Nothing about this video looks faked. You can literally see the bodies being blown away by the blasts, and wounds appearing with blood splatter. On reanalysis: Blanks would do every effect seen in the video besides blood splatters, which are easily faked. Blanks will blow bodies, and hair around, and blow out windows, with their shockwave. Real shootings, especially with his caliber, are incredibly messy. Body parts come off, legs, arms, heads. With how many he was shooting, that floor would’ve been flooded with blood. People are also not absolutely silent when being shot to death. They not only scream, they gargle on the blood as they desperately gasp for life. Some people shown even have enough time to cover their faces, because those blanks would still hurt. It’s fake.
