You can't draw great conclusions from the Ukraine videos

Ukraine videos serve perfectly well to corroborate the intelligence we have from other sources. Maps of the invasion show stalled Russian forces. Radio intercepts reveal disfunction. Casualty estimates from multiple sources, including Russia itself, demonstrate fierce resistance.

So when dozens of Ukraine war videos emerge and we see one APC full of Russian conscripts after another cooking off after a missile strike it serves us pretty well in understanding the dynamic.
