This caused some performance regressions in timeline playback and rendering. However, due to some bugs causing unwanted scaling in some situations, we defaulted to another transition for Kdenlive since 21.12.0. This used to be the default transition for track compositing in Kdenlive. Some long due fixes were also made to MLT’s qtblend transition. We do not have a definite ETA for the switch to Qt6 yet, but we currently expect it happen in the second half of 2023. There is still some work that needs to get done. However, this does not mean the version built against Qt6 will work as expected at this moment. This is the first step to ensure the transition from version 5 to version 6 of Qt and KDE Frameworks will be smooth. Qt6 and KDE Frameworks 6Īlso technically Kdenlive can now be built against Qt6 and a CI has been added to ensure this does not regress. It took a while to find and fix all these small issues, and the last one we were aware of was that the frei0r effects were missing.Beside the visible features already mentioned, the team worked a lot on cleaning up the code base to improve maintainability as well as preparing it for changes we expect in the near future such as nested timelines. The main job after was to adjust the so-called “blueprints”, and tweak some parts of the Kdenlive code to use the right file paths to find all the plugins. To build Kdenlive on macOS, we use KDE Craft, a meta-build system and package manager that we have already been using for some time for our Windows builds. Once the DBus issue was solved, there were only some small issues left to fix. When you use this flag, Kdenlive uses QLocalSocket and QLocalServer for communication instead of DBus. Vincent made it possible to build Kdenlive with the cmake flag -DNODBUS=ON. DBus is used for the communication between the render process and the application’s main window. If you follow the Kdenlive project closely, you will remember that in the first video cafe we talked about macOS and that a big blocker was that DBus caused trouble with the dmg packaging.
