Kdenlive 25.04.0 released
Monday, 28 April 2025  |  Jean-Baptiste Mardelle

#Release
We are proud to announce the release of Kdenlive 25.04.0. Here are some highlights of this major release:

Object segmentation
A new plugin based on the SAM2 model now allows you to create object masks to remove the background of your videos or apply an effect only to an object. All processing is done locally.

Improved audio waveforms in timeline.
A nice refactoring was done by Etienne André to make the audio thumbnails faster and more precise.

OpentimelineIO import/export
Darby Johnston rewrote our OpentimelineIO import and export function using the C++ library. Now you can exchange projects with other editing applications that support this open source file format. Please note that effects, filters, and transitions are not exported as each application uses its own standard.

Workflow improvements
Among the many small improvements, here are some of the noteworthy changes:

The duration of multiple adjacent clips can be changed in one operation
Allow vertical zooming of audio waveforms
Fixed proxy clips workflow for videos with an alpha channel
Added Shift+Click to expand/collapse all effects in the stack
It is now easier to find out which monitor is active as the time code widget now uses a different color
Added a search feature to the project notes, and made standard search shortcut work on all widgets
Fixed UI translations not appearing correctly despite being translated
Kdenlive now remembers the last used LUT files when doing color correction, making it easier to access them
Fixed Render widget hidden behind main window on Mac
Many other improvements made it into this release, and we closed more than 30 reported bugs. Please see the change log below for details.

Last minute fixes
Some last minute fixes have been included in our binaries:

Fixed a corruption when copying and pasting sequence clips to another project
Improved the Title Editor's text outline to follow the font curves more closely
Fixed an application freeze when trying to extract the last clip in a track
Made the Auto Save feature less aggressive by increasing the time intervals and fine tuning the triggers in order to prevent a severe lag in large projects
