What should I do if the background image is scratched when shooting a character video? # Post-photography Technology # Photography

Choose the key background when shooting, that is, green screen or blue screen. Generally, green screens are used more. After lighting the green background cloth, you can shoot in the indoor shed. When walking on the road, find a green keyboard player to move with people, and be careful not to enter the picture of the surrounding environment. After shooting, you can import post-processing software, mobile phones can use smart shadows, and computers can use audio and video. I personally use these two. Remove the green color with the eyedropper tool, and this layer will become transparent. Then add the background material you need to overlay and render it. If you want to be simple, you can download polar shooting software, which has real-time matting shooting function, which is more convenient than later. You can pick while shooting, just double-click the unwanted tone part in the picture, as long as the tone area will automatically disappear, become transparent, and import the album material. After shooting, I mean the matting and rendering are done together.
