Kdenlive at Randa meetings - first report

We arrived here on wednesday, and started discussions about our plans in the train. Here is a short resume of what happened during these first days:

We decided to work on bug tracking during the first day, since the Kdenlive 15.08.1 release was imminent. We fixed quite a few bugs that will improve stability of the 15.08 branch.

The second important goal was to take advantage of having so many great people around us to improve Kdenlive. So we had contacts in these domains:

Mission statement:

We started the work on our "Mission Statement" to better define which users / jobs Kdenlive is designed for. This will help us to focus on important tasks for our target audience. We are in contact with people from the VDG (KDE's Visual Design Group) to get feedback on that process.

Ui design and workflow:



We had a session with people from the VDG (KDE's Visual Design Group) to review Kdenlive. We also had the chance of having a user of professional video software who had never seen Kdenlive so he was the perfect test subject for our UI review session. We wrote a wiki page on the ideas that came out of this. We encourage you to visit that page and give us feedback (a few issues were already reported on the bugtracker). As time permits, we will try to implement these ideas to improve the workflow.

Bugfixing:

There are a few issues/crashes in Kdenlive related to Qt5/KF5 bugs, and we made some contacts to get some help on this.

Next features:

We discussed some of the features we want to integrate for the 15.12 release, and other long term goals.

The feature we would like to integrate for the december release are: merge the animation feature from GSoC, same track transition (eg. overlapping 2 clips to crossfade), and a way to copy/paste between projects.

Preparing for Kdenlive 15.08

Kdenlive 15.08 will be released with KDE Applications 15.08. Beta version should be released next week.

This version is the result of a hard refactoring work to make Kdenlive's code cleaner and easier to maintain. While the refactoring effort is not finished and a lot of cleanup if still required, I am proud of the result that finally integrates some of the work from Till Theato and ideas gathered in our brainstorming from last year.

Of course, there will probably be a few regressions, but I am confident that they can be solved quickly. We will try to post some videos and blogs about the new features that you can expect in this release, Akademy 2015 will probably be a good time for that!

Hope to see some of you in Spain, and best regards from the Kdenlive team.

Kdenlive 15.04.0 released

The Kdenlive team is happy to announce the release of Kdenlive 15.04.0. While there are very few new features in this release, it is a huge step towards a bright future!


Kdenlive is now an official KDE application

This has several implications:

  • We fully benefit from KDE's infrastructure, which means less worries for the developpers.
  • We stick to KDE Applications release schedule, which means one bugfix release every month, one feature improved version every 4 months. That's a big change from the previous random release every year or so. This is possible because the KDE team takes care of the release, not our small dev team, so a big thank you to KDE.
  • We now use KDE's bugtacker at https://bugs.kde.org.
  • We benefit from KDE's build servers and team, which means that we might in the future have Mac OS and Windows versions without too much efforts from the dev team.
  • We can now be part of the Google Summer Of Code.
  • We have adopted the KDE Applications numbering scheme. From now on, Kdenlive versions will be numbered with Year.Month.Bugfix. That explains the 15.04.0 version.
  • Every KDE contributor can help us improve Kdenlive.

What changes right now for Kdenlive users

Most of the work for this release was porting the code to Qt5 and KDE Frameworks 5 (KF5). While users will not see direct benefit, this makes us ready for the next big steps. Changes in this version include:

  • Since we are now based on Qt5/KF5, you NEED KDE Frameworks 5 to run Kdenlive.
  • Fixed video stabilization
  • Auto save new projects
  • Download new render profile feature fixed

You can download the source code, binary packages for your distro should hopefully be prepared by distibution packagers.

What will change in the near future

While Kdenlive 15.04.0 is mostly a Qt5/KF5 port, we have many new features/improvements in preparation for the 15.08.0 release. Here are some of the features that we are currently working on:

  • Finally integrate some of Till Theato's work resulting from our Indiegogo campain. It took us 2.5 years but we are finally merging parts of the refactoring effort.
  • Use OpenGL for the video display, bringing back experimental GPU display and effects
  • Add effects to Project clips: for example, add color correction to the clip in the Project Bin. Every instance of the clip that is then used in timeline will have that color correction.
  • Cleaning the code to make it easier to understand.

That's it for today, I probably forgot many things but that might be an excuse to blog more often :).

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.
You can check the Kdenlive online manual and forums for documentation and help.

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.
