Kdenlive - a free and open-source video editor for GNU/Linux and FreeBSD

Kdenlive is an intuitive and powerful multi-track video editor, including most recent video technologies. Our software is completely free, as defined by the GNU foundation. Using Kdenlive is investing in a community driven project, which aims to establish relationships between people in order to built the best video tools.

Latest version is Kdenlive 0.9.8, released in may 2014, see announcement and info page.

Kdenlive at Randa

Back in 2011 among other things the foundations for a renewal of Kdenlive's code were laid in a small village in the Swiss alps. In August again some members of the Kdenlive team will attend the KDE developer sprint in Randa. We want to use the week to push new energy into Kdenlive and to discuss future plans. Major topics will be:

Kdenlive 0.9.8, the stable track

Dear kdenlive fans,

If you edit movies "for real", you probably don't use the development snapshots (do you?) and stick to the latest release, dating back from one year. Yet, our bugtracker didn't remain empty even with v0.9.6, so you may have been waiting for an upgrade... here it comes!

I like to Movit!

Dear Kdenlive users,

No news for one year, let's admit it was a low time for the project. But that's over: we are back, with renewed energy and cool new stuff to play with!

First of all, let's talk about the long waited GPU-accelerated effects, from Movit library.
Integrated for months in MLT, we had to activate GLSL backend in kdenlive to support this feature. Job done by Sesse (movit author) while preparing his brilliant demo at FOSDEM.

Moving Kdenlive's forum

The Kdenlive forums, that were usually hosted on kdenlive.org have moved!
Our forums are now hosted on KDE's forum website.

Existing posts have now been migrated to the new forum.

This move was decided because our kdenlive.org server could not handle the load anymore, and also because for a long time we wanted to tighten our links with the KDE community.

This will also help our developers to concentrate on Kdenlive's code, not on website maintenance.
So for now you can find the following Kdenlive resources on KDE's infrastructure:

We hope this will bring all users a better experience.

If you had an account on forum.kde.org and on kdenlive.org both registered to the same email address then your posts at kdenlive.org will have been merged into your forum.kde.org account. If you did not have an account on forum.kde.org then one will have been created for you on forum.kde.org with the same user name and email address as you had on forum.kde.org (Unless this user name was already in use at forum.kde.org. In this case a user will have been created with your kdenlive.org user name suffixed with _drupal). The new accounts created by the forum migration will need a new password before you can send to them. Request this at https://forum.kde.org/ucp.php?mode=sendpassword .

If anyone got the "_drupal" suffix and wants to change their username, just send a mail to the admins (forum-admin@kde.org).

Kdenlive: spring cleaning

Here are some news on what is happening with Kdenlive's video editor. Last year, we launched a successful IndieGoGo campaign to sponsor Till Theato's work on Kdenlive.

I have finally found time to start merging his great work so that we can clean up Kdenlive and move towards the future.

I will merge my work in the next days in Kdenlive's git master. This means that the master branch will become unusable for editing for a few months until we stabilize everything. So everyone using Kdenlive from git will need to switch to the v0.9 branch if they want to be able to do editing.

This work will bring in some exciting changes, like performance improvements and usability enhancements.
Since we will also improve the integration of the MLT framework in the process, we will also benefit from exciting new features like the high quality accelerated movit filters, and the new spline based animation feature.

I will try to post updates on a regular basis, so that people can also join the development.

Kdenlive 0.9.6 released

We are happy to announce the immediate release of Kdenlive 0.9.6.

This version fixes several bugs and crashes, including a very annoying bug that caused project files to seem corrupted. All users are strongly encouraged to upgrade.

You will find detailled infos about the changes in this release on our Kdenlive 0.9.6 info page.

The source code can be downloaded from the KDE servers, there are 2 available tarballs, since we decided to also distribute Kdenlive with its user manual:

Packages for your distributions should hopefully be available soon.
It is recommended to use the latest version of the MLT framework (0.8.8) to get the recent bugfixes and improvements.

As usual, a big thank you to all those who helped us make this release better by giving us feedback and investigating the bugs they found.
You can check the Kdenlive online manual and forums for documentation and help.

For the Kdenlive team,

Jean-Baptiste Mardelle

Kdenlive 0.9.4 released

We are finally releasing version 0.9.4 of the Kdenlive video editor after several delays.

This version fixes several bugs and crashes, all users are encouraged to upgrade. The source code can be downloaded from the KDE servers, packages for your distributions should hopefully be available soon. It is also recommended to use the latest version of the MLT framework (0.8.8) to get the recent bugfixes and improvements.

You will find detailled infos about the new features / fixes on our Kdenlive 0.9.4 info page.

Our efforts will now concentrate on merging the refactoring work started by Till Theato (as a result of our fundraising campain) , and cleaning the codebase to make it easier to evolve and integrate the future developments in the MLT video framework.

As usual, a big thank you to all those who helped us make this release better by giving us feedback and investigating the bugs they found.

Preparing for the new Kdenlive release

We are finally preparing the new Kdenlive release that should be out in 10 days (on the 19th of November). Many people are wondering what happened with our successful fundraising, so here is a first update: as it was clearly stated, the fundraising's goal was to clean up Kdenlive's base code. This will not produce immediate benefit for the user, but rather help us for future developments. The result of this refactoring has not yet been merged in Kdenlive's main tree, work will start after this release.

The last months were spent fixing important bugs that were discovered in Kdenlive 0.9.2 and also new issues that happened due to recent fixes in the video framework (MLT) that we use. Several small UI improvements and new features were also introduced as you will discover below. Users that want to help us can try the current development version (see our instructions for testing current development version) to give us feedback before the 19th of November release.

Here are some of the enhancements that will be available in next release:

Rewritten DVD Wizard

The DVD Wizard was mostly rewritten, now allowing 16:9 menus. It now also autodetects the format of your videos and proposes a trandcoding if it is necessary. In fact, you can now drop any video in the Wizard and just click transcode to get it in the correct DVD format.

DVD menus were also broken in the past versions, this should be fixed. While the menu creation remains very basic, you can now add a shadow to the menu's texts to make them look nicer.

Improved clip markers

The clip markers (comments that can be added and used for seeking in the clip) have been improved. You can now have several categories that show up in different colors. Markers can also now be imported and exported, and are compatible with Audacity's format.


Clip analysis feature

An exciting new feature is also introduced in this version: clip analysis. In short, we can have some MLT effects that analyse the clip and store the result for further use. The first usable cases are:
automatic scene detection: Kdenlive can now parse your clips to find the different scenes and add markers or cut the clip accordingly. The process is currently very slow but it's a start.
Improved motion tracking: Kdenlive can also now analyse an object's motion, and the result of this can be used as keyframes for a transition or an effect. For example, you can now have a title clip that follows an object (see small video demo below).
  
Of course, we also benefit from the fantastic work of developers working on FFmpeg, Frei0r and MLT (among others) that make all the video processing behind Kdenlive possible.

Don't hesitate to post feedback in our forums / bugtracker in the next 10 days so that we can make this release even better.
For the Kdenlive team, Jean-Baptiste Mardelle

Kdenlive 0.9.2 released

The 0.9.2 version of Kdenlive has been released, the source package is now available from the KDE servers.
This new release fixes the most important regressions found in the 0.9 version as well as a few other issues.

The crashes in the stop motion widget and composite transition are fixed, slideshows and firewire capture work again. For a full changelog, check our Kdenlive 0.9.2 info page.

Fixing bugs in Kdenlive 0.9

Ten days ago, I released the new 0.9 version of the Kdenlive video editor. Several annoying bugs were quickly detected and most of them are now fixed in git. so I am going to release Kdenlive 0.9.1 soon (hopefully tonight).

The fixes include:

  • Fix freeze when reloading previously missing clip
  • Fade effects lost when moving / resizing clip
  • Undoing change in clip crop start breaking clip
  • Make disabling of track effects possible
  • Fix slideshow clips not working
  • Fix crash on composite transition
  • Fix crash when opening stop motion widget
  • Fix rendering of projects created in another locale

For ubuntu users, these fixes are already available in the sunab's kdenlive-svn PPA, so if you want to give it a try before the official release and give some feedback, that would be great.
