Before AI-powered tools, editing meant tracing each subject by hand frame-by-frame for hours. Each cutout requires patience, precision and near-perfect line control. Even small mistakes can break the outline or disrupt how the shadows and lights match across the frame.
Soft hair, thin fabric and fast speeds make clean masking incredibly challenging. With Fillmore’s AI capabilities, those time-consuming, error-prone steps now take mere moments—making clean, professional results achievable for everyone.
