In an era where people can make videos on their smartphones, what's the difference between a video taken by an artist and that by an untrained person?

An ongoing show at the art museum of the Central Academy of Fine Arts in Beijing may answer that question through the presentation of videos made over the past century.

Time Test: International Video Art Research Exhibition features more than 60 artists' video works from home and abroad and tries to present the development of video art since the 1960s.

It consists of two sections: One, from 1965 to 2015, which presents significant Western video works, and Chinese video art since the 1980s.

At the entrance of the exhibition space is placed Andy Warhol's Outer and Inner Space, a half-hour video that he shot about a celebrity woman talking to herself on TV. It's one of the first videos done by the American pop artist in 1965. He is considered among the world's pioneers in the visual art movement.

Then, there is Marina Abramovic's AAA-AAA, in which the "grandmother of performance art" is seen screaming with her partner Ulay.

The section on Western video art in the past 50 years shows about 20 influential artists' works, including Nam June Paik, who was the first artist to use a commercial portable camera to shoot videos, famous female artist Joan Jonas and some emerging artists continuing to push this kind of media forward.
