(Green screen technology is no longer a secret. Likewise, there are plenty of people who innovate with this technology and sell it for cash. Prices are also high and low. So when it comes to cash, it's not just about selling technology. an option. I believe that when you watch the live broadcast, you must have seen such a live broadcast room, such as a blind date in Africa, or singing and dancing in Africa. The other is to directly have someone appear on the stage, and then demonstrate through a green screen to package the entire technology very well. In fact, it is the application of this technology.)
