I've been trying to figure out why my emission shader and shadows flicker in eevee when I render this as an animation. I experimented with light and shadow settings, samples, viewport and camera clip settings, z fighting issues, baking, bloom settings, nothing changes the odd effect of flickering when the animation starts. I've attached a gif of the effect with real-time material rendering to quickly demonstrate the problem, but I have also rendered many times with proper rendering.
I have also attached the .blend file.
Thanks!
