I think it would be more efficient to create the new pages by hand than to automate it.
you said 100+ videos. If you have mulitple screens and you can past from one to the other creating new posts along the way and you are copying one field, someone being efficient with their time could speed through 30 to 60 new posts an hour. 2 to 4 hours would be less time then building automation that will be deleted when you’re done.
