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.
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
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.
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 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.
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)
The Kdenlive 0.9 source tarball can be downloaded from the KDE servers: download link.
Binary packages will be announced in our download page
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.
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):
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.
Here is a quick info on the features introduced in Kdenlive git since the release of Kdenlive 0.8.2.1.
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.
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.
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.
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! ;)
