Click on edit-download to download more presets created by Kdenlive users. For more details about creating your own presets refer to the Project Profiles section of the documentation.

See also the Render Profile Parameter section for more details about the various settings in the presets.

Full Project

Full Project radio button is the default setting. Kdenlive renders from the start of the first clip until the end of the last clip in the timeline.

Selected Zone

Selected Zone radio button selected, Kdenlive will only render that portion of the project which has a selected zone created for it. See Écrans.

Guide Zone

Guide zone radio button makes use of Guides to define a region of the project that is to be rendered. For more details refer to the Rendering Using Guides section of the documentation.

Guide Multi-Export

Guide Multi-Export radio button makes use of Guides categories to be rendered. For more details refer to the Using Guides for Multi-Export section of the documentation.

More Options


Check this box to get a video track in the rendered file.


Rendering options for video



Interpolation - Allow setting the default interpolation method for scaling operations on rendering

  • Nearest-neighbour interpolation: Sharp but highly aliasing.

  • Bilinear interpolation: Fast and low quality. Reduces contrast.

  • Bicubic interpolation: Slower then Bilinear but better results.

  • Lanzcos interpolation: Provides the best result for scaling



Deinterlacer - Allow setting different deinterlacing algorithm method for interlaced footage on rendering

  • One-Field: Render only one field so the rendered result is half in size.

  • Linear blend: Render each half-picture like a full picture with linear interpolation: instead of rendering each line twice, line 2 is created as the average of line 1 and 3, etc.

  • YADIF - temporal only: Mode of checking fields. Skips spatial interlacing check.

  • YADIF: (Yet Another DeInterlacing Filter) It check pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.

  • BWDIF: (Bob Weaver Deinterlacing Filter): motion adaptive deinterlacing based on yadif with the use of w3fdif and cubic interpolation algorithms.

Render full color range - Check this box if you need 10-bit color instead of 8-bit color. Please note that this does not work with effects (yet).

Render at Preview Resolution - Check this box if you want to use the same resolution as set in the Project Monitor. Useful for quick renderings to check or verify things.

Use Proxy Clips - Check this box if you want the use the proxy clips for rendering. Useful for quick renderings to check or verify things.

Rescale - Select this if you want the rendered video to have a different resolution than what is set in the Project Settings. Useful for quick renderings to check or verify things.


Render overlay

Render Overlay - This option overlays a time code or frame count over the rendered video. The overlay will be over the entire rendered project. Alternatively you can use the Dynamic Text effect to overlay selected regions of the video.


Aspect Ratio

Aspect Ratio - With this option you can choose your desired aspect ratio for the rendered video. It passes the selection to the rendering profile by cropping the video in the timeline to the desired aspect ratio.


Check this box to have audio tracks in the rendered file.


Rendering options for audio

Separate file for each audio track - By default, Kdenlive creates a stereo audio track. Use this option if you want multiple audio tracks (for example for different languages or commentary) that can be selected in the player software. Use a third-party software to put the video and audio files together.

Custom Quality


Rendering options for custom quality

Check this box if you want to manually adjust the quality settings for the rendering process. Use the slider to dial in the quality settings. This has an influence on file size and rendering time.



Rendering options for encoder usage

Use the slider to change the speed setting from 'very slow' to 'ultra fast'.

If you have a CPU capable of multi-threading you can select the number of Encoding threads to be passed to melt [1]. For encoding with certain codecs (MPEG-2, MPEG-4, H.264, and VP8) Kdenlive can use more than one thread and thus make use of multiple cores. Increase this number to take advantage of this feature on multi-core machines.

Parallel Processing


Rendering options for parallel processing

Switch this on to further reduce rendering time. Once enabled you can select the number of threads to use. A good number is 50% of what your CPU's number of possible threads is (e.g. 8 threads for a 16-thread CPU).


Parallel Processing is still (version 23.04.1) somewhat experimental and may result in rendering artifacts, crashes during render or other unwanted effects.

Other Options

Export metadata - Check this box to have the metadata entered in the Boîte de dialogue pour la configuration du projet placed into the metadata of the rendered file.


Metadata for the project

In this example, metadata was entered in the Project Settings dialog.

You can edit this by clicking on the Edit metadata link in the rendering dialog (More options must be checked). For this example a new field Kdenlive Version was added (using +) and a value of 23.04.1 entered.

