Software Update: Kdenlive 21.08

Version 21.08 of Kdenlive has been released. Kdenlive, short for KDE Non-Linear Video Editor, is an advanced non-linear video editing program designed primarily for Linux, but also has versions for Windows, BSD, and macOS, although the latter is no longer actively developed. It uses several other open source projects, such as FFmpeg and the MLT video framework. The following changes and improvements have been made in this release:

Kdenlive 21.08 is out

Kdenlive 21.08 is out with an upgraded engine, bug fixes and many interface and usability improvements. Although the highlights are mostly under the hood we managed to add some nifty new features as well. This version now requires MLT7, which comes with a new time remapping feature and a more stable and concise code base. (MLT7 sets the foundation for long awaited features like GPU processing, multicore support and improved color management to name a few, all expected in MLT8.)

IMPORTANT

The Automask effect has been removed in MLT7 (along with many other legacy and buggy modules) but it will eventually be replaced with more powerful OpenCV tools. The Region module is also removed and it has been replaced with a new Effect Masking feature. Taking the opportunity of these changes we have also cleaned up the code base and removed old and unmaintained tools like the DVD Wizard (yes, some people still used it) and the Preview Compositing mode. We do not recommend to open old projects with Kdenlive 21.08 due to the aforementioned changes.

Performance

We continue with every release to improve performance and with this version the Jobs Processing code has been completely refactored fixing an interface lag/freeze when importing hundreds of files and hundreds of gigabytes at once. Also panning through the timeline has a more fluid and smoother experience due to recent changes.

Time Remapping (Speed ​​Ramps)

The new Time Remap feature allows to keyframe the speed of a clip.

Masking Effects

You may now apply effects to only affect specific regions of a clip by using masks. Do note that this is only the initial implementation so expect an improved workflow in the coming releases. For now the process involves 3 steps:

Interface and Usability Improvements

Move Guides with Spacer Tool
Easily moves Guides along with clips using the Spacer Tool by using the new Guides Locked option.

Raise widgets with shortcuts
Added ability to assign shortcuts to raise dock widgets.

Shortcuts for keyframe functions
Added ability to assign shortcuts to 3 keyframe functions: Add/Remove Keyframe, Go to next keyframe and Go to previous keyframe.

Same track transition improvements
Added additional options to the same track transitions: Duration, Reverse and Alignment.

Command Bar
The command bar allows to easily search for any action in Kdenlive like changing themes, adding effects, opening files and more. It can be accessed with the shortcut: Ctrl + Alt + i. (This feature requires KDE Frameworks lib version 5.83)

Copy value at cursor position to clipboard
In addition to the Copy Keyframes to clipboard, the new Copy value at cursor position to clipboard option allows to copy only the current value to a single keyframe.

New mapping modes and options when importing tracked data
Inverted Position and Offset Position are two new mapping modes for importing data from the motion tracker. Inverted position behaves like the current Position function but inverts the imported x and y values. Offset Position can be used for footage stabilization since it imports the difference between the first keyframe position (reference point) and the current keyframe position. Also new mapping locations were added: Top left, Center, Bottom right.

Rename guides from monitor
Clicking on a guide in the Project monitors allows to easily rename it.

Other fixes

• Titler: When editing a title clip there is a new Add as new title option.
• Add option to go to start if playback started on timeline end
• Fix audio thumbs for multistream clips
• Show markers thumbnails on hover in clip monitor
