I couldn't find a more pronounced example of this so I hope you'll have the luck to find the scene I'm talking about.
About 1.30 minutes into the Pilot episode of Sons of Anarchy there are these guys loading crates to the truck.
I see a very pronounced motion blur on this scene.
For those who don't have the chance to see that scene, it happens a lot especially with the contrasty night scenes. Vertical contours on people from the kickers / street lamps come forward in front of the dark surroundings and when they move, you have this very blurry / videoish look.
I know this motion "artifact" is more pronounced on Panavision Genesis which I assume is used on that scene but I also keep seeing this on other cameras including Alexa. The thing is, especially for Alexa, sometimes this is more pronounced and sometimes I don't see it at all, in the scenes of identical lighting on different projects.
What creates the difference? How can we avoid it?
