You don’t need to hire Thorostride to do your videos. Most of these horses are sold through agents, often large outfits, who prep them for sales and get them to the arena. that is their business. Taylor Made did their own sales videos this year and they are quite nice, probably done through their own staff. You can find the videos of their consignments on their own website.
Most of these big units have their own marketing staff. A good/decent quality camera and some basic editing software, a good turned out horse and a sunny day is all you need.
Agreed that a video can hide a lot of things but a video could certainly start conversation on a horse many people wouldn’t even lookup in the barns for further evaluation and in hindsight it can save someone time looking over every horse in the sale based on paper only to be disappointed by half of what they looked at. if they could eliminate a horse from their consideration right off the bat (based on a simple video), they can concentrate on the horses who struck their fancy. This also eliminates wasting the time and energy of sale staff presenting the horse. Sometimes spending a little extra to go the extra mile can start a trend that can pay off for both parties in the long run.
