At the Using UGC masterclass, BBC Persian TV presenter Pooneh Ghoddoosi illustrated how "citizen journalism" has revolutionised the news coverage of Iran.
This film, which contains some disturbing images, was broadcast across the BBC. It shows four separate clips of an alleged hit-and-run incident, involving the Iranian security forces at the 2009 Ashoora Day demonstrations in Tehran.
Persian TV, with guidance from the UGC hub at TV Centre, went through a rigorous process, analysing the footage and making sure it was genuine before it was broadcast.
