The "Stack Folding Challenge" is to fold the two lay-outs I show in the video. But the MPMP meta-puzzle is to work out how many different Stack Folding Challenges are possible. That is to say: how many ways can you fold such a piece of paper so that the top-left rectangle is on the top, facing out.

All details about Matt Parker's Maths Puzzles are on the Think Maths website:

All the money from the sale of Stand-up Maths memorabilia goes to charity. WaterAid is working hard to provide sanitation and hand-washing facilities in places which desperately need them, so either bid on the auctions or donate to them directly. https://www.wateraid.org/uk/donate/covid-19-emergency-appeal
