Many effects use the concept of "Keyframe". Keyframes are user defined points in your clip where you want and 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 key frames 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 key frames.

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 List 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 effect stack that displays when the clip in question is selected in the timeline.


Effect List

Make the Effects List visible from the View menu (View -> Effect List)

Figure 1

To have a brief description of the effect display at the bottom of the list - click the button as highlighted in figure 1.

To add an effect to a clip simply drag it from the Effect List to the clip.

Effect Stack

Figure 2 shows the effect stack for a clip. The effect stack can be made visible from the View menu Effect Stack

Figure 2

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 X labeled 3 in the image below. The arrow labeled 1 minimizes the effect in the effect stack. And the arrow labeled 2 brings up the menu shown.

Using Keyframes in effects

Many effects use the concept of "Keyframe". 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

Some keyframe controls have a seek to active frame button (labeled 1 in the screen shot A below). When seek to active frame is toggled on and you click on one of the key frames in the keyframe list then Kdenlive will scroll the preview window to that keyframe. In the example of the screen shot we have selected the keyframe at 9:20 in A and the clip position carat (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 effects of a number of the video effects available in Kdenlive (Spanish captioning)

The available effects are defined by .xml files found in $KDEDIR/share/kde4/apps/kdenlive/effects (e.g. /usr/share/kde4/apps/kdenlive/effects)

FAQ:

Q: How to duplicate an effect to use similar settings somewhere else?

A: Select your effect in the timeline, in effects stack widget choose Save, you get it available in Effects 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: How to apply an effect on several clips (all) at the same time?

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