Beijing show brings video works of 50 years into focus

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.
