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 the Right-Click Menus menu . For more detail see Quick Start.menu item or from Clip in Timeline
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 choose themenu item. Tracks which have effects added in this fashion will have a gold star icon in the track header.
Make the Effects Tab visible use themenu item.
The effects tab has 5 different icons that cause the application to show and hide different categories of effects.
Changed in version 22.08: Main tab now displays all video and audio effects.
By default the effects tab displays the “Main Effects” (Icon 1 selected) which show all video and audio effects.
Icon 2 makes it display all the video effects categories (This option hides the Audio Correction category that is in the “Main Effects” and adds the Misc and Motion categories).
Icon 3 makes it display all the Audio effects categories
Icon 4 is Custom effects
Icon 5 is Favorite Effects. This is the same list that appears in the “Insert an Effect …” context sensitive menu obtained on a clip in the timeline. An effect gets in this list by choosing Add to Favorites from the context sensitive menu on each of the effects.
Icon 6 toggles the information display which - when on - shows a description of what the effect does.
Icon 7 let you download effects users had created and uploaded to the KDE Kdenlive store.
To add an effect to a clip, simply drag it from the Effects Tab to the clip on the Timeline.
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 Quick Start for an example on keyframing the RGB adjustment effect.
New in version 20.08.0.
Effect panels get zoom bars. Adjusting keyframes just get easier.
New in version 20.12.0.
Keyframe have copy/paste icons in the effect keyframe toolbar. Standard shortcuts CTRL + C, CTRL + V
Working with keyframes in the effect stack¶
New in version 21.04.0.

Select the keyframe you want to move
Move the cursor to the position where you want to move the keyframe to
Select the keyframe you want to duplicate
Move the cursor to the position where you want to insert the new keyframe
Exchange keyframes across effects¶
You can import and export keyframes from/to the clipboard. This feature is not only useful to copy keyframes from one clip to another, it can e.g. also be used to copy the results of the motion tracker to a transform effect.
To export the keyframes the clipboard click on inside the keyframe widget and choose .
To import keyframes from the clipboard click on inside the keyframe widget and choose . If you have valid data on your clipboard you should see a dialog similar to the screenshot where you can adjust the mapping of the data.

Time Remapping (Speed Ramps)¶
New in version 21.08.0.
The new Time Remap feature allows to keyframe the speed of a clip.
New in version 21.08.0.
You may now apply effects to only affect specific regions of a clip by using masks. Do note that this is only the initial implementation so expect an improved workflow in the coming releases. For now the process involves 3 steps:
Add one of the 3 available masks: Shape alpha (mask), Rotoscoping (mask) or Alpha shapes (mask).
Add an effect (or effects) to be applied to the masked region.
Add Mask Apply to activate the mask to the effects in step 2.
You may apply more than one mask per clip by following the same 3 step process.
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.
