What size and model is that Large Softbox on Day one. I think he is shooting with Claudine. it is much bigger than the 12x50 shown in his "gear used" list.
was that the section to compare the soft box with a shower curtain? If I remember correctly, that was a 3'x4' box. I don't know the brand. It was a rental from Glazer's camera, and they have a mix of Photoflex, Westcott, and Chimera in their rental department. Looking at the video, it appears to be a Chimera with a flat front (no lip extending around the edges).
The 12x50 is the strip box that we used on other sections.
