How are public classes usually filmed? How much will it cost?

Video open class shooting is mainly for ordinary school students to watch lectures by famous university teachers. Its shooting method is three shots, and then the service content is to make shooting plan, venue lighting layout, lecturer makeup, shooting, video editing and packaging, and making the opening and closing credits. The cost is almost 16000 per day. If you want to shoot, go and see Beijing Desheng system, which is quite good. This is also recommended by my friend.
