Editing

Editing is done in the Timeline. Add a clip by dragging it from the project bin or the Monitors. Once a clip is dropped on a track, it can be moved (drag and drop it) to another place on the same track or onto another track.

add clip to timeline

Editing with keyboard shortcuts can speed up the editing work, and you can do editing steps that are not possible or not as quick and easy with the mouse. Working with keyboard shortcuts from version 19.08 onwards is different as in previous Kdenlive versions. Mouse operations have not changed and work as before. See 3 Point Editing

Seeking through your project

The timeline cursor shows your current position in the project. The positions of the cursors on the timeline ruler and Project Monitor are always in sync. Position can be moved in the following ways:

  • Keyboard shortcut: right / left arrows for one frame, Shift+ right / left for 1 second

  • Clicking/dragging in the Timeline or in an empty area of the timeline.

  • Clicking/dragging in the Monitors ruler.

  • Rotating the mouse wheel while the pointer is over the Timeline or over the Monitors

  • Editing the timecode in the Monitors timecode widget

  • Clicking the up or down arrows on the Monitors timecode widget

Cutting a Clip

To cut a clip, the easiest way is to place the timeline cursor where you want to cut the clip, then select the clip (left click in it) and use the menu Timeline ‣ Current Clip ‣ Cut Clip (default shortcut: Shift + R).

Or Right Click ‣ Cut Clip

Alternatively - use the Spacer Tool.

Resizing a Clip

A clip can be resized from its start or end by dragging its left or right edge. If you want a more precise resize, you can place the timeline cursor wherever you want the resize to end and use the menu Timeline ‣ Resize Item Start (default shortcut: ( or Timeline ‣ Resize Item End (default shortcut: ))

To even more precisely control the length of a clip, double click it in the timeline and adjust its duration using the Clip duration dialog. You can have frame-level accuracy with this method.

clip duration

You can also resize a clip by cutting it with the Razor Tool and then deleting the bit you do not want.

Adjust AV clips independently with Shift + resize to resize only audio or video part of a clip.

alt + Move in timeline allows to move the audio or video part to another track independently.

resize clip yellow indicator

Select a clip in the project bin. When resizing this clip in the timeline the clip monitor shows a yellow indicator relative to the original clip length.

Edit an Animation

注釈

This requires Glaxnimate version >= 0.5.1

Double click on an animation clip in the timeline and this will open Glaxnimate.

Animation with background

The background of the animation in Kdenlive will also be shown in Glaxnimate.

Glaxnimate with background

It is possible to have several Glaxnimate instances open, but the background will only be send to the one opened first in Glaxnimate. If you like to see the Kdenlive background of another animation clip, save the animation and close Glaxnimate before you double click another animation clip.

Change Speed of a Clip

adjustspeed

Adjust the speed of a clip by pressing CTRL + dragging a clip in the timeline.

Doing with right click on the clip see Change speed.

Removing Space Between Clips

Right click in the space between the clips and choose Remove Space. Be aware however that if you have clips on multiple tracks in the timeline and they are not grouped, then removing space may disturb the alignment of the clips between the different tracks – the space is only removed from the timeline where you clicked. Under this situation it may be safer to use the Spacer Tool.

remove space

Timeline ‣ Current track ‣ Remove All Spaces After Cursor

It handles AV clips as 1 element, doesn't matter on which track they are. This function is only in the Timeline menu available this to avoid clutter.

More details see Remove Space / Remove Space in All Tracks.

Track Compositing

The track compositing applies uniformly to all tracks in your timeline.

Tip

Under certain compositing conditions, if you see the outcome of a transition not to be what you would expect, try to switch track compositing off for a quick check. If the oddity is gone, then this is an interference between the automatic timeline track compositing and your user transitions.

Track compositing is now a simple checkbox instead of the none/high resolution choice.

High Quality

バージョン 22.08 で非推奨.

When track compositing is set to High-Quality tracks with alpha channel information will be automatically composited with the other tracks using an algorithm that is somewhat slower than the algorithm used with Preview but which retains higher fidelity color information.

None

バージョン 22.08 で非推奨.

When Track Compositing is set to None you will not get tracks with alpha channel information to composite with the other tracks unless an explicit composite or affine transition is added between the clips. This is basically kind of an expert mode when you need full control over any compositing in your timeline.

Preview

バージョン 21.08 で非推奨.

注釈

Final rendering always uses either High Quality or None. So Preview quality is, well, for preview only.

When track compositing is set to Preview tracks with alpha channel information will be automatically composited with the other tracks using an algorithm that is somewhat faster than the algorithm used with High Quality but which slightly degrades the colors.

Active track

Editing active track

An active track

1 Target track (3-point editing). The highlighted target strip indicates that in the project bin an A/V clip is selected (the selected clip has an audio and video part).

