    Bending across the flat is known by fabricators as 'hard way'. The process needs a bit more power due to width, but narrow cross section keeps it reasonable.
    Most important feature is the form die maintains a close fit, otherwise the bend will collapse and twist. The inside radius can (will) grow, so keep a film of high pressure lube on it, or removal likely ruins intended bend.
    Here's a HFT mod to the widely sold import bender. The material was 10ga x ~.62 HRPO. Achieving inside radius is obvious, keeping flattest possible plane the outside diameter of die barely exposed outside edge. These worked off a reference or tooling hole that controlled developing the form consistently.

    I seriously doubt the radiused parts in video 0.13 - 0.33 were cold hammer formed with out destroying at least inner side, or a whole lot of work flattening it out. It doesn't exhibit marks of any such effort.
