The Kdenlive.org website is no longer the central collaboration platform for writing documentation, publishing tutorials and translating Kdenlive software. Kdenlive has become part of the KDE team. Documentation and tutorials are now found on
Kdenlive is a long term project and it took 20 years to build Free Tools in video. We have the goal to produce a very accurate and complete documentation on Kdenlive and video editing in general. But this will be done step by step, writing documentation during months. Don't expect immediate results.
The Kdenlive manual has moved to the KDE userbase Wiki (http://userbase.kde.org/Kdenlive/Manual). If you want to contribute then create an account on that wiki and edit away.
Kdenlive manual is written in simplified English and then translated into several languages. The KDE userbase wiki is built with translation in mind.
You can select Open in the File menu
It provides several features.
Kdenlive provides several features.
The management rules for writing documentation are simple:
Do not use chat systems. Use the forum for any discussion. Whenever you agree on the forum, there is more commitment than a simple chat with no trace.
If you have created custom images for Wipe transitions, you can share them with other users by uploading them to:
kde-files.org, in the category Kdenlive.
Wipe images are greyscale images in the pgm format and can be used to transition from one track to another. Once a Wipe image file is uploaded to kde-files.org, it can be automatically installed by all Kdenlive users from the "Settings > Download New Wipes..." menu entry.
Sample luma image:
If you have created custom rendering profiles in Kdenlive, you can share them with the other users. This can be especially useful for example if you created a rendering profile that creates videos for a portable device. In that case, you can browse the list of existing profiles and modify or create a new one. Unfortunately the Create Rendering Profile page is only available to users logged in to kdenlive.org and kdenlive.org is not taking on new members.
Once a rendering profile is created on the website, it can be automatically installed by all Kdenlive users (requires Kdenlive >= 0.7.3) from the menu "Settings > Install New Profiles...".
Since november 2011, Kdenlive has moved to the KDE infrastructure. It means that all our translations are now managed by the KDE translation teams. If you want to help translating Kdenlive in your language, the first thing to do is to get in touch with the KDE localization team: http://i18n.kde.org/
There is a team for each language and you can get infos here.
After that, we recommand using the Lokalize tool which was designed to make KDE translations easier. Here is a quick howto, but please Don't forget to contact the translation team for your language so that the work is not done twice.
If you have questions, you can always contect the Kdenlive developers on the Kdenlive mailing list
For developers, the steps to participate are as follows:
Like in any good free software project, the GUI and the framework rely on different projects:
Most of time, new features need to be added to MLT and Kdenlive.
As a rule, you should be able to play any video editing project using melt and Kdenlive.
MLT has several GUIs, including Kdenlive. We do not accept new features which cover only Kdenlive and not MLT. We would like to make possible for other developers to work on other interfaces.
The below information is likely out of date. See https://community.kde.org/Kdenlive/Development for more up-to-date information about development environments.
We recommend using a Debian SID distribution. It is updated very rapidly on the contrary of Ubuntu, which lacks months behind.
You can use the following /etc/apt/sources.list:
deb http://ftp.fr.debian.org/debian/ experimental main contrib non-free
deb-src http://ftp.debian.org/debian/ experimental main contrib non-free
deb http://ftp.fr.debian.org/debian/ unstable main contrib non-free
deb-src http://ftp.debian.org/debian/ unstable main contrib non-free
deb http://ftp.fr.debian.org/debian/ testing contrib non-free main
deb-src http://ftp.fr.debian.org/debian/ testing contrib non-free main
deb http://ftp.fr.debian.org/debian/ stable contrib non-free main
deb-src http://ftp.fr.debian.org/debian/ stable contrib non-free main
deb http://www.debian-multimedia.org sid main
deb-src http://www.debian-multimedia.org sid main
deb http://www.debian-multimedia.org experimental main
deb-src http://www.debian-multimedia.org experimental main
A recommended /etc/apt/apt.conf
To upgrade to Debian SID:
apt-get update; apt-get dist-upgrade
If you are running VDPAU, install Nvidia proprietary drivers:
apt-get install nvidia-kernel; module-assistant a-i nvidia-kernel ; apt-get install nvidia-glx nvidia-libvdpau1-dev
Modify /etc/X11/xorg.conf and replace "nv" with "nvidia" in the driver section.
Then checkout Frei0r-plugins, MLT and Kdenlive from sources. You may find useful information here:
Question: I would like to add a new effect to Kdenlive. How to add the effect in MLT?
Answer: check-out Frei0r and MLT and read frei0r plugin code in MLT: /src/modules/frei0r . You can either add a new plugin to MLT or add the feature in Frei0r, which is already implemented in MLT. Other choices are also possible. Discuss this with us.
Question: Why should I join Kdenlive and not project Foo?
Answer: MLT is the future of video editing and it is already a standard on GNU/Linux platforms. Other frameworks are oriented towards displaying video, not editing it. With the separation of video libraries (FFmpeg codecs), video engine (MLT) and user interface (Kdenlive), you have a more secure framework. Furthermore, our community is very well organized to track bugs, make frequent releases and write documentation. We will still be there in 10 years. So if you add some code to FFmpeg, MLT or Kdenlive, be sure your time is not lost. If you need a specific feature, don't loose time working on a minor video tool. Kdenlive and MLT provide you the basic import/export and timeline. So that you can concentrate on the quality of your code.
As described in the manual https://userbase.kde.org/Kdenlive/Manual/Settings_Menu/Download_New_Titl... in the past you could download custom titles submitted by users. However, this feature has been broken since August, 2013.
Therefore the below information is at this point of historical interest only.
If you have created a nice custom title you can make it available to all Kdenlive users.
You can browse the list of existing templates and modify or create a new one. Once a the template is created on the website, it can be automatically installed by all Kdenlive users (requires Kdenlive >= 0.7.8) from the menu "Settings > Download New Title Templates...".
