For some noisy vids denoise 100% is to low, then I had to do a second denoise run. Some worse vids have a thick white veil (light source) over all and in order to get rid of this, the noise must be heavily reduced. I recomment to implement a activatable multiplier, so that the denoise slider has a double, triple… effect.
A contrast, gamma and color adjustment function (simple RGB ± would suffice) function is also on my wish list