2 Active track (3-point editing)

3 Track header

4 Empty part of the track

Only active tracks can accept clips or react to an edit function. An active track is indicated by a:

  • highlighted track number (2) (for 3-point editing)

  • blueish or brownish track (3 4) (depends on the color scheme), working with the mouse or insert clip by paste

When you work with the mouse Kdenlive make a track active as you drop a clip to the timeline or you select a clip.

Make a track active by:

  • click into the track header (3)

  • double click into an empty part of the track (4) (the playhead moves to this point too). This is useful when you copy & paste clips.

  • 1-9 select a video track

  • alt+1-9 select an audio track

  • arrow key up/down

For 3-point editing

  • Alt+Shift+A Switch all tracks active

  • Shift+A Toggle all tracks active/inactive

  • A Toggle track active

  • Shift+T Toggle track target

Here you find more timeline shortcuts.

Timeline Edit Modes

Normal Mode

In this edit mode, you can not drag clips on top of other clips in the same track in the timeline. You can drag them to another track in the timeline but not into the same track at the same time point as an existing clip. Contrast this to overwrite mode.

Overwrite Mode

In this edit mode, you can drag a clip onto a track where there is an existing clip and the incoming clip will overwrite that portion of the existing clip (or clips) covered by the incoming clip.

kdenlive_overwrite_mode_after01

Before

kdenlive_overwrite_mode_after01

After

In the "After" screenshot above, you can see that the clip which was dragged from the upper track has replaced a portion of the clip on the lower track.

Rearrange clips in the timeline

Performing a rearrange edit. This technique lets you quickly change the order of clips in the timeline.

Overwrite-mode

Drag a clip, as you drop it to a new location performs an overwrite edit that overwrites the existing clip.

Insert Mode

With this mode selected and you drop a selection into the timeline the selection will be inserted into the timeline at the point where the mouse is released. The clip that the selection is dropped on is cut and clips are moved to the right to accommodate the incoming clip.

Kdenlive_Insert_mode0before

Rearrange edit in the timeline

Performing a rearrange edit. Only clips in the destination track are shifted; clips in other tracks are not affected. This technique lets you quickly change the order of clips in the timeline.

It always closes all space in the track.

Insert-mode

Drag a clip, as you drop it to a new location. Releasing the clip performs an insert edit that shifts clips in the destination track only.

Timeline Edit Tools

Selection Tool

Use this to select clips in the timeline. The cursor becomes a hand when this tool is active.

Razor Tool

Use this to cut clips in the timeline. The cursor becomes a pair of scissors when this tool is active.

ESC: Return from any tools back to Selection tool.

Spacer Tool

Use this tool (distribute-horizontal) to temporarily group separate clips and then drag them around the timeline to create or remove space between clips. Very useful. Experiment with this tool to see how it works.

spacer tool crop

In the above example, these clips are not grouped. However, the spacer tool groups them temporarily for you so you can move them all as a group.

ESC: Return from any tools back to Selection tool.

Slip Tool

slip tool

Slip keeps the original duration of the clip. Like working with old film material: beneath the given "window" of the clip length it slips the film strip back and forth.

slip tool in action

Use Slip (kdenlive-slip) to trim, in a single operation, the IN and OUT points of a clip forward or backward by the same number of frames, while keeping the original duration and without affecting adjacent clips.

You can slip multiple clips at once now: select all clips you want to slip with the selection tool using Shift then enable the slip tool and go ahead…

Slip can be done with the mouse, with the arrow keys and with the buttons on the monitor toolbar.

ESC: Return from any tools back to Selection tool.

Ripple Tool

ripple tool

Ripple changes the original duration of the clip. Like working with old film material: You lengthen or shorten the film strip and move the adjacent clips back and forth as you do that.

Use Ripple (kdenlive-ripple) to trim a clip and shift following clips in the track by the number of frames you trim. When you shorten a clip by this action all clips that follow the cut shift back in time, contrariwise, when you extend a clip the clips after the cut shift forward in time. If an empty space is on the track it behaves as a clip and it shifts in time as a standard clip would be.

You can Ripple only a single clip at once.

Ripple can be done with the mouse only.

ESC: Return from any tools back to Selection tool.

Ripple Trim to Playhead

To cut a clip on an active track at the playhead position without getting a gap in the timeline do the following.

  • enable ripple

  • place the playhead at the desired place

  • hit (: This cuts and removes the clip and space to the left side of the playhead. ) does the same but to the right side of the playhead.

Multicam Tool

multicam tool

The multicam tool allows to cut between several cameras while playback is running. Add your clips in different tracks, but at the same position in the timeline and activate the multicam tool by going to menu Tool -> Multicam tool. You may trim the clips in the desired track while the timeline is playing by pressing their corresponding numbers (for track V1, press key 1; for track V2 press key 2, etc…) or simply select the desired track in the project monitor by clicking on it with the mouse.

