I think you're underestimating the skill involved in making the flip book.
While you may just have one or two videos to make into flip books, I strongly suspect it will take you at least 4 or 5 attempts on the 1st one to get something that isn't a pile of crap that doesn't perform as a flip book very well, and/or falls apart almost immediately.
In the long run unless you really want to go through the process of refining the process for the enjoyment of that, it would be cheaper in both time and material costs to buy from the OP.
