Kdenlive 16.04.0

Wednesday, 20 April 2016

Kdenlive 16.04 is a major release, bringing you the result of several months of work with the feedback of several professional video editors. Many usability and stability issues were addressed as well as dozens of new features.

Here is a quick list of some of the features that were added:

Monitor

Configurable monitor overlay: you can now display timecode and safe zones in monitors
Audio waveform overlay: Clip monitor now displays a preview of the audio, making it easier to seek to the wanted place
Markers can now be edited directly on the monitor display
Effects can be dropped directly on the monitor
Live display of playback fps
New audio level meter in monitor toolbar

Timeline

Faster audio thumbnails: rewritten, they are now created 7x faster, drawing 5x faster
Editing: added "Match Frame" feature
Transitions: implement transition parameters - Cairo Blend transitions now supports opacity and alpha operation and is keyframable

Effects

"Split view " to display a split view of timeline's current clip with and without effect to compare
Speed effect now uses MLT's new TimeWarp producer, so sound is now working with speed effect
Support for curves in some effect parameters (volume, etc)

Project Bin

Metadata: clip metadata is back, giving you details about your audio / picture files
Improved automatic profile: if enabled, Kdenlive automatically proposes to switch profile to match that of the first added clip
Generators: you can easily create noise, color bar and counter clips

Library

New Library widget allowing to save parts of the current timeline to share them between several projects

Titler

Fix longstanding (since the 12.x series) crash affecting titles with transitions
Allow adjusting letter and line spacing
Text shadow
Gradient fill for text and rectangles

DVD Wizard

Alignment grid for menus

Export

Rendering widget rewritten to be less frightening
New parameter to decide if you prefer faster encoding or smaller file size

General

New "Favorite Effects" widget, allowing quick access to your preferred effects
Many small UI and workflow improvments and bug fixes
