I watched part of part 3. I see a lady using a hive tool to separate two frames by prying against the comb and tearing a large hole in the comb, in a box mixed with wood and plastic frames. Then I see a "guy??" with his hat on backward and gross looking ear implants. I didn't need to watch any more, as I didn't want those people teaching me anything.
I'm thinking you may have seen queen cells made from a drone larva in a laying worker hive. In that case, it may be horizontal. It is still a drone cell.
