Frage von Britta Leuchner:
Hallöle,
Has anyone of you some work-arounds to the often long-run "flicker" picture-in areas, where they had strong color correction via HSV-Key perform mask? I already have with Blurs and Glows, and smoothed contrast, the alpha mask from the HSV-Key output until it stops. But there already appears before a flickering in the original image s.der HSV limit being what it was not visible. Without violation of other areas in the field would be a Key HSV-HSV-Key adjustment is not possible. So I hope for an idea that is more placed behind the Key.
I hope to make the color ranges Möglichlkeiten "slow", so watch the a A - B - A Farbflackern only A is.
I work in the fall with Nuke. Someone 'ne Idee? Or alternative approaches. Würde mich sehr freuen. Seh grad the forest for the trees anymore.
A thousand thanks in advance, and nice greeting
Antwort von tommyb:
A denoising on a temporary basis (ie) over multiple frames of time should help.
In this example, individual pixels of the images with Picture X X-2, X-1 and X +1 and X +2 (thus comparing two predecessors and two successors).
If the difference is only marginal, the pixels are aligned, and it no longer flickers. If the difference is very large, a change in the area) was adopted (cutting, pivoting, and it is not aligned.
This Threshold should not set too high, because that would lead to formation of ghosts.
The main question: can nuke it?

The main question: can nuke it? ojee ... sounds to me like advanced python or tcl scripting ... whether it can nuke, the question arises not because nuke is an open framework. The question is: can I program the ... * lump in my throat, swallow **
But tell me, single pixel noise reduction, which smooths out yet more grain or noise, right? flicker would be a flat but rather by a flächenbegrenztes X-2, X-1 - X - X +1, X +2 überbrücked, right? dear, then I moved edges war, when the face moves, right?
