Kdenlive 25.04.0 has been released and represents a significant update that introduces various enhancements, such as object segmentation, enhanced audio waveforms within the timeline, and the OpenTimelineIO import/export functionality. The plugin utilizing the SAM2 model enables users to generate object masks for the purpose of background removal or applying effects exclusively to a specific object. The OpenTimelineIO import/export function has been restructured by Darby Johnston utilizing the C++ library, facilitating the exchange of projects with other editing applications that are compatible with this open-source file format.

Improvements to the workflow include the ability to change the length of multiple clips at once, zooming in on audio waveforms, an easier way to work with proxy clips for videos with an alpha channel, and a new Shift+Click option to open or close all effects in the stack. The time code widget has been updated to feature a new color, enhancing the visibility of the active monitor. The project notes now include a search function, and Kdenlive now saves the last used LUT files for color correction.

Recent updates have been incorporated into the binaries, addressing issues such as corruption during the copying and pasting of sequence clips to different projects, enhancing the text outline functionality in the Title Editor, and adjusting the Auto Save feature for a more balanced approach. Kdenlive values the support of its community, and contributions are encouraged.

The comprehensive changelog details resolutions for various issues, including corrupted bin icons, application crashes, GPU whisper script, and additional enhancements. Contributions may be made by identifying and triaging bugs, translating Kdenlive into your language, promoting Kdenlive within your local community, or considering a donation to support the development of Kdenlive.

Kdenlive

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
