Well since my original post did a lot of research. Its common for ATEM TVS users to want to use 720p for streaming … and to be looking for cameras.
Without going into the $2000 plus range for video cameras the only options are.
A low cost camcorder + a standards converter – some exist from TVone for HD at around $300-350. Most camcorders from Sony, Panasonic don’t do 720p – just 1080p or 1080i and PAL SD.

So then it is the world of DSLR – and again you have to go over $2000 into the Nikon D800 or D4, Sony a99, and Panasonic Lumix GH2 or the new GH3. Since the GH2 is the most affordable it is really the most affordable option – perhaps a little more skill involved but with changable lenses there is a huge user base doing video work. Maybe it’s a little strange for live production. I may save up a bit more and get the GH3 if i can find stock in time for my event.

Black Magic ATEM TVS doesn’t standards convert so if you go 720p you want to

Black Magic ATEM TVS doesn’t standards convert so if you go 720p you want to have everything going native to that. I don’t see much point having standards converter and extra cabling, powersupplies – may as well have one camera.

I know it can work, but its very, very hit and miss and in my long and esteemed career of computing i got everything to work … eventually. I didn’t really get the BM shuttle to work, i even bought a pci-e USB3 card of the appropriate chipset but even though it worked for short bursts it wasn’t stable. I have 3 of the pcie intensity cards so i know all about troubleshooting BM driver and config issues.

They are saying you need to have the precise motherboard chipset and a compatible USB3. So don’t delude yourself into thinking USB3 is a mature standard when many driver upgrades seem to be released to fix many issues.
Some motherboards have a compatibility mode in the BIOS, and i get more success with USB3 external disks working reliably when compatibility mode is turned off. I never tried that with my shuttle though, i just sold it on ebay with a warning that it was very particular about its drivers. Someone bought it and then i just let go. Its so useful to have something you could use with a laptop and now i have a laptop with USB3 and the NEC chipset it tempts me to buy another and try it but common sense and painful time wasted keeps me from doing that. I sold that device to get it the hell out of my sight.

After a lot of research i think you might want to consider trying some devices from Avermedia that people seem to be using for HDMI and component capture for video game streaming, they have some USB solutions. Thats where i am heading.
