Ive been trying to insert transitions into a movie dropping it between slides. The transition time drops to 1 second and when increasing it to 1.5 or 2 and replaying it it either doesnt work, especially page roll or peel or similar and the only thing that does work is pulling a transition manually between each page. The transitions is black fade out and in, but works well.

  Why dont the others work?

Hi Pete, if you want to apply a "page peel" transition you have to expand the "Main" transition in the Library by clicking the double arrows and then drag and drop between the clips in timeline one of the sub-transitions.

If you drag and drop the "main" transition it doesn't work. Have a look at this screen rec: https://www.dropbox.com/s/e5rv6ioijzyir51/Page_Peel.wmv?dl=0
