Si potrà quindi modificare il comportamento della transizione con un doppio click del pulsante del mouse sopra il rettangolo giallo. Questo muterà il suo colore da giallo a rosso e farà comparire la scheda "Transizione" nel pannello in alto a sinistra, dove si potranno regolare le proprietà del tipo di transizione applicata --- se si desidera si potrà scegliere un altro tipo di transizione selezionando una delle icone sulla parte sinistra della scheda. Chiameremo questa operazione "entrare in modo modifica" della transizione.
'''Transitions''' are probably one of the most interesting features of non-linear video edition. They are used between two clips and they allow a soft, or a sophisticated way of passing from one scene to the other. This is a contrast with the "hard" or "dry" cut between scenes -- which, prior to the computer adoption, were very hard to make or required special equipment.
For using a transition effect in Kdenlive, you must place the two clips you want to join in different video tracks, in such a way that they "overlap" each other a little bit --- exactly in the points you want to place the transition. Then, right-click the mouse over the first clip (the "outgoing" one), then select '''Add transition''' in the context menu, and point the mouse towards the arrow for seeing the transition types available. Then you will see a yellow rectangle placed between the video tracks, representing the transition. For having a live preview of how the transition will look like, simply drag the timeline cursor from left to right over the transition area.
You can modify the transition effect, or the way it works, by left-clicking the mouse twice over this yellow rectangle. This will turn it into red and cause the "Transition" tab in the top-left panel to pop and show the properties you can set for the currently selected transition effect --- and, if you want, you can choose another type of transition, clicking at the icons at the left of this panel. We will call this operation as "entering in edit mode" for the transition.
At the time of version 0.4, Kdenlive provides four major kinds of transitions, which are expected to be expanded and more stable in version 0.5.
= Crossfade =
This is the most known and used transition effect --- the scenes are softly blended, the second scene becoming bolder until the first scene is completely over. This effect can also be used for the widely known '''fade-in/fade-out''' effect.
For creating the fade in/out, you can create a [[color clip]] with any desired color and use it as the first or second scene of the transition. If you simply want to use the default "fade to/from black", you can simply enter in edit mode and, at the top-left panel, click in the combobox ''Perform transition with:'' and choose "Background track (black)".
