Regarding interactivity and "live" communication with the audience during a show, given the usual 30-60 second delay:

@Bertl: interesting, but they don't talk about the camera to use for such setups, just a comment suggested to use something from a group called "apertus" :)

maybe informative.

Here is an article on my work: http://audio.blumlein.net/References/1308xx_ProfessionalAudio.pdf

@sebastian I got started in the Canon world, added bodies and lenses, and ML enables me to have the cameras running and recording continuously. So this is where I'm at ;-)

MagicLantern has the option to aliminate any overlays, but like I said the output is scaled down from 1920x1080 with black borders.

@ andrew: doesnt sound like a convenient live setup....

@sebastian I use EOS 550D & 600D cameras running MagicLantern. The HDMI-output is scaled down from FullHD though, so there is a frame I have to get rid off in post, and it is 59.95i with a weird cadence. I am considering getting a Teranex converter that would allow me to up-scale in realtime and change the framerate to a clean 25p.

Here is a rather incomplete list of cameras with/without HDMI overlays: http://atomos.helponclick.com/kb/article/input-sources/dslr-cameras/ninja-tests-with-popular-dslr-cameras

@andrew: how do you set up the Canon DSLRs to output a cleanfeed via HDMI or which models did you choose?

I participate in MusoTalk occasionally (http://www.musotalk.de/). They have a multiple Skype-connection-setup and live editing is done with the ATEM, the model after the TV-Studio. I myself use the TV-Studio (in conjunction with several Canon DSLR's) for live edit jobs and it works fine.

tested http://www.hitbox.tv with https://obsproject.com/ and it worked very well, they allow embedding the live stream and the stream delay was around 3-4 seconds.

Ustream isn't commercial only. Paying for a Pro account removes advertising from the stream

Didn't know it is so expensive...

It depends on the number of cameras you connect, but let's say you only have 2 or 3, you can do it with a simpler solution : some capture card (sdi or hdmi input), then use the broadcaser software to live switch between the cameras.

https://www.blackmagicdesign.com/products/atemtelevisionstudio 1000$ live switcher for up to 6 SDI/HDMI live sources.
Requires external monitor and computer with control software. Probably the cheapest available solution currently available.
Also does h264 encoding to connected computer for live broadcast.

True, we could afford it now, but I want to first see what is available and what has the best value in case we decide to get a paid service.

does it need to be free? can't we put some money for this? It's usually not that expensive
