    Effects

    Effects in Kdenlive can be used to modify the audio and video properties of the source material.

    You add effects to clips by choosing them from the Effects Tab and dragging them onto a clip in the timeline. Or by selecting a clip in the timeline and choosing Add Effect from the Timeline menu or Add Effect from Clip in Timeline right click menu . For more detail see QuickStart - Effects

    The effects that are in play on a given clip can be viewed and edited via the Properties Tab that displays when the clip in question is selected in the timeline.

    You can also apply effects to an entire track. This is achieved by dragging an effect from the Effect Tab to the Track Header. Or you can click on the track header and chose Add Effect from the Timeline menu . Tracks which have effects added in this fashion will have a gold star icon in the track header.

    Effects Tab

    Make the Effects Tab visible from the View menu (View -> Effects)

    Figure 1b - effects tab. The Information icon has been toggled so that the tab displays a brief description of the selected effect at the bottom


    To add an effect to a clip, simply drag it from the Effects Tab to the clip on the timeline.

    The Properties Tab and its Menu

    The Properties Tab

    The Properties Tab displays the settings for the effects on the currently selected clip (Figure 3) or the settings for the currently selected transition (Figure 4) depending on whether it is a clip or a transition that is currently selected.

    Figure 3 - Properties when a clip with effects is selected
    Figure 4 - Properties when a transition is selected

    Click the eye icon shown at 2 to temporarily disable the effect and toggle the button to the state shown at 1. Click the empty eye icon shown at 1 to re-enable a disabled effect and toggle the button to the state shown at 2.


    To remove an effect from a clip, click the trash can icon labelled 3 in the image below. The arrow labelled 1 minimizes the effect in the Properties Window. And the icon labelled 2 brings up the Properties Tab menu shown.

    Reset Effect

    This reverts all the settings in the effect back to their default values.

    Save Effect

    This allows you to save the current effect and all its settings. The saved effect will appear in the Effect List in the Custom category.

    Create Group

    This creates an Effect Group. An Effect Group is a place holder for multiple effects. You can then save the group of effects — they will the appear in the Effect List, in the Custom Section. You can then later apply the whole group of effects to other parts of the timeline.

    To add effects to the group, first add the effect in question to a clip. Then drag that effect and drop it onto the Effect Group in the Properties Tab.

    Create Region

    New in ver >=0.9.3

    The "Create Region" feature enables a user to apply an effect to a part of a clip only. It is a really powerful feature but currently the UI is not fully ready to get its full potential.

    Basically, you add an effect to a clip — for example "Sepia" — then you go in the effect's menu and select "Create Region". This will now open a file dialog.

    In that dialog, you need to point to an MLT clip with alpha transparency. This is where Kdenlive is not 100% ready because there are many ways we could create such clips, using for example a threshold filter or rotoscoping. But as a start, let's say you can open any image with alpha transparency, or a title clip created with Kdenlive. Then, the "sepia" effect will only be applied on the non-transparent areas of this "region" clip.

    Using Keyframes in effects

    Many effects use the concept of "Keyframes". Keyframes are user-defined points in your clip where you want an effect to start, stop or change. You can set the parameters for your effects to different values at different keyframes and Kdenlive will then gradually change the parameters between the two keyframes so that by the time the video has arrived at the next keyframe it will have adjusted the parameter to match that key frame. It interpolates between keyframes.

    See QuickStart - Effects for an example on keyframing the RGB adjustment effect.

    Seek To Active Frame

    Some keyframe controls have a seek to active frame button (labeled 1 in screenshot A below). When seek to active frame is toggled on and you click on one of the keyframes in the keyframe list, Kdenlive will scroll the preview window to that keyframe. In the example of the screenshot, we have selected the keyframe at 9:20 in A and the clip position caret (highlighted in red box) shows the location of this keyframe. Clicking the keyframe at 10:00 in B shows how the clip position has moved.

    Effects Demos

    The following three YouTube videos display the results of a number of the video effects available in Kdenlive (Spanish captioning).

    Effekt Kategorien

    See also Effects and Transitions for an alphabetical list of effects and transitions.

    The effects are divided into the following categories:

    1. Alpha manipulation
    2. Analyse und Daten
    3. Artistic
    4. Audio
    5. Audiokanäle
    6. Audiokorrektur
    7. Blur and hide
    8. Farbe
    9. Farbkorrektur
    10. Crop and transform
    11. Benutzerdefiniert
    12. Distort
    13. Enhancement
    14. Fade
    15. Misc
    16. Bewegung

    Die verfügbaren Effekte sind durch .xml Dateien definiert, die sich unter $KDEDIR/share/kde4/apps/kdenlive/effects befinden (z.B. /usr/share/kde4/apps/kdenlive/effects).
    Oder unter /usr/share/kdenlive/effects in Version 15.n.

    Diese .xml Dateien beinhalten die Standartwerte der Effektparameter. Wenn Ihnen die Standartwerte nicht gefallen, können Sie sie also durch bearbeiten der .xml Dateien anpassen.

    FAQ:

    Q: Wie dupliziert man einen Effekt um die gleichen Einstellungen an einer anderen Stelle auch zu verwenden?

    A: Select your effect in the timeline. In the Properties Tab choose Save (from the Properties Tab Menu). You will now find this effect available in the Effect List Custom section.

    A: Other solution: select a strip containing the effect, Copy, then, where you want to apply it again, right-click and select Paste effect instead of Paste.

    Q: Wie fügt man einen Effekt zu mehreren Clips gleichzeitig hinzu?

    A: You can select multiple clips with Shift + drag (left mouse button) around them. Then right-click and group clips (or Ctrl + G).
