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 0.9.10, released in September 2014, see announcement and info page.

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.

Getting ready for Kdenlive 0.8.2

The release of Kdenlive 0.8.2 was slighlty delayed due to the discovery of a blocking issue that required last minute changes in MLT and Kdenlive.

I want to make sure that those changes don't cause regressions, so the idea is to ask users to test the latest Kdenlive development version (available for Ubuntu users on sunab's experimental repository). I am especially concerned about problems occuring when opening old Kdenlive project files.

Once we have some feedback and manage to fix a few remaining issues, we will release Kdenlive 0.8.2, which should hopefully happen around the 13th of august.

We are now in string freeze, so if you are interested to help translating Kdenlive in your language, get involved.

More informations about the changes in the soon to be released 0.8.2 version can be found on the Kdenlive 0.8.2 information page.

After that release, we will be moving to KDE's infrastructure to be part of KDE multimedia, and work on the refactoring branch to clean up the code and make it easier to understand / maintain / contribute.

Feature of the week in Kdenlive: backups

While working hard in Randa, I implemented a feature that will make everyone happy: automatic backup of your project file!

We had a few reports on the forum of broken project files that were not recoverable. This is not a frequent issue, but losing all the work you have done on a video editing project is not fun! So after a short discussion with the Kdenlive team, here it is!

With this feature, every time you save your project file, instead of overwriting the existing version, it will create a dated backup of the previous version. In the Project menu, you will now have an Open Backup File entry that will bring up the dialog pictured here.

In the backup dialog, you see a list of all backuped versions of your project file with a nice screenshot of the timeline at the time the backup was made. You can then open any of the backup file to recover a previous version.

This is in svn and will be part of the next Kdenlive release.

A big thank you to all the people who made the Randa Sprint possible and so enjoyable!

We’re in Randa!

At the moment nearly the whole Kdenlive team is hacking in Randa, Switzerland, at the KDE Sprint 2011. Don’t believe it? Here is the proof:

(From left to right, ttill, xzhayon, j-b-m, Granjow.) So, as you can see, we are totally busy coding and writing the manual. The main activities are:

  • Big refactoring which will improve our code base in terms of maintainability and (for new coders) readability. We created a new branch for the refactoring. When refactoring is complete, we should also be able to write some automated tests.
  • User manual; we are now definitely moving to KDE Userbase which is based on MediaWiki (you all know this from Wikipedia). It will also simplify translation. The first version of the Quickstart tutorial is already online.
  • GIT will be our new version control system at KDE multimedia.

That’s it so far! We’ll go back coding now.

Randa KDE sprint


Several Kdenlive developers will meet in the next days in Randa (which will host a big KDE sprint) to exchange ideas and discuss about Kdenlive's evolution. I hope that we will come up with some great ideas, we will keep you informed!

Widget layouts in kdenlive

You may probably have noticed that some additional widgets have been added to kdenlive recently. And you probably do not want your kdenlive to look like that:

(Notice that this is on a 1680×1050 screen. You absolutely don't want kdenlive to look like that on an even smaller screen.)
