    I've solved the problem by installing KDE.runtime on Ubuntu 15:10 Wily Werewolf .
    Note: my Kdenlive is at version 15.12.0 .
    Another suggestion along with a rectangle type tool to select the part you want to zoom in would be useful and more facíl.
    Poderiam also add a tool callouts , such as arrows, circles ... etcs type callouts .
