Photorealistic cinematic (offline) rendering with Unity's built-in renderer

I’m trying to render export a camera with high-quality settings that yield better quality than real-time ray tracing, but also take longer to render.

I’ve looked extensively at ray tracing setups for different cameras and how to improve the quality but I’m unable to get anything that’s, for example, comparable to the quality you get in cinematic rendering in UE4, which takes several seconds to render. Although not as good as V-RAY or Octane, this is good enough for me at this stage.

Is this possible at all with the built-in renderer and what settings should I look at?

Many thanks for your help!

ive followed this plugin, but havent had time to test yet… those images/videos look great though:
