and at what aperture?

Color Space ?
Gamma Space ?

Thanks Jeff... We used a Zeiss super speed 50mm at ƒ 2.0, clean no filters.
Why do you think it would shift from green to magenta?

This looks like lens CA to me, which is not surprising on the Zeiss.

[Miltos Pilalitos]

This is almost certainly lens CA.

Yes, i have seen it many times before. Most recently on a shot i had last week which was shot with Zeiss lenses too.

responding to flameop's questions:

Rec 709 color space
Redspace gamma

Yes, it is chromatic aberration from the Super Speed lens not the camera. I've used a few different sets and there was always CA present to a greater or lesser degree- more so the wider the aperture.

Thanks for the responses everyone...
Any suggestions on the best primes available to minimize this (at wide apertures)? Cookes?

I have CA problems with still images on my Canon 1Ds MkIII all the time. The Adobe RAW processor has tools that can often remove the purple/green or red/blue fringe. Although not always.

No tools for Red that will remove CA fringe?
