Glitches in render

Hello, I’m having some trouble. First, the animated camera in my FBX doesn’t seem to me importing correctly. It just comes in as a static camera. Do I need to do anything to enable camera animation? Additionally, the animation speed is significantly slower than it is in the FBX, which is at 24FPS. How do I ensure the speed matches?

Second, I’m seeing some flickers and glitches in the render (see here)
There doesn’t seem to be any problems with the FBX, and I can’t find what’s causing it in the node setup (which is quite simple).
