Versie 25.08 van Kdenlive is uitgekomen. Kdenlive, een afkorting voor KDE Non-Linear Video Editor, is een geavanceerd, niet-lineair videobewerkingsprogramma en wordt voornamelijk ontworpen voor Linux, maar er zijn ook downloads voor Windows en macOS. Het maakt gebruik van diverse andere opensourceprojecten, zoals FFmpeg en het MLT-videoframework. In deze uitgave zijn de volgende veranderingen en verbeteringen aangebracht:
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:
Added timecode widget with ability to drag to seek in the Titler,(Shift+drag for 1 frame, CTRL+drag for fast seek) Fix issues when resizing images would also moves them
Fix titler selection on create / resize object
Fixed an issue where the titler's panel width was consuming half the screen
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:
Subtitles and Text-To-Speech
Require shift + drag of a subtitle clip to create a new layer
Make the subtitle edit widget resizable to adapt to lower resolutions
Fix crash dropping media file on subtitle track
Subtitle code refacotring
Fix subtitle layer name width
Fix subtitles showing on the top layer rather than appearing in lower layers on project loading.
Fix Whisper TTS using Python 3.13
Whisper: disable translation when the Turbo model is selected
Fix Vosk TTS producing bad subtitles
Markers and Guides
Guides and Markers got a major overhaul this release to improve the project organization. Clicking a marker in the list now always selects it in the timeline
When adding a new marker, it’s automatically selected in the guides list
Selecting a guide in the timeline also highlights it in the guides list
New option to show thumbnails in the markers list dialog
Added a “Show markers for all clips in the project” toggle to diaplay markers in other sequences
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 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
Change Timecode color of active Monitor
Make sure playhead is always on top of indicators
Make transform effect monitor grid setting apply to both monitors
Fix keyframe in monitor not correctly reported on clip selection
Adjust monitor timecode for sequence clips with timecode offset
Monitor code cleanup
Video Processing
We've added work on rendering, encoding, decoding, and transcoding such as:
Decoding
Added Enable Hardware Decoding option in the Config Wizard in preparation for future hardware acceleration features
Rendering / Encoding
Added power management option to disable sleep while rendering and playing
Added Nvidia 10 bit x265 encoding
Added 10 bit export profiles in the render dialog (Do note that it will be converted to 8 bit when using compositing or non avfilter effects)
Fix image sequence render incorrectly reported as failed
Ensure audio checkbox is disabled if rendering to an image sequence
Fix possible locale issue on render in Mac/Windows
Added ability to show log files in render dialog Job Queue tab
Added option to keep log files in the render dialog options
Replace AV1 profile with faster SVT-AV1 and added preset option to control quality and speed
AddedSVT-AV1 to codecs which use CRF option
Fix canceling a render would leave Kdenlive in an unstable state
Warn when exiting Kdenlive when render jobs are running, allow to terminate all jobs
Update render dialog guides when sequence offset changes
Display timecode offset in render dialog
Under the hood
Reduced memory consumption of the background removal (SAM2) feature
Added more code tests to improve stability
Improved packaging in MacOS, Windows, Snaps and Flatpak
Cleanup plugins configuration page
Fix SAM2 use system packages hidden
Allow installing specific CUDA version for Whisper and SAM2
Fixes to undo/redo operations
OpentimelineIO (OTIO) fixes
Drop mediainfo dependency now that we can directly read timecode from MLT
Fixed platform specific issues:
MacOS: Allow opening project files by double click (3 year old bug)
Windows: Typewriter effect crash in Titler
AppImage: Fix missing / corrupted font making App unusable on Ubuntu 24.04
