Flowblade, the free open-source Linux video editing software, released new 2.24 version few days ago.

The new release of this multi-track non-linear video editor focused mostly on UX improvements, bug fixes and GTK 4 port, while there are also some new features.

First, the new version improved support for Compound Clips, the way to group multiple clips into a single container clip on the timeline, by adding 2 new ways to create it.

Previously, user may either select multiple clips (via Ctrl or Shift + click) and use right-click menu to create Compound Clips, or go to menu Project -> Create Container Clip -> From Current Sequence to use the entire current timeline/sequence.

In the new version, user may also select a timeline range (press I in timeline for start point, and O for the end) or use box selection method to create the container clips.

It also added new Auto Sync Trim Single Childs feature, so that child clips now follow the their parent clips to be trimmed automatically when trimming the parent clips, though there’s an option available in “Syncing” menu to toggle on/off the function.

The release also improved the Rotomask editor with new Box Select Move edit mode, allowing to move a selection of edit points as a group. And, the line color is now editable through a new color picker tool.

Moreover, new “Add Title” option is added to both “Project” menu and Media panel context menu, allowing to launch the titler dialog. And, the titler dialog added options to set the title name, and close the dialog automatically when clicking save.

Other changes include new Alt+J keyboard shortcut to mark selection range, new “Warning on Disk Cache Size” limit (4 GB and 8 GB), warn if estimated size exceeds 60% of the available disk space, as well as following changes:

• Allow moving audio master meter position to bottom row.
• Add ‘To Marks In’ and ‘To Marks Out’ buttons to player button panel.
• Fix Audio Sync Split undo bug.
• Add progress bar dialog for “Duplicate sequence…” action.
• Make keyframe info bigger and move it to the left side in keyframe editors.
• Fix ripple trim undo.
• Clear box move data on undo/redo.
• And various other minor improvements and fixes.

As mentioned, the release also includes some GTK4 port, such as new keyboard shortcut framework with per widget shortcuts, and more. See the RELEASE NOTE for details.
