What kdenlive 18.12 will bring you

A new refactored timeline

Split Audio/Video

We have changed the way timeline tracks work. Each track is now either audio or video, and will only accept audio and video clips respectively.

When dragging an AV clip from the project bin in timeline, the clip will be automatically split, the video part going on an audio track, and the video part on an audio track.

Improvements

Resizable tracks
configurable thumbnails for each track
Clip name always displayed when scrolling
Individual clips can now be disabled (still in timeline but with no audio and no video - works for all clip types)
Faster timeline preview - with support for hardware accelerated encoding
Improved feedback on move/resize

Project Bin

Improve management of proxy clips (can now be deleted for each clip)

Monitors

Support multiple guide overlays

Titler

Added configurable visual guides

Effects and Compositions

You can now define preferred effects and compositions. These will appear in the timeline context menus and in the effect/composition baskets for easier access
When dragging a composition from the list into timeline, it will automatically adjust its duration (to fit the entire clip or the duration of a clip overla depending on the context)

Resources

Since a long time, Kdenlive allowed users to download extra user contributes resources from store.kde.org. These download options have now been moved to more logical places instead of the "Settings" menu. Title templates can be downloaded from the Titler dialog, Render profiles from the Render dialog, Luma compositions from the Composition list and Shortcut layouts from the Shortcuts dialog.
