The UK's third BritDoc documentary festival wrapped on Friday (July 25) with James Marsh's Man On Wire continuing its festival awards spree by winning the British Feature Film Documentary Prize.

Jerry Rothwell's Heavy Load - a film about a punk band with learning difficulties that was pitched at BritDoc in 2006 - picked up the audience prize.

The Solitary Life Of Cranes was the unanimous winner of the Four Docs Shorts Competition. The film, which explores the invisible life of a city as seen through the eyes of crane drivers, was funded by the Channel 4 British Documentary Film Foundation, which runs BritDoc. As part of the prize Four Docs presented director Eva Weber with a state-of-the art HD camera.

Julie Moggan picked up the prize for best pitch - worth $2,000 (£1,000) - at BritDoc's Big Pitch forum. Moggan's project Guilty Pleasure explores the global Mills & Boon romance fiction phenomenon.

Over 950 delegates attended the festival's third edition, held at Oxford's Keble College. Guests included Nick Broomfield, Sophie Fiennes, Gael Garcia Bernal, Michael Nyman, and Larry Charles - who ended the event with a packed interview session during which he screened clips from his forthcoming feature doc Religulous .

'People are really beginning to enjoy the opportunities here,' said BritDoc director Beadie Finzi. 'We try to assemble the key 40-50 people that all the film-makers need to know.'

Music and humour in documentary were the themes of this yeat's event, with Larry Charles, The Yes Men, Fahrenheit 9/11 editor Kurt Engfehr and Where In The World Is Osama Bin Laden writer-producer Jeremy Chilnick taking place in a lively panel discussion exploring the place of comedy in the form. 'When I was a kid documentary was like medicine,' Charles said.

Talking points at BritDoc included the opportunities offered by multimedia platforms and the rise of funding and outreach opportunities in the social change sector. To match social purpose projects with potential partners BritDoc this year held the inaugural Good Pitch forum for socially conscious films.

Organised by The Channel 4 British Documentary Film Foundation, Britdoc's sponsors including Channel 4, More4, the UK Film Council, Skillset, Suso, Screen South, JVC and Molinare.
