The key element here that wasn't explicitly mentioned in the video is that this would likely requre genlock to sync both cameras facing the beam splitter for this to work decently well on any moving subject. I think this is the reason they're using the Z Cam (presumably E2) cameras visible at 2:48, 3:31, 4:05, & 11:05 because that's one of the most inexpensive genlockable cameras available. This would rule out most mirrorless and prosumer video cameras unless the subject isn't moving fast or a half-frame misalignment is acceptable. Heck, a non-genlocked version of this might be preferable to weird motion blur on existing chroma keyed backgrounds. Very exciting tech
