The nested timeline feature will allow you to open several timeline tabs. Each tab contains a separate timeline, all of them share the same project bin and will be saved inside the same project file. You will then be able to insert (or “nest”) one timeline within another, and it will act as a single clip. However, changing a sequence in a nested timeline will automatically update it in the container timelines. You might want to integrate, for example, a complex “Final credits” compositing sequence with 10 tracks at the end of your project. You could do this in a timeline tab and then insert that timeline as a single clip into your main project, allowing for a much cleaner workflow.

Currently, if you want to tweak some basic parameters like the brightness or contrast of a clip, you need to go through several steps: First, you have to search through the effects list to find the one you need. Then you have to add it to the clip itself, and, finally, you have to adjust the parameters.

This is quite cumbersome for what is simple, everyday adjustments. To make your workflow much more fluid, we will introduce a new effects panel that gives you direct access to these parameters, allowing you to quickly and easily adjust levels, crop, transform and, for audio clips, volume, and pan.

Your donation will help us overhaul the code and improve Kdenlive’s general responsiveness. An in depth (and time-consuming) refactorization will help make Kdenlive snappier and more pleasurable to use overall.

We will be able to improve video and audio playback on the timeline, both at normal and slow speeds. This will help you when reviewing and tweaking clips, cuts, effects and transitions, making these tasks much easier, less prone to errors and more fluid.

Supporting us will also contribute to the harmonization of the rendering pipeline, which will positively affect proxy clips and timeline previews, as well as the final rendering of your work, making the encoding, previews and renders of your project faster, stabler and more reliable.
