Thought I'd share in case anyone is interested. I've just started to build a portable outside broadcast, multi camera studio type thing based around the Blackmagic TV studio. The intention is to use it to film stuff and either live stream it to the web, upload later to youtube or burn dvd's/blurays, but avoid editing. This setup will allow me to do all that.

I've bought some gear and tested it out (works really well and is super easy to operate) and started to put the pieces together in a case.

Very nice. Please keep us updated on the progress.

Thanks for sharing.

will do.

Got some more bits including the monitors. Went together fine but I'm having real trouble getting a signal into the television studio from the hdmi to sdi adapters.

First field test complete and successful. I'm still writing up the blog post about part 2 of the build and the adventures with getting one of the cameras to work. More soon.

What HDMI to SDI converters are you using between cameras and switcher?

Oops, never mind, I see the BM converters in one of the pix above.

Yes using the battery hdmi to sdi blackmagic ones. I had no end of trouble trying to get one of my cameras to work with it but I think it was just too old. It was an old mini dv hd camera which had a full sized hdmi port unlike the newer mini ones. It worked if i plugged it straight into the monitors but i read somewhere that's because the monitors are more forgiving. I couldn't get it to work at all with the converter.

Thought I'd put up a shot of the back and the cables and connectors as some people are asking. Simple to plug it all together.

The system ran like a dream in the first test run:

Hey Damian , yes got to love the ATEM studio.

How much of a delay is there between what the camera sees and what you see on the program monitor?

no delay at all. All the cameras are a live feed and so real time. If I record footage using the blackmagic software there's a delay of about a second from what I'm seeing on the monitor to what's on the computer screen being recorded or streamed. Is that what you mean?
