I grew up with a “Dubner” …about 7 years before I used my first Chyron, so i’ve never actually called the process a Chyron. I’ve always referred to it as a “super” “Super in….Super out” was what I called for when I used to direct the news in the early 90’s.
The pic in pic …we used to call that a DVE box, also named after the company that branded the device we used to create the effect. DVE has also become a bit of a generic term, but i’m positive the control panel we used, was actually labeled with DVE right on it.
I’ve heard dve referred to as Digital Video Effect, but it might have been a company name at one point.
The bar on the side…not sure i’ve ever seen that as a common tool. Sure, double pillarboxes were pretty common when HD first came out, and we had to place SD material into the screen, but that obviously isn’t what is happening here. I have a feeling, it is simply a design element the’ve come up with. Perhaps intended to put a list down the side of the screen.
