Title: Strange colors on the topmost 6 lines in CinemaDNG from Chronos 2.1
Post by: clkdiv on May 26, 2020, 12:57:34 PM

Hello,

I have strange color shifts (or so) at the first 6 top lines of my frames coming out of my Chronos 2.1, see attached sample.

Not all of the shots of today have that issue, but some do. Any idea what this might be?

Thanks! Martin

I just know about that Line, which apears sometimes in the Center of the Height of the Image sometimes, which has to do with exposure time, might something like that?Looks like this to me, but i am no expert in sensor/ Software Artifacts at all...

Well, I don't think it's the marker line in cyan (or so), that was visible in former releases. However, I'd like to get rid of it. I'll test again tomorrow, maybe I can find out when it appears and when not.

would be interresting to see if it changes with different Framerates / Exposure times if reliably reproduceable.

Did you do a black calibration since the last change of either resolution, framerate or exposure time?
