Shooting a live broadcast from Tokyo on a Canon 1D Mark IV – Al Jazeera's Matthew Allard tells how

Canon 1D Mark IV Live Cross on Aljazeera from Matthew Allard on Vimeo.

I have to do a lot of live crosses as part of my job. Whether they be via Bgan satellite terminal, the internet through Quicklink or through a SNG they all can present difficulties. Shooting live crosses in hotel rooms at night is a nightmare. My normal broadcast camera (Sony XDCAM HD) is not very good in low light. To be able to get enough light on the subject and make a very dark background not look like a black abyss is virtually impossible. With the introduction of DSLR cameras with great low light capabilities there finally is a tool that can help in these situations. The Canon 1D Mark IV shows almost no noise at high ISOs. By running 2000 ISO and using minimal lighting i was able to bring the background back to life.

So how did i do it? There is a lot of problems associated with getting a clean output out of a DSLR camera. What i managed to find out by experimenting is there is a way to get around this. But before you get too excited it does require some extra expensive equipment (I’m sure there may be a cheaper way). By taking a composite video output of the 1D and running it into a SONY XDCAM HD F70 player/recorder. From there I am able to take a firewire output from the same machine and it becomes a loop through DV device that i can use for Quicklink Live (the software Aljazeera uses for live transmission).

The camera does have to be in record mode for this to work. If the camera is in live view mode and not recording it will auto shut off after a few minutes. By turning off the display information you get a clean signal out of the camera minus the focus bars and red record dot. For the audio I had the choice of running a microphone straight into the F70 or looping it through the Zoom H4n. By doing either one of these things the video and audio appear together once it goes back through the firewire connection. Using a DSLR for live shots is still very risky, there is a lot that can go wrong. For this particular situation it worked really well, bringing out the lights of a dark Tokyo while still providing good exposure on the correspondent.

    Matthew, do you mean you can get an analog signal with no focus box or red dot out of your camera?

    Oh: no HD ?

    You’re using composite ?

    Then you could also use an old $200 ADS Pyro to do the same, or any JVC minidv recorder. That will save you a few thousands.

    great post, Matthew – please elaborate on new findings – what are the cheaper alternatives?

    What type of composite cable are you using to connect the 1d to the back of the deck? I’m trying to figure out how to use the 5Dm2 with my AJA ioHD unit and pass the signal to WireCast…
