Joshua has a Blackmagic switcher with his Lenovo laptop for his church. He's trying to put words on the live feed, with a background using the Easy Worship software. But they say he needs a video card with dual HDMI ports. Leo says that's called "Chyron," and Lower Thirds. The ATEM Switcher should be able to do it, though, even without the Easy Worship software. In fact, the ATEM doesn't need a separate computer at all - It's turnkey, try taking that out of the mix.
