Similar shots with same drone in propre daylight conditions show no such "softening" as seen in these last shots. I've also checked the raw video taken in1080p D-Cinelike to verify that it wasn't a processing artefact from FCPX rendering, but the raw clips show identical blurry pictures. As the blur is stronger towards the edges, my assumption was that low light, fixed aperture resulted in some motion blur due to high speed flying with long exposure when shot in auto. I've checked the exposure values, and the shutter speed does not drop below 1/80 and ISO 1300 (could explain some of the softness?) at velocities typically at 20-25m/s. I.e., I'm not able to provide a good explanation. The softness is typically also seen in the lower resolution recording from the goggles. Any other explanation anyone?
