I spent last week in rural Sussex DPing Ted Duran’s 30 minute action-comedy, The Gong Fu Connection. It was a great shoot with a real community atmosphere, excellent food and beautiful weather. I’ve just been looking through the rushes and I’m blown away by the amazing images that my Blackmagic Production Camera has produced. They are very filmic with an incredible amount of detail, even though we only shot in 1080P.
Not everything went to plan though. The aim was to capture the fights using fluid Steadicam photography, and since I hadn’t used a Blackmagic with Colin’s Steadicam Pilot before, he and I met up the weekend before to test the set-up.
The chief difficulty was that the rig’s built-in monitor accepts only a composite video input, while the Blackmagic outputs only an SDI signal. I searched online for a portable SDI to composite converter, but no such thing seemed to exist. I already had an SDI to HDMI converter, so the obvious solution was to buy an HDMI to composite converter. But the more links a chain has, the more opportunity for weakness.
I made the purchase and Colin sorted out power adapters so that both converters could run off the same battery as the Steadicam monitor. We tested it at my flat and it worked perfectly.
Flash-forward a week and we’re on set preparing the Steadicam for The Gong Fu Connection’s first martial arts sequence. All we’re getting on the Steadicam’s monitor are colour bars, which are output by the HDMI to composite converter when it’s receiving no input signal. The other converter, the SDI to HDMI one, has packed up.
Without a working monitor on the bottom of the rig, Colin can’t watch his step and frame the shot at the same time. The Steadicam is essentially useless.
There is a Canon C300 on set, being used for behind-the-scenes shooting. Although Ted and I are both keen to shoot the main film exclusively on the Blackmagic, to avoid severely disrupting the schedule we decide to shoot the day’s Steadicam material on the C300. (The C300 has SDI, HDMI and composite outputs. Blackmagic Design take note.)
At lunchtime I get on the wifi and see if I can order a replacement SDI to HDMI converter. The only one that can be delivered the next day (a Sunday) is the same model as the one that packed up. Having little choice, I order it. Amazingly it is indeed delivered on the Sunday. Nice one, Amazon.
Unfortunately it doesn’t work. I was at least hoping for the paltry month of service I got from the previous one. But no, this one is dead on arrival.
By a process of elimination we check that the converter is indeed the piece at fault. We swap cables and cameras and the results are the same.
We continue to shoot the Steadicam material on the C300.
But I have one last desperate idea to get the Blackmagic working on the rig.
On Monday morning I send our driver, Lucky, to the nearest Maplin. I’ve given him instructions to buy a small CCTV camera. When he gets back with it I have Colin attach it to the rig behind the Blackmagic, filming the Blackmagic’s screen. The CCTV camera outputs a composite signal directly to the Steadicam’s monitor.
Incredibly, this works. But it does mean enclosing the Blackmagic and the CCTV camera in black wrap to eliminate reflections on the former’s screen. Which means we can’t get to the iris controls, and we’re relying on the distances marked on the lens barrel to focus. And to make matters worse, the Steadicam Pilot can’t take the weight of a V-lock battery, so the Blackmagic must run off its short-lived internal battery. Between takes we have to plug it into a handheld V-lock to top up the charge.
After capturing two or three successful set-ups with this ludicrous rig, we decide it’s slowing us down too much. I finally abandon all hope of using the Blackmagic on the Steadicam.
For those interested in how the C300 and Blackmagic stack up against each other, the Canon has a sharper, more video look compared with the Blackmagic’s filmic images. The Canon also has more compression artefacts due to its lower bitrate. But they seem to cut together alright once graded.
The lack of an HDMI output on the Blackmagic has been the one thing that’s really caused me problems since buying the camera. I’d be tempted to go for a Kinefinity mod if it wasn’t so expensive…
Of course, the camera is still incredible value for money. Personally I think the only competitors in terms of image quality are the Reds. (The Alexa and film are in a whole other league.) But it is strange that Blackmagic Design claim to have built the camera for people working in the low budget world, but apparently didn’t consider that such people rarely have access to SDI monitors.
Stay tuned for more on The Gong Fu Connection shoot. There is still time to contribute to the project’s crowdfunding campaign over at Indiegogo.
