One thing we’ve been wondering: do you think there would be lots of delay in the picture? If you have 3 cameras going into the ATEM with SDI cables and then from the ATEM to a projector/screen, is there too much delay for this system to be used in a live event situation?

I think the overheating might be a problem with Canons etc. (at least the 550D gets a bit hot when shooting), but what I’ve read about GH2 is that no one has encountered any heat problems with it. No personal experience about using Panasonics though..

Thanks for the quick replies.

First of all, of course I’d be using a laptop for control and a screen/tv for the multicam monitoring. Just didn’t mention that in my post, sorry. And there’d be cables, stands, intercom etc. also included, but it’d still be a lot less to carry and a lot less expensive than traditional cameras & switcher, considering the quality you’d get.

The HDMI out of Canon’s has the problem that it shows information on the screen, but it seems you can get a clear output with the Magic Lantern. However, what I read about Panasonic GH2 is that it has the ability to output a clean image from HDMI out and show all the info on the LCD at the same time. So that’d make a very good camera for this purpose (at least until Canon makes this feature available).

One problem would also be the cable lenght of HDMI, but couldn’t that be solved by just using a HDMI-SDI converter with the DSLR’s and using SDI cables to feed the ATEM?

For the recording with ATEM, isn’t that done by just recording the H.264 feed into the laptop?
