First part of movie - without lens flares
Actually, I disabled the diffraction spikes and lens flare on purpose. I found the spikes rather overwhelming when travelling the coastline. They kept obscuring my field-of-view against the background landscape features; which I wanted to be seen properly in the film. The spikes and flare look great in space, but tend to detract the player's attention away from the terrain features of the engine.
IMO the spikes should be much shorter in length and subtler at ground level, with a more subtle lens flare effect too, especially on planets with an atmosphere. The idea behind this video then; was to start with the naked eye view: with no effects, then introduce the camera's 'eye' view with its effect once it was away from the coastline.
