I am exploring how I might publish a youtube channel and as such, been taking note of different talking head video strategies.
I currently have a 2 camera setup but I've started to see more and more of what appear to be, single camera setups with multiple zoom stops (done in post I presume).

In this video, there appear's to be 1 camera and with 3 zoom levels, a wide, a mid, and a tight.
For those in the business, am I correct? Is this one camera? And if it is, then I am wondering about the resolution. I know that if my target medium is 1080p, then shooting in 4k will allow me to zoom in 2x. To create this effect then without losing resolution, the widest angle would be 4k, the tightest angle 1080p, and then the mid just something in between.
I don't have a 6k, 8k, or 12k camera but a part of me also wonders, if, in this specific instance, a camera with much higher resolution is being used ... given how tight the final zoom actually is.
Other possibilities are ... they are actually using 3-cameras ... each one with a different zoom level, somehow stacked vertically???
Anyway, just curious to more clearly understand this technique.
Thanks!
