Revolutionary green screen-less keying technology
Kapwing's background removal function is built based on computer vision algorithms, recognizing the subject and background elements in the frame through semantic segmentation technology. Compared with traditional green screen technology, its breakthrough is that it does not require any special shooting conditions and can directly process material recorded in ordinary environments.
In terms of technical implementation, the system analyzes the depth information, color contrast and edge features of the video frames to build a 3D model of the subject outline. Users can finely adjust the edge processing effect through the threshold slider and preview the keying quality in real time. Advanced options also provide professional parameters such as edge feathering and shadow retention to ensure natural compositing effects.
Actual tests have shown that the function's recognition accuracy for people, products and other clear subjects exceeds 90%. It is especially valuable for e-commerce application scenarios, where merchants don't need professional studio equipment, and can easily replace the video of products shot with cell phones with branded virtual backgrounds after processing, which significantly reduces the cost of producing product display videos.
