Stebs Schinnerer Posted June 5, 2019 Share Posted June 5, 2019 Hello there! My name is Stebs and I'm new to these forums. Happy to be here, but not excited about my reason for joining. Hoping someone can shed some light on what's going on here... I recently shot a bunch of footage on my Alexa Mini and about halfway through shooting I was reviewing footage and noticed there seems to be yellow banding inside of the lighter colors. This has nothing to do with florescent lighting, however it almost looks like that at times. It appears as though it's affected inside shaded areas/gradients. My hope is this is something that is only affected inside the Arri 709 LUT I'm editing in but really cant tell. Here are a few still frames to show what I'm talking about: https://drive.google.com/open?id=1NWN4B9Y2PLEgBn9LOtOH4xqolvqvA0HC (full frame)https://drive.google.com/open?id=1Qd6slhaVx-y-WTckMfSCSuZywr7y_Zbi (200% zoom)https://drive.google.com/open?id=16yVH4Flh_cx-7SetWo6KzWQDH6p74zuO (400% zoom)https://drive.google.com/open?id=1FZUPfa4455hSO26PQxDGHLqwrw7mnhBX Here are the specs I shot in: ProRes 444 3.2k Arri RAW with Arri 709 LUT Sigma FF Cine Lenses Any thoughts would be greatly appreciated! Cheers, Stebs Link to comment Share on other sites More sharing options...

Bryan Fowler Posted June 9, 2019 Share Posted June 9, 2019 Is this a screenshot from Premiere? Or is it a exported still? Link to comment Share on other sites More sharing options...

Bryan Fowler Posted June 9, 2019 Share Posted June 9, 2019 Try exporting a clip, or frame. Is it still there? Premiere does dumb stuff to the color and gamma. Link to comment Share on other sites More sharing options...

Premiere does dumb stuff to the color and gamma. There is still yellowing inside the whites when I export, yes: https://drive.google.com/open?id=1RXWN2wXB5iSpJk9eDby8vaHq20b9fmBE However, the craziest thing was happening when setting the export settings... in the preview window in the export dialogue window the yellowing was there, but when I changed any setting (quality precent, image type, etc) the yellowing disappeared but then quickly came back. As though it was flickering on and off. I'm completely baffled. Link to comment Share on other sites More sharing options...
Bryan Fowler Posted June 9, 2019 Share Posted June 9, 2019 I'd try opening a clip in resolve, or FCPX or something else. see if it's a Premiere thing, or in the clip. (maybe you did that already) But it's not something I remember seeing personally. Link to comment Share on other sites More sharing options...

(maybe you did that already) But it's not something I remember seeing personally. Will try that out, I just dont have any of those programs. Planning to send over to a friend to see what they can do with it in Resolve. Fingers crossed and thanks for the feedback! Link to comment Share on other sites More sharing options...
Sander van de kerkhof Posted June 20, 2019 Share Posted June 20, 2019 see this allot when when I get the first edit made by someone in premiere. when the final edit is graded in proper software like resolve its gone so definitely something premiere does with the standard 709 lut.
