sigmoidaltransfer This is the Frei0r.sigmoidaltransfer filter from Janne Liljeblad. Desaturates image and creates a particular look that could be called Stamp, Newspaper or Photocopy. Two parameters: Brightness: Controls Brightness of image. Range 0 to 1 Sharpness: Controls sharpness of transfer Range 0 to 1 Both parameters default to 0 in Kdenlive - which is unfortunate because this results in a totally black frame. You need to have numbers above zero to see the effect. This effect appears to have arrived with version 0.9.5 of Kdenlive Retrieved from "https://userbase.kde.org/index.php?title=Kdenlive/Manual/Effects/Misc/sigmoidaltransfer&oldid=297775" This page was last edited on 10 March 2013, at 15:32.
