The airplane in that footage is from a video game or 3d animation. It's an Su-57 or maybe an F-23 (not spending too much time on fake footage).
The missile interceptions seem real for the most part, though it can be a bit hard to tell if the scene lacks real ground clutter and context. Even going back to 15 year old mods for games like World in Conflict, very accurate missile behavior modelling and interception simulations.
