This commit updates the _get_effective_crop_rect_for_frame method to improve the calculation of the crop rectangle in rotated frame coordinates, incorporating tracking follow functionality. It ensures that the crop rectangle is accurately centered on the interpolated tracking position when motion tracking is enabled. Additionally, comments have been clarified to reflect the use of the effective crop, enhancing code readability and maintainability.
This commit updates the VideoEditor class to store and manage tracking points in rotated frame coordinates, improving accuracy in overlay rendering and user interactions. It introduces a new method for mapping rotated coordinates to screen space and modifies existing methods to ensure consistent handling of coordinates throughout the editing process. These changes enhance the overall functionality and user experience when working with motion tracking in video editing.
This commit modifies the cropping functionality to apply transformations in rotated frame coordinates, ensuring accurate cropping after rotation. It introduces a new method for mapping screen coordinates back to rotated frame coordinates, enhancing the overall cropping experience. Additionally, debug statements are added for better tracking of crop operations, improving the debugging process during development.
This commit enhances the _map_original_to_screen and _map_screen_to_original methods by clarifying the calculations for zoom and rotation. It introduces new variables for better readability and ensures accurate mapping of coordinates, including adjustments for display offsets. The changes streamline the processing of frame dimensions and improve the overall functionality of the video editing experience.
This commit introduces motion tracking capabilities, allowing users to add and remove tracking points on video frames. The tracking state is managed with new attributes, and the crop functionality is enhanced to follow the tracked motion. Additionally, the user interface is updated to reflect the tracking status, and keyboard shortcuts are added for toggling tracking and clearing points. This feature improves the editing experience by enabling dynamic cropping based on motion analysis.
This commit introduces the Cv2BufferedCap class, which provides a buffered wrapper around cv2.VideoCapture. It implements frame caching with LRU eviction to optimize frame retrieval and reduce latency during video playback. The VideoEditor class has been updated to utilize this new class, enhancing performance and simplifying frame management. Unused frame cache methods have been removed to streamline the codebase.
