Most all videos we see are targeting video from the weapon itself and weapons don't need the fine detail that you might expect from surveillance video.
That and you're not going to put a top of the line full color megapixel camera on the nose of a missile to get blown up.
Other videos we see are different spectrum like NV, NIR, and thermal and the US military is extremely hesitant to release anything with enough detail to determine exactly just how much capability a system might have. Remember when GPS only got you to within a few hundred feet?
Most of you don't have clearances required for surveillance videos. For well over 20+ years our military precision has been able to literally stove pipe smart bombs......scary accurate. Such graphic details today has caused other issues with troops that quickly become desensitized to everything they encounter in war today sitting in a conex and then going home to their families after their shift and acting normal. Most you will never understand this either.
