Smooth flickering effect

Post by mnstudio » Sat Apr 07, 2012 3:26 pm

I'm using NV on various noisy clips. I find NV great! But I noticed that when I see the clip in pause mode, the filtering is astonishignly perfect. Playing the clip the filtering is still very nice, but you can see a little smooth flickering effect (which I think is the result of the filtering of the original noisy situation). Where can I act to adjust this parameter so to make it more or less evident, if I can?

It is not easy to advise without directly seeing the problem, but perhaps increasing the temporal filter radius might help..

Yeaahh. Increasing the temporal filter radius helps so much.... Good job!!!
And an other question: how could influence the result the Temporal filter threshold? To say it poorly... which are the effects increasing or decreasing the threshold?

The Temporal filter threshold setting determines how sensitive the filter is to changes (for example, motion of objects) in consequent frames. Higher values of this setting lead to more aggressive filtration with less attention to temporal changes (lower motion sensitivity). Lower values lead to less aggressive filtration with more attention to temporal changes and better preservation of moving details (higher motion sensitivity).
