In '''kdenlive''' a transition is a wipe or dissolve composition between two overlapping clips.
=== 如何加上一個轉場 ===
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.
<div class="mw-translate-fuzzy">
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.

To add a transition, adjust clips in the timeline so that the end of one overlaps the beginning of another.
Then right-click in the timeline at the overlap point, select <menuchoice>Add Transition</menuchoice> , then choose one of the transitions from the flyout.
In kdenlive version 15.12 the effect stack is merged with the "Transition" Tab to create a "Properties" window/tab.

The Properties window displays the settings for the effects on the currently selected clip (Figure 1) or the settings for the currently selected transition (Figure 2) depending on whether it is a clip or a transition that is currently selected.

<div class="clearfix"></div>
If you select the transition in the timeline [[File:Transition on timeline.png]] its properties will appear in the '''Properties''' tab (Figure 2).
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 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 Reverse check box in the Properties tab.
Mix Clips provides a way to add a transition between clips on the same track. To use it:
<div class="mw-translate-fuzzy">
# 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.
=== 轉場 頁籤 ===
# Select either clip. If there are clips in both ends of the one selected, the transition will be added nearest the playhead.
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.
<div class="mw-translate-fuzzy">
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.
In Version 17.04 you hover the mouse over the lower grey rectangle that appears at the end of the clips on the timeline and a tool tip will appear saying "Click to add Transition". If you click a dissolve transition will be automatically added.
* 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.
Older Versions:
{{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.}}
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.

This is the legacy way of doing transitions in '''kdenlive'''.
[[File:Kdenlive_transitions_legacy_god.png|frame|left|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.]]
Transitions will be created with the Automatic transition property set to true by default if the [[Special:myLanguage/Kdenlive/Manual/Timeline/Editing#Automatic_Transitions|Automatic Transitions Button]] is active.
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.

* 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.

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:
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.
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,
Adjust your clips so that they overlap.

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).
