To that I’d add: make sure the background is fairly clean (it’s not swirly wallpaper with a flower arrangement sitting on a desk next to a fountain…).
Oh, and I just had an idea (that I’ve never tried). If you have access to two identical cameras, and you can mount them side by side, they will move identically. One will just be a second “behind” so to speak. You’ll have “pre-tracked” poor-man’s motion control. You’ll probably have to futz with the color some, to get it to match perfectly, but you can plan ahead for that and use a grey-card.
Also, I’d watch out for the actor’s shadow in the 2nd camera if you do this. But you could probably keep that terrible wallpaper and the flowers.
