AVerMedia have just released the ExtremeCap UVC USB 3 capture device- BU110. It has been tested with vMix and has been added to the Supported Hardware page. It works great and also looks great! They look to be retailing for $249 USD. You can find out more information about the product on their website.
I don’t usually weigh in on design but the brushed steel and LED makes for a great looking device!
USB 3 capture devices allow you to quickly add a camera source to your live video production in a matter of seconds. Typically they are plug and play so you don’t have to worry about any set up issues. There great for mobile productions where you may only need a couple of HD cameras but they’re also great for studios if you need to add an additional camera source to your existing production workflow.
