The video illustrates and almost makes it look easy the three classical modes of knapping prior to Upper Paleolithic (Spanish/English text but notice that the word silex should translate as flint and is not translated):
Mode 1: Oldowayan or Chopper industries, usually related with H. erectus
Mode 2: Acheulean, usually related with H. ergaster and derivates
Mode 3: Mousterian and MSA, Levallois technique, usually related with H. neanderthalensis and early H. sapiens
