This commit refines the point transformation process in the VideoEditor class by ensuring coordinates are converted to floats and validating their positions relative to the crop area. It also updates the right-click event handling to accurately convert display coordinates to original frame coordinates, allowing for better interaction with tracking points. Additionally, the MotionTracker class is modified to set a default zoom center based on the crop rect if none is provided, improving the tracking functionality.
This commit introduces a new MotionTracker class for handling motion tracking during video editing. The VideoEditor class has been updated to integrate motion tracking features, including adding and removing tracking points, interpolating positions, and applying tracking offsets during cropping. The user can toggle motion tracking and clear tracking points via keyboard shortcuts. Additionally, the state management has been enhanced to save and load motion tracking data, improving the overall editing experience.
