Take a video with a camera, which involves a translucent figure. How to solve it with sound and shadow?

1. Shoot a video about plot action for girlfriend and boyfriend respectively, and the requirement is that the boyfriend's background is pure blue background (pure blue cloth, paper or wall, etc. ); The video of the girlfriend should set aside the corresponding position of the boyfriend;

2. Insert the video into the cover rail, adjust it to the screen size, use the "chroma key" to dynamically cut out the blue background of the video, and save the main video file for later use. The effect of dynamic matting with hue and shade chroma keys is very good. The following picture is made of chroma keys (because Baidu requires converting to gif format, it can only be displayed here, so the picture effect is poor, and it is good to play the video with a player):

3. Then create a new project, cover your girlfriend's video in the corresponding position of the video track, insert your boyfriend's video into the background and cut it out, and the overall position is the size. If you want to be translucent, you can add a translucent mask (you may want to use PS as a translucent mask) to synthesize the output video.

Many special effects of Hollywood blockbusters are produced by synthesizing the output videos of other scenes by using the principle of dynamic matting on blue background, but the software and equipment used are different.
