What is a "DV documentary"?

This is very simple, it is a documentary filmed with DV.

Documentary is a film and television art form that takes real life as the creative material, real people and real events as the performance objects, and artistically processes and displays them. Its essence is to show the truth and use it to arouse people's thinking. The birth of film began with the creation of documentary. 1895 French Louis Lumiere's experimental films, such as the gate of the factory, the train entering the station and the baby's lunch, all belong to the nature of documentaries. China documentary shooting began at the end of 19 and the beginning of the 20th century. The first one is Dingjun Mountain at 1905. Some of the earliest scenes, including the social scene in the late Qing Dynasty, the scene of Eight-Nation Alliance's invasion of China, and the historical figure Li Hongzhang, were all taken by foreign photographers. Documentaries can be divided into film documentaries and TV documentaries.
