I installed kdenlive from the respective ubuntu repository for the upcoming ubuntu 14.04 trusty daily build. In the effect list, the "alpha operations" effect, which I use often, is missing (and it seems that so are several others too). I looked in the kde4>applications>kdenlive>effects folder, where I saw that the respective xml-file for "alphaops" was present, yet it doesn't show on the kdenlive user interface. What can I do?