You can check the metadata in the rendered video by entering this in a terminal window:

$ ffprobe <your_video>

Other rendering options

Embed subtitles instead of burning them in - Creates a stream for subtitles in the container (e.g. MKV)

Open folder after export - Opens the folder where the file was saved in the default file manager application

Play after render - Opens the default media player application and plays the rendered file

Rendering in Batch Mode

If you have a lot of rendering jobs to do, you can use Kdenlive to create rendering scripts which you can accumulate and then execute in batch mode overnight. Kdenlive stores the scripts in the folder specified in Menu ‣ Settings ‣ Configure Kdenlive ‣ Environment ‣ Default folders.

Alternatively, once you have submitted a rendering job on a project and it is up and running in the Job Queue, you can drag the render window out of the way or even close it, and continue editing the project, or load a new project and render that one, too. Any subsequent render jobs will go into the Job Queue. Editing the project after a render job has been submitted will not change the settings on that job.


Rendering Using Guides

Guides can help organize your project while you work on it and when you share it with the world. You can use guides to keep track of areas or to generate rendering scripts that will do the mundane task for you. This feature makes exporting sections of your project quite easy.

For more details about guides, how to add and manage them, refer to the Guides section of the documentation.

Using Guide Zones


Using guide zones to render a section

With this option you define the start and end point for the render by selecting specific guides.

Generating Rendering Scripts

kdenlive2304_rendering-guide_zones_5a kdenlive2304_rendering-guide_zones_5b

Choose which guides will establish the regions of video you want to export using the pull down menus next to From and to. In this example Section 1 to Section 1 End will be used to define the section to be rendered.


Now you can render this to a file or generate a script that will render this guide zone to a file. Click Generate Script and a dialog appears asking you to name the script. Kdenlive stores the clips in the folder specified in Menu ‣ Settings ‣ Configure Kdenlive ‣ Environment ‣ Default Folders.


After saving the script, the top tab in the window switches to Scripts. This lists all the scripts you have generated, including scripts from other projects.

In this example three scripts were created based on the guides in the timeline. Be sure and keep the .mlt extension otherwise the rendering script will not be generated.

Starting Your Rendering Scripts

Each script needs to be started individually by selecting the script and clicking the Start Script button.


After clicking each script, Kdenlive switches to the Job Queue tab. Here you will see what script is being run and how many more are waiting to be run. If you have a large queue and you want to run the rendering after hours, you can take advantage of the nifty checkbox in the bottom left: Shutdown computer after renderings

Starting Your Rendering Scripts in a Command Line Terminal

For troubleshooting purposes there could be times that you want to run the render script from the terminal prompt. Rendering in the terminal can produce error logging information that can assist in debugging rendering issues.

To render the video in the terminal ...

  • Note the location where Kdenlive has saved the script

  • Open a terminal and change directories to the location of the .mlt script

  • Run melt with the .mlt script

$ cd /path/to/kdenlive/scripts

$ melt your_script.mlt

Using Guides for Multi-Export

With this option you use guides to divide the timeline in pieces that will be rendered as individual files on one go. You do not need to define each section or piece individually.

render guide multi-export example 22-04

Defined Guides to be used for multi-export

The selection of guide categories indicates which guides will be considered for rendering.

In this example, there are the following options:

  • "All Categories": This leads to four files:

  • projectname-begin.mp4 (from 00:00:00 to "guide1")

  • projectname-guide1.mp4 (from "guide1" to "guide2")

  • projectname-guide2.mp4 (from "guide2" to "guide3")

  • projectname-guide3.mp4 (from "guide3" to the end)

  • "Category 0 (purple)": This leads to three files:

  • projectname-begin.mp4 (from 00:00:00 to "guide1")

  • projectname-guide1.mp4 (from "guide1" to "guide2")

  • projectname-guide2.mp4 (from "guide2" to the end)

  • "Category 1 (blue)": This leads to two files:

  • projectname-begin.mp4 (from 00:00:00 to "guide3")

  • projectname-guide3.mp4 (from "guide3" to the end)


  • If guides are behind the last timeline clip, they are ignored.

  • If a guide sits right at the beginning of the timeline, the name of that guide is used instead of "begin".

  • If two guides have the same name, an underscore and a number will be added to the file name.


As of this writing, the appimage of version 23.04.1 is having issues with the scripts generated with this function. Only one of the scripts is executed successfully but the other scripts remain in status 'Waiting...'. Unfortunately, a manual start of the scripts is not possible either.
