This commit introduces keyboard controls for jumping to previous and next markers (cut start or end) in the VideoEditor class. The new functionality enhances user navigation during video editing, allowing for more efficient management of cut points. This addition improves the overall editing experience by providing quick access to key markers in the timeline.
This commit introduces a new method, seek_video_exact_frame, in the VideoEditor class, allowing users to seek video by exactly one frame, independent of the seek multiplier. The functionality is integrated with keyboard controls for navigating to the previous and next frames, enhancing precision in video editing. This addition improves user control and responsiveness during frame navigation.
This commit modifies the seek multiplier settings in the VideoEditor class, increasing the SEEK_MULTIPLIER_INCREMENT from 2.0 to 4.0 and expanding the MAX_SEEK_MULTIPLIER from 100.0 to 1000.0. These changes enhance the flexibility and responsiveness of the seeking functionality during video editing.
This commit adds functionality to the VideoEditor class to render tracking points from the previous and next frames with 50% alpha blending. Red circles indicate previous frame points, while green circles represent next frame points, improving the visual feedback during video editing. Additionally, the feedback message duration has been reduced for a more responsive user experience.
This commit updates the frame processing logic in the VideoEditor class to apply rotation before cropping, ensuring accurate handling of frames in rotated space. It introduces effective cropping that accommodates out-of-bounds scenarios by padding with black, improving the visual output during editing. Additionally, debug statements have been refined to provide clearer information on output dimensions and effective crop details, enhancing the overall user experience in video editing.
This commit introduces a new method, _get_display_params, in the VideoEditor class to centralize the calculation of display parameters, including effective crop dimensions, offsets, and scaling factors. The coordinate mapping methods have been updated to utilize these unified parameters, enhancing the accuracy of point mapping between original and screen coordinates during zoom and cropping operations. This refactor improves code readability and maintainability while ensuring a consistent user experience in video editing.
This commit updates the visibility width and height calculations in the VideoEditor class to use the minimum of the new dimensions and the window dimensions when cropping due to zoom. This change enhances the accuracy of the displayed area during zoom operations, ensuring that the canvas scaling is correctly applied and improving the overall user experience in video editing.
This commit updates the coordinate mapping methods in the VideoEditor class to utilize the effective crop dimensions more accurately. It clarifies the calculations for mapping points between rotated frame coordinates and screen coordinates, ensuring consistent behavior during zoom and cropping operations. Additionally, comments have been refined for better understanding of the effective crop application, enhancing code readability and maintainability.
This commit updates the cropping functionality in the VideoEditor class to use an effective crop rectangle derived from the current frame. It ensures that the crop is applied correctly within the bounds of the processed frame, enhancing the accuracy of cropping after rotation. Additionally, a visual outline of the effective crop is drawn on the canvas for debugging purposes, improving the user experience during video editing.
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.
