Transitions govern how '''Kdenlive''' cuts from one clip to the next. You can add many different transition effects using '''Kdenlive's''' transitions.
In '''kdenlive''' a transition is a wipe or dissolve composition between two overlapping clips.


=== How To Add a Transition === <!--T:3-->
<!--T:81-->
There are two ways of adding transitions in '''kdenlive''': '''Mix clips''', aka same tracks transitions, and the legacy way, which is transitions between clips on different tracks.


<!--T:4-->
<!--T:82-->
To add a transition, adjust clips in the timeline so that the end of one overlaps the beginning of another.
Wipes are greyscale images in .pgm (Portable GreyMap) format, and during the transition the composition track will be displayed in the darkest areas of the wipe image first. If the wipe is inversed, the composition track will become visible in the brightest areas of the wipe image first instead. You can download more wipes (by clicking the download button in the wipe composition properties) or create your own  and load them by clicking the folder button.

Mix Clips provides a way to add a transition between clips on the same track. To use it:

# Ensure that there is at least half a second worth of frames at the end of both clips (outside the timeline clip). Without that, kdenlive will not apply the transition, but display an error message.
# Select either clip. If there are clips in both ends of the one selected, the transition will be added nearest the playhead.

The transition length defaults to one second equally distributed between the two clips. You can drag either end of the transition to adjust.


<!--T:11-->
<!--T:91-->
You should preview your transition to make sure it is running in the direction you expect. For example, if it is a dissolve transition and it is running in the correct direction, then the first clip should cross dissolve into the second clip. But if it is in the wrong direction, the first clip will suddenly disappear (replaced by the second track). It will then fade back in and abruptly jump to second clip. If your transition is in the wrong direction, just select the <menuchoice>Reverse</menuchoice> check box in the '''Transition''' tab.
The default transition is dissolve, but you can select (click) the transtion and edit the wipe method and properties as desired in the effect/transition stack window.


=== How to create transitions with a single click === <!--T:23-->
<!--T:92-->
The composition method is set to Luma, and it does not make sense to change that, since there will not really be a transition. Other methods are meant for compositing two videos, not transitioning between them.


<!--T:24-->
<!--T:93-->
There is a shortcut for creating transitions between two tracks that overlap. If you hover the mouse over the overlapping region on the timeline, a green triangle will appear. Clicking this adds a dissolve transition between the tracks.
* Select the desired wipe from Wipe Method
* The Reverse option reverses the transtion.
* The Softness slider will affect the edges of wipe transtions.
* Set the desired duration
* Since 21.08: select the alignment of the transition, either left, centered (default) or right.

By default, new transitions are created as "Automatic Transitions". This means that if you adjust the overlap between the two clips involved in the transition, then the length of the transition will automatically adjust to cover the region where the clips overlap.


<!--T:14-->
<!--T:97-->
You can toggle off this feature on a transition by selecting the transition and choosing [[Special:myLanguage/Kdenlive/Manual/Clip_Menu#Automatic_Transition|Automatic Transition]] from the <menuchoice>Clip</menuchoice> menu. When Automatic Transition is off and you move a clip to change the overlapping region, then the length of the transition does not automatically adjust.
This is the legacy way of doing transitions in '''kdenlive'''.

Transitions

In kdenlive a transition is a wipe or dissolve composition between two overlapping clips.

There are two ways of adding transitions in kdenlive: Mix clips, aka same tracks transitions, and the legacy way, which is transitions between clips on different tracks.

Wipes are greyscale images in .pgm (Portable GreyMap) format, and during the transition the composition track will be displayed in the darkest areas of the wipe image first. If the wipe is inversed, the composition track will become visible in the brightest areas of the wipe image first instead. You can download more wipes (by clicking the download button in the wipe composition properties) or create your own and load them by clicking the folder button.

Mix Clips

Since 20.12

Kdenlive with mixed clips in the timeline. The toolbar button is circled with red, and the transition properties are on the right.


Mix Clips provides a way to add a transition between clips on the same track. To use it:

  1. Ensure that there is at least half a second worth of frames at the end of both clips (outside the timeline clip). Without that, kdenlive will not apply the transition, but display an error message.
  2. Select either clip. If there are clips in both ends of the one selected, the transition will be added nearest the playhead.

Ready to add the transition:

  • Keyboard: Press the U key.
  • Mouse: double-click at the point where the clips meet. This does not require a clip to be selected.
  • Toolbar: Press the Mix Clips button on the timeline toolbar

The transition length defaults to one second equally distributed between the two clips. You can drag either end of the transition to adjust.

The default transition is dissolve, but you can select (click) the transtion and edit the wipe method and properties as desired in the effect/transition stack window.

The composition method is set to Luma, and it does not make sense to change that, since there will not really be a transition. Other methods are meant for compositing two videos, not transitioning between them.

  • Select the desired wipe from Wipe Method
  • The Reverse option reverses the transtion.
  • The Softness slider will affect the edges of wipe transtions.
  • Set the desired duration
  • Since 21.08: select the alignment of the transition, either left, centered (default) or right.

To delete the transition, select it and press the delete key.

Tip
To apply only transitions on either the video or audio track just lock the track on which you don’t want a transition to be applied and add transitions by one of the above ways on the other track.


Transitions between clips on different tracks

This is the legacy way of doing transitions in kdenlive.

To the left the purple one-click circle to add a wipe composition. In the middle the composition bar, and on the right the properties.


To add a transition,

  1. Adjust your clips so that they overlap.
  2. hold the mouse wheel over the top clip bottom corner, and click the purple circle appearing (the status bar will say "Click to add a composition"), or alternatively right-click either clip and select Insert a composition | Wipe

The default transition is a dissolve, to change that select (click) the composition bar to show the effect/composition stack window.

The transition, when added this way, will cover the overlapping area between the clips.

You can:

  • Select a composition track. The default is "Automatic" which is likely the correct choice in this case.
  • Select a wipe.
  • Enable Inverse to inverse the wipe.
  • Enable Revert to revert the order of the videos in the transition (which you probably do not want).

If you move or adjust your clips after adding the transition, you need to refit it manually if desired. You can drag the entire transition with the select tool, and adjust its duration by dragging either end.
