Kdenlive 24.12 Added Multiple Subtitle Tracks & Removed Qt5 Support

Kdenlive, the popular Qt-based free open-source video editor, released new 24.12 version a few days ago.

The new release package was made available on December 14. KDE.org announced it within KDE Gear 24.12, though there’s still no official release note in kdenlive website at the moment of writing.

If you can’t wait for the official release note (the link is 404 not found at the moment), then here’s a quick overview about what’s new in this new video editor release.

Kdenlive Video Editor

Kdenlive 24.12 introduced multiple subtitle tracks support. User can now drag down a subtitle clip in the timeline to auto-create then move it to new tracks. And, “Manage Subtitles” dialog has been updated with options to manage subtitle tracks, while each track can have it own font styles.

The release also introduced Built-in Effects option, though disabled by default. With it enabled, it will always add the Flip and Transform effects to the video part, and the Volume effect to the audio part by default, when you dragging a clip into the timeline.

The video editor now has the ability to resizing multiple timeline items. Just select multiple items in timeline (shift+click) and double click on one of them. A dialog will be popped up, with the “Apply duration to all items” option allowing to resize them at the same time.

To speed up your workflow, there’s now a shortcut key Shift+Del to remove the selected clip from the Timeline and remove the gap. If the track is set to inactive the clips to the right of the extracted clip will not be moved to fill the gap.
