Add animated transition preview support in Kdenlive
Project Abstract
The goal of this project is to make Kdenlive's transition system more user-friendly and intuitive by adding animated previews. Currently, when users want to add a transition between clips, they have to rely on static icons or try the transition to see how it looks. This can be time-consuming and frustrating, especially when working with complex transitions.
The solution adds live animated previews directly in the transitions panel. When users browse through available transitions, they'll see a small animated preview showing exactly how each transition works. This means users can quickly understand how a transition will look in their project without having to apply it first.
Deliverables
- Live animated preview in the transition panel
- Python script for generating transition preview GIFs
- Code documentation and comments
Mentors
- Jean-Baptiste Mardelle ([email protected]) or contact through https://matrix.to/#/#kdenlive-dev:kde.org
Weekly Progress
Week 1 - 2: Environment Setup and Initial Structure
- Set up Kdenlive development environment
- Studied existing codebase structure
- Analyzed AssetListWidget and TransitionListWidget implementations
- Created initial project structure and files
- Implemented basic view switching mechanism in AssetListWidget
Week 3-4: Basic UI Implementation
- Implemented QListView integration alongside QTreeView
- Created basic TransitionIconDelegate class
- Added view mode toggle button to toolbar
