Can anyone tell me if there is a way to use an actual switcher with vMix rather than use the computer interface?

What we would like to do is run a video switcher into the signal process to allow for live switching between multiple cameras for our live webstream of events. However, I just don't know if that is possible with a VMix setup. Anybody have any comments, advice, suggestions?

Well, I suppose that could work. However I am seeking a device that will allow to easily add multiple inputs, meaning more than two and they will be cameras to our webcasts. I just don't feel like vMix easily allows us to accomplish this compared to what something like a Tricaster can accomplish, I just don't have the budget to spend the $$ on a tricaster. So I am trying to figure out a way to accomplish it.

As mentioned, there are the shortcuts you can setup but it sounds like you want more. Like a hardware switcher with a computer interface with the feature set that vmix has. Nothing like that exists for cheap, I'd say the closest thing to that would be the Blackmagic ATEM TV studio for $1000.

vmix is just a program, if you need more inputs then you need to add the inputs to the computer, whether they be blackmagic cards, tv tuner cards, firewire cards, or whatever. I don't know everything you are dealing with, but if you are doing SD video, I personally have used a Hauppauge wintv hvr-1600 and had very minimal delay, very very minimal, so if you are wanting to do live views for whatever reason, Hauppauge cards could be a cheaper alternative to Blackmagic.

I don't think there are any plans in the near future to add full blown switcher/input hardware to the vmix product line. The only hardware that exists is the tally light setup and that is through a third-party.
