A stream of Blackmagic

CHINA: Chinese recording artist and actor, Luhan, recently staged a concert as part of his Luhan Reloaded: 2016 tour that was streamed on YY Inc owned mobile app, ME. The live stream followed the former EXO member in the lead-up to the concert, including rehearsals, as well as the main performance. To provide the coverage, four Ursa Mini 4K PL cameras and an Atem 1 M/E Production Studio 4K with the Atem 1 M/E Broadcast panel, all from Blackmagic Design, were implemented by the production company, Guangdong i-Mass Vision.

‘Concert lighting tend to be complex, bringing you both extreme brightness and darkness at the same time,’ explained Jiang Weizhong, director of Guangdong i-Mass Vision. ‘So we decided to use Blackmagic Design’s Ursa Mini 4K digital film cameras for its wide dynamic range.’

The Ursa Mini cameras were each equipped with the manufacturer’s Ursa Mini B4 Mount. All four of the cameras were set to film mode, which offers the device’s widest possible latitude.

‘Besides a much wider dynamic range, using the film camera for live production gives you another advantage because it includes an internal high quality recorder,’ said Mr Weizhong. ‘This means even in live production, you get film quality footage from each camera, great for postproduction, without hanging an external recorder for each camera.’

The signal from each camera was fed via SDI to a Blackmagic HDLink Pro for colour matching, before being sent to the Atem 1 M/E Production Studio 4K switcher, which was controlled by the broadcast panel. From there, the feed was taken to a live grading system, following which it was sent to ME’s live streaming system.

‘There are no white balance settings in digital film cameras as found in EFP cameras,’ noted Mr Weizhong. ‘However, using the HDLink Pro converters, we were able to apply a pre built LUT to each of the camera feeds for colour matching, which is a simpler solution.’
