I dunno if someone has made a refutation for that vid specifically seeing as how it's mostly just insults and such atheists are dime a dozen on youtube. But if you mean specific points then that's a different matter. Try for example the books written by Jonathan AC Brown on the topic, one titled "The Canonization of al-Bukhārī and Muslim: The Formation and Function of the Sunnī Ḥadīth Canon" and the other "Hadith: Muhammad's Legacy in the Medieval and Modern World".
