We're already live -- but starting proper at 14:00.

See you there!

I am trying to get my head around setting up something like this:

The idea came from a potential client who wants to pull off something similiar but with a more interactive setup, where People can go to an pre-installed Ipad and "launch" the comet (for example) through the push on a button.

Here's what I've got so far:

LED screen stands on street. Pre-rendered rgba clips sit on an Ipad which is connected to an ATEM unit through Lightning->HDMI Adapter (setup as secondary Screen). A camera behind the LED screen feeds the "window content" live through HDMI to ATEM. In ATEM software the live feed is overlayed permanently with whatever comes from the Ipad. ATEM output goes to LED screen.

So when a user goes to the Ipad and chooses a clip to launch it gets played over the Ipad's output and mixed live in ATEM and then displayed on the screen in front of the user.

There are a few possible problems which I can already think of: Will the Ipad output "black" (which would then black out my live feed) when nothing is being played? Can ATEM overlay two vieo feeds, one with alpha? Will alpha even be transferred via HDMI? EDIT: No it's not. So instead of rgba I could use greenscreen footage and let ATEM do a live key?

I would very much appreciate any of your thoughts on this.

THANK YOU!

I'm a musical educator online and this will be my first time going to a live switched 3 camera setup.

Should have my first wave of gear arriving in the next few days - looking forward to getting it all setup.

I just spoke with tech support at BMD and they confirmed that the GH2s and GH3 should work together even if the GH3 is at 59.94fps (is it?) and the GH2s are 60fps - as long as one is running the latest software on the ATEM (3.4 I think).

I understand that the GH2s don't send audio via hdmi but I'm hopeful that the GH3 will as I've read a spec sheet that confirmed this (anyone know for sure?).

Cameras will be very close together. I'll be teaching guitar so I'm looking for a wide shot and a left hand closeup and right hand closeup. Hoping the Ex Tele mode works as well as reported - would save me a bundle not purchasing more lenses.

Went with the GH2/3s for their bang/buck ratio & clean hdmi. Also, I'm dslr shooter otherwise (Canon 5Diii/60d) and like the format with all it's endearing quirks ;)

Some of my work can be seen on www.tekoa.tv

Also hoping that Metabones will release their Speedbooster for M43 quickly!

A penny for your thoughts?
