I finally watched this - well, skipped through, as it's somewhat slow and basic.
It's split into two halves, with the first being very much a Powerpoint presentation, with the second half being a general Q&A.
IMO too much focus was put on LOTR, Game of Thrones, and Harry Potter as examples - especially as I doubt Tolkien's style would be acceptable to traditional publishers today.
It kind of underlined that this was really pitched at beginners who don't even really know the genre.
To give an example, questions at the end included:
"What's the difference between fantasy and science fiction?"
"Fantasy always seems to be epic, but can it be a short story?".
So, if you don't really know anything about writing fantasy, it kind of serves as a simple introduction.
However, it didn't really go into any of the technicalities and IMO it would have been better pitched to a more advanced level, to better explore the writers and methods of writing fantasy - and to better prepare writers for the actual expectations of agents and editors.
