The Kdenlive team is happy to announce the release of version 25.08.0 packed with over 300 commits and fixing more than 15 crashes. This release has no major shiny new features, just a ton of bug fixes and lots of polishing to give you a pleasant editing experience in the summer heat.

Interface and Usability

Mixer

Redesign of the audio mixer bringing levels with clearer visuals and thresholds. We also did some code refactoring and cleanup. This change fixes issues with HiDPI displays with fractional scaling.

Titler

This release the titler received some much needed love like improved SVG and image support with ability to move and resize items, added center resize with Shift + Drag, and renamed the Pattern tab to Templates and moved the templates dropdown to it:

Other fixes include:

• Save and restore the panel width on reopening
• Fix title thumbnail not updating in timeline after change

Scopes

Improved Scope styling by using system palettes for better theme integration as well as bug fixes in artifacts on high zoom level and paint modes. Compare the old styling on the left side with the new styling on the right:

Markers and Guides

Guides and Markers got a major overhaul this release to improve the project organization.

• Consistently use bookmark icon for guides/markers
• Improves Project Notes integration
• Render dialog now updates correctly when sequence offsets change
• Sequence timecode offsets now propagate to the timeline ruler, monitor, and guides list
• Guides are correctly adjusted when changing project profile to match a clip profile

Project Notes

Some highlights include: improve icons, automatically convert typed timecodes to links when pressing enter, fix pasting text with multiple lines, notes can create guides and markers directly, and the widget has improved icons and text handling

Monitors

• Add handle to rotate an item using the Transform effect in the monitor
• Fix rotoscoping shape not matching selection in monitor
• Fix monitor overlay for Obscure and Alpha Shape effects
• Fix Transform monitor tool resizing when rotated
• Fix pattern/lines overlay of the project monitor misaligning if clip changes while zoomed in
• Improved monitor snapping: added back snapping when resizing for non-rotated frames, snapping when moving a rotated frame, and added snapping support for all edges when moving instead of only top-left
