Zeitleiste

The timeline is the central part of Kdenlive. It is made of four different areas:

Timeline pane

Timeline Areas

1 - Timeline. This is the area where you drop your clips to the various tracks. It shows the clips with or without thumbnails, with or without the audio frequency curve, transitions and compositions, as well as the markers, guides and keyframes (if any).

2 - Timeline ruler. This area shows the time in hh:mm:ss:ff notation. It also shows the current zone (if defined) and the preview render zones and their respective render status. A more detailed description can be found further down here. Left-clicking in the timeline ruler will move the Zeitleiste and seek to that position. For the right-click menu see the detailed description.

3 - Timeline Toolbar - This is an important area where the tools for working with the clips in the timeline are easily accessible. Feel free to adjust the timeline toolbar to accommodate your workflow. For details how to do that refer to the section about toolbar configuration.

4 - Track Header. This area displays track header data like track type (V for video, A for audio), track number, with your without track effects, hidden or muted, locked or unlocked, and an optional track name. Each track can be adjusted in height individually as well as expanded or collapsed. A more detailed description can be found further down here. For the right-click menu see the detailed section.

Zoombars

Zoom-bar

Besides the availability of zoombars in the monitor and keyframe scroll bars, zoombars are now available in the timeline as well. You can easily zoom in/out in the timeline by dragging the edges of the timeline scrollbar. (Vertical zoombars coming soon.) Recommend playing this video in full-screen mode.

Key binding information

context-and-keybinds

Key binding info has been added on the left while context item information has been moved to the right of the Status Bar. Recommend playing this video in full-screen mode.

Timeline visuals

The timeline got a visual overhaul with more and better looking guides/marker colors, the guides have been moved above the timeline ruler while preview and zone bars have been moved below.

Split Audio/Video

splitAV

The way timeline tracks work has changed. Each track is now either audio or video, and will only accept audio and video clips respectively. When dragging an AV clip from the project bin to the timeline the clip will be automatically split with the video part going on a video track, and the audio part on an audio track.

The separation of audio/video is important for implementing same-track-transitions.

Timeline Cursor/Position Caret/Playhead

timeline playhead

This indicates the position we are displaying in the Monitors. You can scroll the position by dragging the Timeline cursor (a.k.a Position Caret or Playhead).

Beginning with version 0.9.4, dragging the timeline cursor will play the audio of the clip (a.k.a. Audio Scrubbing). This feature only works if you have checked Use Open GL for video display in Configure Kdenlive.

Keyboard Navigation

You now have the possibility to move clips and compositions with your keyboard. To do it, select a clip in the timeline and use the Grab Current Item function from the Menu ‣ Timeline menu or use the default shortcut of Shift + G.

Moving clips and compositions with Shift+G

You can then move the item with the arrow keys.

Keyframes can also be moved individually. Just click on a keyframe in the timeline, then move it Left or Right, change its value with + and -. Use Alt + arrow to go to another keyframe.

Moving clip keyframes in the timeline

Keyframe handling

Improved keyframe handling
  • Add a new keyframe by double clicking in timeline.

  • You can move a keyframe without altering its value by using the vertical line that appears when you are above or below a keyframe.

  • Remove a keyframe by dragging it far above or below the clip limits.

Disabling individual clips

Disabling_individual_clips

Individual clips can be disabled while still in the timeline but with no audio and no video – (works for all clip types). Right-click on the clip and choose Disable clip or Enable clip.

Toggle between sequence tabs

With following keyboard shortcuts you can toggle between sequence tabs:

Go to next sequence Ctrl+tab

Go to previous sequence Ctrl+shift+tab

Timeline Ruler

The timeline ruler shows the timecode information in the notation of hh:mm:ss:ff (default) or in frames. It displays the currently defined timeline zone (1) and the preview render zone (2) and its respective rendering status (red: not yet rendered; yellow: being rendered; green: finished).

Timeline Ruler

The timeline zone can be moved by dragging the square in the middle, and sized by either dragging the left or right edge or by positioning the playhead in the timeline and pressing I or O to set in-point and out-point, respectively. For more detailed information on preview render please refer to this section of the documentation.
