The video was ill prepared and featured an obvious newcomer to animal glue... he claims hide glue "... is made from ground hides and bones and whatever of animals". It's not: Hide glue is made from animal hides and bone glue is made from animal bones. If you buy hide glue from a reputable source, it will contain pearls (not "crystals') of gelatine refined from animal hides. If you buy bone glue, it will have been rendered down from animal bones. I suspect half the unlabeled stuff you buy these days contains all sorts. To the average woodworker, there's not a great difference in performance between the two. It's more accurately termed 'animal glue'.
Animal glue is also much more dynamic than alluded to in the video: It can be as quick- or slow-setting as you desire, depending on how it's prepared. And as for all that faffing about measuring glue/water and jars with lids on... pah! Just throw some glue in the glue pot, cover with water and switch the thing on! In ten to fifteen minutes (not "a couple of hours"), you'll have useable glue.
