Monitors
Kdenlive uses 2 monitor widgets to display your videos: Clip Monitor and Project Monitor. A third monitor - the Record Monitor - previews video capture. These monitors can be selected by clicking the corresponding tabs which appear at the bottom of the monitor window.
Resizing the Monitors
You can resize the monitors by dragging the sizing widget. It is a bit tricky to find the bottom widget. You need to hover just between the bottom of the monitor tab and the timeline
Since version 19.04.0
Support for external monitor display using Blackmagic Design decklink cards.
Monitor toolbar
Since version 19.04.0
Support multiple guide overlays. Move with the mouse to the upper-right corner of the monitor to access the toolbar.
Preview resolution
Since version 20.04.0
Preview resolution speeds up the editing experience by scaling the video resolution of the monitors. It can be used of proxies instead.
Clip Monitor
The Clip monitor displays the unedited clip that is currently selected in the Project Tree.
Widgets on the Clip Monitor
1) Set zone start button - click this to set an 'in' point.
2) Set zone end button - click this to set an 'out' point.
3) Zone duration indicator - selected by setting in and out points. Dragging the clip from the clip monitor to the timeline when there is a selected zone causes the selected zone, not the entire clip, to be copied to the timeline.
4) Position Caret - can be dragged in the clip. (In ver >=0.9.4 and with OpenGL turned on in Settings -> Configure Kdenlive -> Playback, audio will play as you drag this.)
5) Timecode widget - type a timecode here and hit Enter to go to an exact location in the clip. Timecode is in the format hours:minutes:seconds:frames (where frames will correspond to the number of frames per second in your project profile).
6) Timecode arrows - can be used to change the current position of the clip in the clip monitor.
Creating Zones in Clip Monitor
Zones are defined regions of clips that are indicated by a colored section in the clip monitor's timeline - see item 3 above. The beginning of a zone is set by clicking [ (item 1 in the pic above). The end of a zone is set by clicking ] (item 2 in the pic above)
The Clip Monitor has a right-click (context) menu as described here.
Drag audio or video only of a clip in timeline
Since version 19.04.0
Move with the mouse to the lower-left corner of the clip monitor to access the Video/Audio icons. Hover with the mouse either over the audio or video icon left click to drag either video or audio part into the timeline.
Project Monitor
The Project Monitor displays your project's timeline - i.e. the edited version of your video.
Project Monitor Widgets
1) The position caret. Shows the current location in the project relative to the whole project. You can click and drag this to move the position in the project.
2) The timecode widget. You can type a timecode here and press Enter to bring the Project Monitor to an exact location.
3) Timecode widget control arrows. You can move the Project Monitor one frame at a time with these.
Creating Zones in Project Monitor
You can use the [ and ] buttons to create a zone in the Project Monitor the same way you make zones in the clip monitor. The zone will be indicated by a colored bar both on the timeline and underneath the Project Monitor.
You can get Kdenlive to only render the selected zone - see Rendering Using the Selected Zone Option.
The project monitor has a right-click (context menu) as described here.
Multicam Editing
Since version 20.04.0
New multicam editing interface allows you to select a track in the timeline by clicking on the project monitor.
Record Monitor
There is also a Record monitor that can be used to preview capture from Firewire, Blackmagic cards or through FFmpeg / video4linux.
Until version 18.12: To switch to the record monitor click in the clip monitor on the “+” sign.
Until version 18.12: To switch back to the clip monitor click in the record monitor the “+” sign.
Version 19.04 and newer
Screen record is moved to → Screen Grab
Separate Clip and Project Monitors
You can click on the Tab names that label the Monitors and drag the monitor out into its own window.
To put the monitors back into the Tabbed view - click on the monitor's title bar and drag the window on top of the other monitor window.
If the monitor has no title bar (intermittent defect) then you can not do this and you will need to reset kdenlive settings by deleting ~/.config/kdenliverc
