轉場負責管理 '''Kdenlive'''裡,如何從這一片切換到下一片. 你可以加增很多不同的轉場,經由 '''Kdenlive's''' 轉場.
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.


加上轉場之前要考慮, 將兩段短片的重疊一小部分,上片的結尾和下片的開頭重疊。
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:


當你選定了時間軸上的轉場 [[File:Transition on timeline.png]] 它的屬性頁會出現在 '''轉場''' 頁籤。 (假如這個屬性頁看不到,請使用 <menuchoice>View -> Transitions</menuchoice> 來進入。)
# 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.

您須預覽一下轉場以確定它執行的方向是您所預期的。例如:假如您設定溶解(dissolve )轉場,然後執行的結果,正確方向應是第一段慢慢溶解後接到第二段。但是,當方向錯誤時,第一段將突然消失(被第二軌取代掉)。它會先消失掉而且突兀地掉到第二段。 假如您的轉場效果方向錯誤,只要選<menuchoice>Reverse</menuchoice> 勾選盒,在 '''Transition''' 頁籤.
* '''Keyboard:''' Press the <keycap>U</keycap> 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


=== 如果點一下來產生一個過場 ===
The transition length defaults to one second equally distributed between the two clips. You can drag either end of the transition to adjust.


產生兩個重疊一部分的短片軌之間的過場效果有一個簡便做法。假如你輕滑滑鼠到時間軸上的重疊區域,這時有一個綠三角會出現。點擊它,會在兩短片軌上放上一個消失(dissolve )過場。
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.


{{#evp:youtube|h1k7GbEssqA}}
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.


=== 自動化過場 ===
* 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.


一般而言,新過場都是經由 "Automatic Transitions"產生的。意謂著如果您調整兩重疊片段的轉場,那麼轉場效果的出現長度會自動延伸到含蓋重疊的區域。
To delete the transition, select it and press the delete key.


您可以把轉場裏的這個特性關閉。請點這個轉場並選擇 [[Special:myLanguage/Kdenlive/Manual/Clip_Menu#Automatic_Transition|Automatic Transition]] 源自於 <menuchoice>Clip</menuchoice> 選單。當自動轉場( Automatic transition )關閉,您移動其中一段短片,改變法重疊的區域,這時轉場的播放時間不會自動調整。

To add a transition,


Q: How to add a cross fading effect?
# Adjust your clips so that they overlap.
# 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 <menuchoice>Insert a composition | Wipe</menuchoice>


A: Make clips on two tracks overlap in time, then pull the green dot popping-up in the corner of the bottom clip (see [[Special:myLanguage/Kdenlive/Manual/QuickStart#transition|Transition]]).
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.

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.
