Edit Menu
Undo
Edit ‣ Undo is used to reverse the last change you made or operation you performed in Kdenlive. If you have made multiple changes to your project, Undo can be used repeatedly to rollback each of the changes in the reverse order they were performed. Undo can also be executed from the icon on the Extra Toolbar (Menu ‣ Settings ‣ Toolbars Shown) or by using the default keyboard shortcut Ctrl+Z.
To view a navigable list of all the changes which can be undone, see Undo History.
Redo
Menu ‣ Edit ‣ Redo reverses the previous Undo operation. The default keyboard shortcut is Ctrl+Shift+Z.
Clear Undo History
Menu ‣ Edit ‣ Clear Undo History clears the undo history and will free the undo operation in memory for the current project. It will discard all undo history, so you cannot undo anymore.
For more information see Undo History.
Cut
Cuts a clip selected in the timeline to the clipboard. The default keyboard shortcut is Ctrl+X. It also copies the effects attached to the clip to the clipboard. Use Paste to paste the clip into a different spot on the timeline. Use Paste Effects to paste just the effects from the copied clip onto a different clip or group of clips.
Copy
Copies a clip selected in the timeline to the clipboard. The default keyboard shortcut is Ctrl+C. It also copies the effects attached to the clip to the clipboard. Use Paste to paste the clip into a different spot on the timeline. Use Paste Effects to paste just the effects from the copied clip onto a different clip or group of clips.
Paste
Pastes an existing clip in the clipboard into a different spot on the timeline (where the playhead is, to be exact). The default keyboard shortcut is Ctrl+V.
Add Effects
This menu item will open a flyout with all the effect categories from which you can then select an effect to be added to the track effect stack. See also the Effects and Filters section of the documentation.
Paste Effects
You need to have selected a clip and copied it first. Then select another clip or a group of clips. Paste Effects then pastes just the effects from the previously selected clip to the newly selected clip or group of clips.
Remove Effects
Deletes all effects from the selected clip. *[RGB]: Red Green Blue *[VFX]: Visual Effects *[feathering]: Smoothing or blurring the edges of a feature *[LFO]: Low-Frequency Oscillation *[dB]: decibel *[LUFS]: Loudness Units Full Scale *[AI]: Artificial Intelligence *[LLM]: Large Language Model *[HSV]: Hue, Saturation, Value *[SOP/Sat]: S(lope), O(ffset), P(ower) / SATuration *[CDL]: Color Decision List *[HSL]: Hue, Saturation, Lightness - Using HSL color space is useful for subtle color changes *[px]: pixel *[hh:mm:ss:ff]: hours:minutes:seconds:frames *[Hz]: Hertz *[CIE]: Commission internationale de l'éclairage, French for International Commission on Illumination *[DCI]: Digital Cinema Initiative *[nadir]: direction pointing directly below a particular location *[OS]: Operating System *[decibel]: Unit of measurement (dB) for sound levels *[clipping]: A form of distortion that limits a signal once it exceeds a threshold *[Spectrogram]: Visual representation of the spectrum of frequencies of a signal as it varies with time *[prevent clipping]: Dynamic range compression (DRC)is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range. *[SNR]: Signal-to-Noise Ratio *[dbFS]: Decibels relative to full scale *[QHD]: Quad-HD *[UHD]: Ultra High Definition *[XML]: Extensible Markup Language *[fps]: frames per second *[NTSC]: National Television Standard Committee - defined the TV system used in the United States, Japan and many other countries *[PAL]: Phase Alternating Line - a colour encoding system for analogue television *[LFE]: Low Frequency Effects *[RAW]: The RAW file format is digital photography's equivalent of a negative in film photography: it contains untouched, raw pixel information straight from the digital camera's sensor *[DSLR]: Digital Single Lens Reflex *[DOF]: Depth of Field *[NDF]: Neutral Density Filter *[AVI]: Audio Video Interleave *[BT.601]: A standard from 1982 defining how RGB color primaries get turned into the YCbCr channels used by modern codecs *[BT.709]: A standard from 1990 which does the same at BT.601 but the transfer coefficients are slightly different *[grep]: A Unix command-line utility for searching plain-text data sets for lines that match a regular expression *[MLT]: Media Lovin' Toolkit - An open source software multimedia framework designed and developed for tv broadcasting *[SD]: Secure Digital - a proprietary, non-volatile, flash memory card format developed by the SD Association *[SFX]: Special Effects *[VBR]: Variable Bit Rate *[HD]: High Definition *[GUI]: Graphical User Interface
