Saved scenes, Zoom ISO and a DeckLink card. How I run multi-presenter webinars at real broadcast quality, and how I got Zoom past 360p.

I didn't buy the RØDECaster Video for auto-switching. I bought it for scene management: seven custom scenes saved on the unit as A through G, previewable in real time, no macros and no third-party software.
It retired my RØDECaster Pro II completely. Bluetooth music for intros and outros, phantom power for a Shure SM7B, and audio routing so I can talk to presenters off the live mix. The Pro II is on the shelf.
Four full-screen sources, a two-up with graphics, a three-up cropped A/B/C, a four-person shot (or three plus screen share), and picture-by-picture with presenter left and screen share right for each presenter.
Only real gripe: four HDMI inputs. I want the eight-input version.
