It’s not officially announced in its website at the moment of writing, but the source tarball is out for those who want to compile by themselves. And, the Flatpak package has been updated for most Linux users.

As you may know, Kdenlive 24.12 introduced Built-in Effects option in settings, which will automatically add the Flip and Transform effects to the video part, and the Volume effect to the audio part by when you dragging a clip into the timeline.

This is a step by step guide shows how to compile the Kdenlive video editor 24.12.0 from source tarball in Ubuntu 24.10.

OpenShot released version 3.2.0 a few days ago with great performance improvements.

OpenShot is a free open-source Qt-based video editor works on Linux, Windows, and macOS. Due to its beginner friendly menu options, built-in title templates, and animated titles (Blender powered), I prefer it over Kdenlive and Shotcut.

However, the video editor was sluggish, froze frequently, and slow for video preview playback every time after made changes. It made me crazy quite often, so I turned to learn using Kdenlive for basic editing.

In OpenShot 3.2.0, the video editor has significant performance enhancements. It’s now running smoothly out-of-the-box in my Ubuntu 24.04 laptop!

For those who prefer the native .deb app packages, here’s new unofficial PPA for installing the most recent Kdenlive video editor 24.08.3 in Ubuntu 24.04 and 24.12.0 in Ubuntu 24.10.

Since version 24.02, the Kdenlive video editor is finally ported to Qt6 plus KDE Frameworks 6, which brings big performance improvements, but also a few regressions.

Due to this change, the developer team discontinued the official Kdenlive PPA, since KF6 is NOT yet made into Ubuntu repositories.

The official packages are now only Flatpak and AppImage, that run in sandbox. For those who prefer the .deb package format, here’s the new unofficial PPA for choice.

Kdenlive video editor released new 24.02.0 version this Monday!

The new release now takes use of Qt6 and KDE Frameworks 6 for its user interface. The port gets overall experience and better Wayland support for Linux users. And, it now runs natively on DirectX, Metal, and Vulkan respectively on Windows, MacOS, and Linux with substantial performance boost.

However, due to this change, the developer team discontinued supporting for the official PPA that contains the native .deb package for Ubuntu and Linux Mint. Now, it supports only AppImage & Flatpak for Linux.

Other downsides due to switched to Qt6 and KDE Frameworks 6 include:

  • Themes and icons not applied properly in Windows and Linux AppImage.
  • Temporarily removed audio recording feature.
  • Text not properly displays in clips in the timeline for Linux Wayland.
