Thanks for your answer, Steve… but it didn’t work.
There is little to do in this effect, so I can’t say it doesn’t work because I don’t know how to use it. I changed all that I could, I defined the 3 points (black, center, white) easily, since it’s a black and white video… Stabilizing the curves, it’s worse, and stabilizing the luminosity or the levels, I can’t see any difference.
Maybe it’s because the variations of luminosity are too high.
Or maybe there is another solution ? 🙂
Thanks for your ideas.
