Transitions in KDEnlive
When you place one clip after another in the Timeline, the transition from one clip to another can sometimes be jarring:
KDEnlive addresses this by providing Transitions. Unlike Kino, different effects can be applied to each Transition. In order to apply a Transition, you need first to align the two clips in the Timeline, so they overlap:
Next, position your mouse pointer over the bottom right corner of the top clip - an animated green triangle should display:
If you left-click the green triangle, a Transition will be created covering the period the two tracks overlap (-although this can be stretched or compressed as required):
By default this is a Dissolve transition, but this can be changed to one of several different types by left-clicking the required Transition and picking the desired transition from the drop-down list in the "Transition" tab:
Finally, you can preview the effect of the Transition via the Project Monitor:
