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 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.

Kdenlive 0.9 released


Kdenlive 0.9 has just been released. We encourage all users to upgrade to this new version that fixes many small issues and should improve the overall user experience. Some of the new features include:

Improved effects workflow

The effect stack was rewritten to allow adjusting parameters for several effects in one go. Effects can also be grouped, groups can be saved and effects or groups can be dragged and dropped onto another clip

Automatic audio alignment

If you have been working on a scene with several camcorders, Kdenlive can now automatically align the clips in timeline using the audio.

Easy import of online resources

Kdenlive now has an online resource browser that allows you to easily preview and import audio, graphic and video resources from archive.org, freesound audio library and open clip art.

Usability improvements

Many small improvements and bugfixes should make your use of Kdenlive nicer and smoother, for examples:

  • Recording can now be monitored through the audio and color scopes, audio normalization can analyse audio for better results
  • Allow audio only recording
  • Clips can be sorted by date
  • New effects from MLT / frei0r: video stabilizers, IIR Blur, etc
  • Offline editing (Backup the project with proxy clips only to work on less powerful computers)
  • See a more complete changelog on our Kdenlive 0.9 info page

Get it!

The Kdenlive 0.9 source tarball can be downloaded from the KDE servers: download link.
Binary packages will be announced in our download page

The future

A big thank you to all the people that contributed in one way or another to improve this new version. Some bugfix 0.9.x releases will be made when necessary, but in the background we are working (well mostly Till) on a refactoring to cleanup the code and hope to reach the 1.0 milestone by the end of the year, thanks to the fantastic success of our fundraising campaign.

As usual, users are welcome to join our forums and bugtracker to report problems.


Improving effects workflow in Kdenlive

First, I should say a big thank you to all the people that helped make our Fundraising campaign so successful, but more infos about that will come in the next days. It is anyways really motivating to see that you are supporting us!

On my side, I have been working on a rewrite of the Kdenlive's effect stack. This work has just been merged into master git, so users of sunab's experimental PPA will get it in the next update, probably in 1-2 days.

The highlights are:

  • Adjust parameters for several effects without switching between effects
  • Drag & drop effects from the effect stack to another clip or track
  • Create effect groups that can be saved or dropped to easily pass effects to another clip or track

I tested the new features for some time now, there are probably a few bugs, but it is really worth it in my opinion, So I am waiting for your feedback & bug reports. And here is a small video demonstrating the new effect stack (video link):

Kdenlive fundraising campaign

With an ever growing code base Kdenlive has become harder and harder to maintain and to develop further. To drastically improve this situation we worked out a plan to refactor Kdenlive's code at the KDE developer sprint in Randa last summer. However since we are all short of time you haven't seen any of promised work done yet.

But now you have the possibility to help. I will be able to work on Kdenlive full time in May and June. To do so however I need an income. We therefore created a funding campaign on IndieGoGo. While you might not be interested in the code improvements itself sure you are in the resulting benefits: When the code is easy to maintain less bugs occur. Developers have more time to work on new features. It's easier to attract new developers which accelerates progress.

So go ahead and donate to our Kdenlive fundraising campaign

Kdenlive - latest developments

Here is a quick info on the features introduced in Kdenlive git since the release of Kdenlive 0.8.2.1.

Audio Recording


Capture through MLT's avformat producer now supports audio only capture. It even works while playing the timeline, so that you can record a comment while viewing your project. You can see a screenshot of the updated capture widget.

Clip Jobs


A generic job framework was introduced, based on the proxy clip feature. Here are some of the consequences:

  • It means first that the proxy clip got some UI improvements. Progress of the proxy job is now shown in a small progress bar at the bottom of the clip thumbnail, so that the operation is not distrubing your workflow.
  • Then, the new job framework is intended to make it easier to introduce new operations on project clip, for example a new Extract zone feature allows to cut parts of a clip without re-encoding (using FFmpeg codec copy feature).
  • Another related feature is the introduction of clip analysis for some effects. For now, it is available in the "Sox Gain" effect that now has a "Normalize" button. This will trigger an analysis of the clip to find the best gain correction.
  • More jobs are expected to appear, for example the Stabilize feature could be ported to it.


Online services integration


A new Online Resource widget made its appearance, and allows you to easily browse and download resources from the web. Currently, two services are implemented:

  • The excellent Freesound free audio library allows you to search and import audio clips in a few clicks.
  • The great Open Clip Art library allows you to import graphic files.

That's all for now, but I am quite happy with those newly introduces features, after all those months spent fixing bugs for the last release.

Interested testers can get the current git version from sunab's experimental PPA, or through the Kdenlive Build script.

Next, we have to work on the refactoring suff to improve our existing code, make it more modular and easier to contribute.

Thanks for reading, Jean-Baptiste Mardelle

Kdenlive 0.8.2.1 released

The 0.8.2.1 release of the Kdenlive video editor is now available. This is a bugfix release that solves several startup crashes and other important problems in the 0.8.2 version.

All users should upgrade to that new version that provides an improved stability as well as some threading optimisations that should make some operations slighlty faster.

Kdenlive bugfix release

Kdenlive 0.8.2 - released 2 weeks ago - had several annoying issues that were quickly reported, including startup crash on some systems. We did our best to fix these issues and are almost ready to launch a 0.8.2.1 bugfix release.

So if you experienced serious problems with the 0.8.2 version and want to help, we would like you to test our latest development version so that we can make sure the biggest problems are solved for a bugfix release.

If you are on Ubuntu, you can use the Sunab experimental PPA that will bring you the latest MLT and Kdenlive (please note that currently it is an english only release, translations should be back in a few days).

Other users can try the latest code using the Kdenlive build script that was updated to use our new git repository.

You will find detailed infos on the current issues on the 0.8.2.1 info page.

For the Kdenlive team, Jean-Baptiste Mardelle

Welcome to KDE Git, Kdenlive!

0.8.2 release marked the time to complete our switch to KDE development infrastructure started in Randa a few months ago. On November 8th our old Subversion repository on SourceForge was discontinued, and we moved on to our new, shiny KDE Git repository!
There are at least a couple of differences you - especially developers and translators - should be informed about.

  • Development workflow. Git offers many features that Subversion doesn't. Thus, we're defining a workflow to guide development which will hopefully improve stability in next releases. We'll have it documented quite soon.
  • Translations. Kdenlive translations are not stored anymore into its sources: they're now in KDE l10n module. Should you want to work on them, you'll have to get in touch with your translation team. Also - this is mostly for packagers -, we'll write a script to automatically fetch translations and populate appropriate directories for tarball releasing. Again, our documentation will be properly updated.

As a KDE project, Kdenlive is now open to a wide developer ecosystem. Just as we don't want to loose any active developer (get a KDE Git account!), we would be happy to welcome new members, occasional contributors and new translators to our team, maybe among those already committed to KDE. The road to Kdenlive is much shorter now, don't play hard to get! ;)

Kdenlive 0.8.2 is released

We are proud to announce the immediate release of Kdenlive 0.8.2. We encourage all users to upgrade.

For this release, we did put a lot of energy into bug fixing and stability (more than 140 issues solved) to bring you a better editing experience. We have solved a lot of project corruption issues, and the introduction of the automatic backup feature means you should hopefully enjoy Kdenlive better than ever!

Among the features improvements, the proxy clips (clips replacing the original ones when editing a format that is too slow to edit, for example AVCHD) should work fine now, HDMI capture should also be improved (feedback welcome) and some GUI multi threading should make operations a bit smoother.

As usual, we also benefit from the latest improvements in MLT, a new version (0.7.6) was released today that improves stability and fixes important issues for users of non english locale.

We are also getting closer to the KDE community, and the first step was to start a documentation effort, which means Kdenlive is now distributed with a "Quick Start Guide" that should show you the basic steps to start working in Kdenlive. This help is also available and editable online on the KDE Userbase Wiki.

For a detailed list of changes, see our Kdenlive 0.8.2 information page.

And since we want Kdenlive everywhere, you can now also follow us on Facebook, Twitter, identi.ca.

A big thank you to all the developers, translators and users who helped to make this great release.

Source code can be downloaded from our sourceforge page, and packages will be announced as usual on our download page when available.

Support can be found in our forums and issues reported on our bugtracker.
