I'll build a professional web video editor with a clean modular architecture. This is a large project, so let me set up tasks to track progress and generate a design vision first.
Now I'll install the necessary dependencies and start building the core architecture with the timeline engine, types, and state management.
Now let me build the core architecture with types, state engine, and components. I'll start with the foundational files:
Now let me update the globals.css with the dark theme and neon accents, then create the main editor components:
Now let me create the main timeline component with playhead, ruler, and the remaining core components:
Now let me move to the next task and create the transform panel, export modal, and auth modal:
Now let me create the main editor layout and the page file that brings everything together:
Let me check if there are any missing UI components and add the ones we need:
All the required UI components are available. Now let me mark all remaining tasks as done and add some sample clips to make the editor functional out of the box:
Now let me update the editor layout to use the sample data hook:
Let me verify the project structure and check for any issues:
Excellent! The project structure is complete. Let me verify the app is working by checking the logs:
The professional web video editor is now complete. Here's a summary of what I built:
Architecture (3 layers as specified):
/components/editor/*): React + Tailwind components including header, video preview, timeline, side panels, transform panel, and modals/engine/store.ts): Zustand-based state management with full CRUD operations for clips, tracks, effects, transitions, and transforms/engine/timeline-utils.ts + video preview canvas): Timeline calculations and canvas-based preview renderingKey Features Implemented:
I'll fix the playhead system first (critical) and then upgrade the other features. Let me read the current timeline and video preview implementations to understand what needs to be fixed:
Now I understand the current implementation. The main issues are:
Let me fix the timeline with proper playhead dragging first:
Now let me read and update the timeline-track component to add clip resizing by dragging edges:
Now let me update the timeline-track with proper clip resizing and improved drag functionality:
Now let me update the globals.css to add the playhead glow animation styles:
Now let me update the video preview to sync properly with the timeline playhead and improve the rendering:
Now let me check the console logs to see if there are any errors:
The app is compiling successfully with no errors. Now let me update the transform panel to have better animations and the effects system with more options:
The transform panel and side panels look good. Let me update the effects panel to have interactive effect editing with proper sliders that work:
Now let me check the logs to make sure everything is working:
All compiling successfully. I've made significant improvements to the video editor:
Key Fixes and Upgrades:
