ATEM Setup: does this work?

Hello,

I have just done my first research on multicam live streaming (so please excuse stupid and basic questions...) and came upon the Blackmagic ATEM Television Studio HD. I'm not sure if I understand all the details of the setup, so I wanted to ask if the following would work:

I was asked to do a live web stream of a rock concert that will be filmed with 3 cameras (Panasonic GH4, they have a HDMI output). As I consider buying the ATEM TVS HD I would connect the cameras via HDMI to the ATEM. 2 of the cams will be close to the ATEM (max. 2 meters), the other one is a bit further away (10-20 meters). I want to set up a PC monitor with HDMI for the multicam view and do the live editing on the ATEM. The program feed from the ATEM then goes out to my Windows laptop via USB port, where I use Wirecast or a similar software to stream the feed (and add graphics).

Here are my questions:
- Does the described setup actually work? Or do I forget any devices?
- Is the distance between Cam 3 and ATEM a problem? If yes, what can I do?
- Is doing the editing directly on the ATEM and having only the program feed on the laptop reasonable? Or is it better to do the editing on the laptop (which has only 1 HDMI input, so the next questions would be: How?)?
- Does the new ATEM TVS HD actually send out the program feed via its USB port in a way that Wirecast (or similar) can recognize? If no, do I connect the SDI output on the ATEM and the HDMI input on my laptop?

Also, if there is any simpler/cheaper way to do this I'd be happy about any hints. Thanks a lot for your help!

USB port is not a video out

The USB on this device is really only for firmware uploads... not much else.  It does NOT have an encoded video signal to it.

The ONLY Program output from the ATEM Television Studio HD (the new thing) is an HDSDI output.  There is NO HDMI program output.  To use this you would need an hdsdi capture device connected to your computer.

The 3rd camera will be a problem unless an extender is used.  ATEM things tend to be picky about hdmi lengths.  I would recommend an hdmi to hdsdi converter and then run a decent coax back to the mixer.

You need a lot of horsepower to stream multi-bitrate video.  Make sure your laptop can handle the job.  

No laptop that I know of has an hdmi INPUT.  It might have a thunderbolt input but not many windows machines would...I have never seen one... But I have not really been looking at new equipment lately.

Don't forget about audio.  Get good sound levels well before the concert.

I wish you the best on this endeavor.

we use this hdmi cable for

we use this hdmi cable for longer runs... https://www.monoprice.com/Product?p_id=14234 it is a complete fiber solution between ends and overcomes the short hdmi cable issue.

any reason to not create graphics for the ATEM to insert instead of using your streaming program for graphics?

you can use this magwell dongle to capture the ATEM pgm output on your computer. https://www.bhphotovideo.com/bnh/controller/home?A=details&O=&Q=&ap=y&c3... the captured video can then be used with OBS or Wirecast to stream to your CDN.

alternatively, you can use something like the FMuser FBE200 or Teredek VidiU (with a SDI to HDMI converter) to stream directly without a computer. I have actually started to lean this way for streaming, I like that you don't need to tie up a computer for the delivery path.

thanks for your replies,

thanks for your replies, that's very helpful! I'll get a SDI capture device to get the program feed to my laptop (looking at Blackmagic Intensity Shuttle USB right now). And I'll look into the HDMI cable thing. If I alternatively decide to run all 3 cameras into my laptop (each with a BM Intensity Shuttle USB) and do the live editing in Wirecast what specs do you think the laptop needs? I have a i7 quadcore (3.4ghz) and 8gb ram.

Don't purchase a the shuttle.

Don't purchase the shuttle. Horrible things. The usb only works on one particular usb chipset which was discontinued yrs ago.

Instead go with a magewell usb dongle or an aja u-tap. Inogeni also produce them as do epiphan.

But stay away from the shuttle.. 

Also... with a 1080 workflow you'll prob. max out the usb bus if using more than two of the above at any one time on ur laptop.