Select multicam tool will switch on the Multitrack View in the project monitor and set a marker at the current timeline position. You can then seek/play to the wanted position, click on a track view in the project monitor and it will lift all tracks except for the previously active track. You can then repeat seek and click in another track to continue lifting tracks.

It doesn't stop playing when you perform the operation to avoid to lose the rhythm and to work as you are working during a live broadcasting. If you need to correct the editing you can manually stop and trim the cut as you do when you video editing as normal.

The audio tracks is not involved in the process as you generally use only one audio track (the one which come from the main mixer to which the other ones are synced to)

Split Audio and Video Automatically

When this is on and you drag a clip to the timeline, the audio in the clip will end up on an audio track and the video on a video track. You can achieve the same result if you select the clip, Right-Click Menus, Split Audio. When this is off and you drag a clip onto the timeline, both the audio and video tracks are combined into one video track.

Show Video Thumbnails

When on, the video clips in the timeline will contain thumbnails as well as a filename. Otherwise, they just have the clip filename.

When the timeline is zoomed in to the maximum, the video track will show a thumbnail for every frame in the clip. When the timeline is not on maximum zoom, the video track will show a thumbnail for the first and last frame in the clip.

Show Audio Thumbnails

When on, the audio clip will have a wave representation of the audio data as well as a filename. Otherwise, they just have the clip filename.

Show marker comments

This toggles on and off the display of Markers saved within clips (the text with the gold background in the example below) and within Guides (the text with the purple background).

markers and guides

Snap

When this feature is on, dragging the beginning of one clip near to the end of another will result at the end of the first clip snapping into place to be perfectly aligned with the beginning of the second clip. As you move the two ends near to each other, as soon as they get within a certain small distance, they snap together so there is no space and no overlap. Note that this occurs even if the clips are on different tracks in the timeline.

Clips will also snap to the cursor position, markers and Guides.

Fit Zoom to Project

This will zoom the project out so that it all fits in the timeline window. This is the same function that is triggered by Timeline Menu Menu item, Fit Zoom to Project.

Zoom project

The magnifying glasses zoom in or out on the timeline. The slider adjusts the zoom by large increments. These same settings are controlled by the Timeline menu items, Zoom In and Zoom Out.

Cutting Footage from multiple aligned tracks - Ripple Delete

There are 4 possibilities for ripple delete (point 1 and 2 are the classical Ripple Delete):

  1. On the active track: Cut out the piece on the clip which you do not want with Shift+R. Right click on that piece and choose Extract Clip. This removes the clip and slides everything else to the left to fill the gap. The playhead stays were you made the last cut.

  2. On the active track: Empty spaces between clips can only be removed by right click on empty space and choose Remove Space.

  3. On all tracks together: Mark In and Out points in the Project Monitor or on the Timeline, then choose Timeline ‣ Removal ‣ Extract Timeline Zone (or Shift+X). Kdenlive deletes all footage between the In and Out points in unlocked tracks, slides everything else back to fill the gap, and puts the playhead on the In point.

  4. On the active track with Insert Mode: Cut out the piece on the clip which you don't want with Shift+R. Hit Delete. This removes the clip and slides everything else to the left to fill the gap. The playhead stays were you made the last cut.

You can do a ripple trim to the playhead using Ripple Trim to Playhead.

3 point editing

3 important points to understand the 3 point editing concept (with keyboard shortcuts):

Source

3point source

On the left of the track head the green vertical lines (V1 or A2). The green line is connected to the source clip in the project bin. Only when a clip is selected in the project bin, the green line shows up depending on the type of the clip (A/V clip, picture/title/color clip, audio clip).

Target

3point target

In the track head the target V1 or A1 is active when it’s yellow. An active target track reacts to edit operations like insert a clip even if the source is not active.

The concept is like thinking of connectors

Connect the source (the clip in the project bin) to a target (a track in the timeline). Only when both connectors on the same track are switched on the clip “flow” from the project bin to the timeline.

重要

Active target tracks without connected source react on edit operations.

Examples of advanced edit

Here is a brief introduction to the 3 point editing system.

3point insert
  1. Select a clip in the project bin with an up/down arrow

  2. Navigate the clip by the JKL keys or by the left/right arrows and set the IN and the OUT point by the I and O keys.

  3. Hit T to change to the timeline

  4. Select a video or audio track in the timeline (up/down arrow key) and set it as source with Shift + T.

  5. Activate the track as a target with shortcut A (this connects the track to the source)

  6. Hit V (insert) or B (overwrite) to add the clip at the play-head position or to fill the selected area in the timeline if it is active. If you need to activate it use the G key.

3point edit

In the following example, we want only to insert the audio part of a clip in A2 and we want to create a gap in all the other video and audio tracks:

  1. Activate all the target tracks which contain clips (yellow buttons).

  2. Activate just the audio source on A2

  3. Press V (insert).
