It's weird, I could watch that for a while. It's sort of hypnotizing.

low speed stamping die, works well but a progressive die would feed a coil through and cut out the blank as well as bend it.

While the video demonstrates narrow parts, they are brake mounted progressive punches and dies. If this was a traditional dieset cutting and forming would speed up per part, but width of common punch press limits part length.
These resemble parts used in store-front molding; long frames and narrow punched glazing clips, punched for self tapping screws, body clearance and tap size.
Some frames are one piece, notched for clearance and tap size punched, the 'clip' becomes just a rectangular washer.
Sincerely,
