Inputs:

• image: Input image(s)
• frames: Number of output frames (2-120)
• start_crop_ratio: Initial crop ratio (0.1-1.0)
• middle_crop_ratio: Middle point crop ratio (0.1-1.0)
• end_crop_ratio: Final crop ratio (0.1-1.0)
• middle_frame: Frame where middle ratio is reached
• input_mode: Processing mode selection

Outputs:

• frames: Processed image sequence
• masks: Corresponding crop masks
