Frise chronologique

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 Frise chronologique 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.

Séparer Audio / Vidéo

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.

La séparation de l'audio et de la vidéo est importante pour implémenter des same-track-transitions.

Curseur de la frise chronologique /Position du curseur / Tête de lecture

timeline playhead

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

À partir de la version 0.9.4, un glisser du curseur de la frise chronologique permet de lire l'audio de la vidéo (alias Nettoyage de l'audio). Cette fonctionnalité ne fonctionne que si vous avez coché Utiliser OpenGL pour l'affichage vidéo dans Configurer Kdenlive.

Navigation au clavier

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.
